What is a GFCI outlet?

The term GFCI means Ground Fault Circuit Interrupter.

This outlet is slightly different from the regular outlets.

GFCI trips if it senses problems like overloading, faulty wirings, or short circuits.

It comes with the test and reset buttons used to test the outlet and reset it when tripped. 

These buttons are absent in the regular outlets.

Besides, GFCIs are slightly bigger than regular outlets. 

Other than these, there are no other differences. 

GFCI outlets are mostly used in kitchens, bathrooms, laundry rooms, and garages.

These are the areas with the risk of moisture and overloading. 

Let’s examine some reasons behind GFCI outlet tripping without load.

Why is my GFCI tripping without load?

There are various reasons behind GFCI tripping without any load. 

If you find the problem without plugging in, then the following conditions could be responsible for your GFCI outlet tripping:

1. Current leakage

The outlet may trip without load due to the current leakage from the wires. 

The currents may leak due to the damaged, old, and worn-out input wires. 

The wire’s insulation also might be damaged or worn out, causing the current to leak and make the outlet trip without any load.

2. Damaged wires

The damage in the wires can be anywhere besides the input wire. 

Pests or insects might have entered and chewed the wires inside, for which the wires have got badly damaged. 

Even with no or low loads, the outlet will keep tripping.

3. A loose wire in the outlet

Wiring issues are a real problem in electrical matters. 

If your GFCI outlets trip without load, the wirings might be a problem. 

The wires have become loose anyhow. 

If you do not fix the wires, the outlet will trip without appliances plugged in.

4. Moisture in the outlet

Another major cause behind GFCI tripping without load is moisture. 

Somehow, moisture makes its way into the outlet and begins to accumulate inside the outlet. 

Outdoor installations and rains are the most common culprits in moisture getting into the outlets. 

Another reason is high humidity.

Areas like Florida have very high humidity, resulting in moisture build-up inside the outlet and making it harder to evaporate. 

If you suspect such a thing, turn off the circuit breaker and open the outlet box to confirm the problem.

While resetting the outlet, make sure the outlet is dry.

Otherwise, it will trip again, with or without load. 

If the outlets are outdoors or near wet and humid areas like kitchens and bathrooms, ensure the box is weatherproof and locked well.

Exposure to moisture can also lead to short circuits.

You can also use a moistureproof GFCI like this one.

5. Faulty GFCI outlet

If there is no problem but still the outlet trips despite having no loads, the problem could be in the outlet.

Maybe the outlet is defective.

The GFCI outlets have a highly responsive internal circuit system that detects maximum electrical flaws and keeps tripping even if there is no load. 

You will have to repair or replace the outlet. Call a professional instead to get the job done.

6. Electricity fault

GFCI outlet constantly tripping without any load might be due to electrical faults, like faulty structural wirings, outlet connected to the faulty circuit breaker, etc. 

Here also, you will require a professional.

7. Ground fault

A ground fault occurs when a hot wire comes in contact with the ground wire. 

The ground wire is not supposed to have any current.

But, if you connect it to the hot wire, it becomes life, and the current starts flowing. 

As a result, the wire fails to save you from short circuits.

It starts carrying more current than the circuit.

Ground faults can electrocute people or buildings without GFCI.

But, if you have GFCIs, it will trip off without delay, despite having no load.

You should consult an electrician if the outlet trips due to a ground fault.

8. Defective appliance

Even if there is no load in the GFCI outlet, an outlet downstream connected to a defective appliance can trip the GFCI. 

Connecting a defective appliance to the GFCI outlet will make noises like humming or buzzing.

Repeated appliance use will slowly deprive the outlet in the chain of power. 

Ultimately, the GFCI outlet will trip. 

If one outlet gets affected, all the outlets (even those without load) will get affected. 

So, it is necessary to examine all the outlets downstream to see if any such appliances are connected to them or not.

Even if you have only one such appliance connected to the outlet, it will cause constant tripping of other outlets downstream without load.

What should I do if GFCI keeps tripping without load?

When a GFCI outlet keeps tripping, your first job is to find a way to fix it. 

But, the methods of fixation depend on the causes of tripping.

Reset the outlet

GFCI outlets come with a set of test and reset buttons. 

The first and easy method of fixing the tripped GFCI is to press the ‘RESET’ button. 

Pressing the button will restore the power to the outlet and make it active. 

However, if there have been some other issues, consult an electrician to find the issue and fix it.

Unplugging appliances

If the tripping happens due to the constant plugging in of the defective appliances, unplug the device. 

But first, you have to identify the defective appliance.

Find out which plugged-in appliance makes noises.

Once you unplug the device and see that the outlet has stopped tripping with or without load, you can declare that the appliance was the problem. 

But, if the GFCI still doesn’t stop tripping, it may be due to another cause.

Replace the outlet

GFCI will keep tripping with or without load if the outlet is at fault. 

In such a case, you have to replace the whole outlet.

It can be due to defective, damaged, or old and worn-out outlets. 

You can also install a GFCI at each outlet.

It will prevent the tripping of unloaded outlets due to the defective appliance.

Hire an electrician

You should call an electrician if you cannot understand why the GFCI outlets keep tripping without having any load or appliances plugged into them. 

Electricians have good knowledge about these things.

They can help you identify the problem behind the tripping and fix the outlet. 

In most cases, the wiring defects will require an electrician, like the loose connections, damaged input wires or insulation, etc. 

The electrician than the laypersons better does these. 

Besides, some areas do not allow laypersons to deal with electricity.

So, you cannot fix the outlet if you do not call a professional.

Why will GFCI trip if I plug in an appliance?

Have you ever wondered why GFCI trips whenever you try to load something? 

It is not yet loaded properly, but it trips whenever you plug in any appliance. 

Here are some common reasons:

Loose wire connections

A loose wire connection can make the GFCI trip. 

Though there has been no constant load, the moment you plug in an appliance, it will trip. 

Call a professional to confirm any loose wire connections or leakage that makes the outlet trip immediately after loading.

Moisture accumulation inside the outlet will make it trip whenever you load any appliance. 

It occurs mostly in outdoor outlets, kitchens, and bathrooms. 

Open the outlet to check the moisture problem and make sure it is dry while putting it back. 

Otherwise, the outlet will keep tripping unless it has become dry, with or without load. 

You can use a blow dryer, but consult an expert before doing such a thing.

You might be using an appliance that uses loads of electricity, and your outlet cannot handle such a load. 

Such appliances can overload the outlet and make it trip constantly. This tripping is good as it saves you from short circuits. 

Do not use such appliances. 

Sometimes, overloading can occur due to loose or damaged wirings.

In this case, the GFCI will trip even if there has been no load for some time.

GFCI defect

If none of the above is the problem in your outlet, the last option is a defective outlet. 

It doesn’t matter if you load anything or you don’t.

A defective outlet will always trip whenever you try to plug in something or if there is no load.

What other problems a GFCI outlet may face?

Besides so many problems, a GFCI outlet can face many other problems, with or without any load. Below are some common GFCI problems:

GFCI tripping immediately

If your GFCI outlet is tripping immediately after plugging appliances, the reason is probably a defective outlet. 

It would be best to replace the outlet.

If the outlet is fine, but it still trips immediately, the problem is in the wiring.

Hire a professional to deal with it.

GFCI breaker tripping

If the breaker is tripping, it could be an old and worn-out breaker, loose or damaged wiring, overloading, or a malfunction in the appliances you have plugged in. 

If you cannot understand the problem, call an expert.

GFCI outlets tripping after rain

If the outlet is outside, there are higher chances of the outlet tripping after recent rains. 

Rains can accumulate moisture inside the outlet for which it is constantly tripping with or without loads. 

If your GFCI is inside, check for leakages from where the water can enter your home and outlet. 

Check the appliance you have plugged in if your outlet is protected with covers.

Water can enter the outlet through the appliance if it has a damaged jacket.

GFCI tripping in the rain

If the GFCI trips, rainwater enters the outlet or the power cord. 

It occurs when the outlet is outside, and the owner forgot to protect it by covering it. 

Also, check the power cord jacketing.

GFCI tripping every few days

GFCI outlets interpreting a surge as the ground fault can lead to GFCI tripping every few days. 

Surges do not always occur due to poor wiring systems or power supply malfunction. 

Surges also occur by starting heavy-duty appliances, like freezers. 

Freezers use a lot of power when they start.

Once the power falls, the extra current drawn is redistributed through the circuit, thus causing a surge. 

So, if you have heavy-duty appliances you use once every few days, your outlets tripping after every few days is common. 

You should also check for moisture, debris, and insects for GFCI outlets tripping.

In which places the GFCI outlets can trip?

Let’s take a look at the places where this can happen.

Bathroom outlets are prone to moisture accumulation. Somehow, the moisture enters the outlet and gets accumulates inside it. 

It causes a ground fault and constant outlet tripping despite having no loads. 

If your outlet is protected, the outlet outside the bathroom makes the other outlets trip. 

Maybe you have plugged in a heavy-duty or faulty appliance, for which all the other outlets get deprived of power.

Here also, you need to look for the moisture sources. 

Heavy storms and rain can add water to the outlets, especially if they are not covered well. 

Insects and debris could also be responsible.

Kitchen 

The kitchen is also a moisture-prone area.

So, outlets accumulating moisture and tripping are common. 

If moisture is not the problem, see if you use any heavy-duty appliances, like microwaves. 

Fridges can overload the outlet and trip it.

Devices like water heaters and sump pumps staying in the basement can make your GFCI trip frequently because they consume excessive current.

Besides, basements are somewhat damp areas.

So, moisture accumulation in the outlets and outlet tripping are common.

Poor grounding and reverse polarity in the campers can cause GFCI tripping. 

Defecting outlets, wrong wiring, malfunctioning, etc., can cause leakage.

GFCI outlet tripping near the hot tubs includes bad heating, loose connections, burnt wires, or corrosion.

The tub water also enters the outlet and makes it trip constantly.

Loose connections, worn-out insulation, moisture, and leaks in the generator can make the outlet trip with or without load.

Heated floor thermostat

Wrong wiring in the thermostat can make the GFCI outlet trip constantly with or without any load. 

Conflict in the power supply will also do the same thing.

Final thoughts

There could be multiple reasons behind GFCI tripping without load, like leakage, damaged and worn-out wires, loose wires, moisture accumulation inside the outlet, and ground fault. 

Even if the outlet is on load, more or less the same reasons are responsible for tripping. 

The GFCI trips differently, like tripping immediately, every few weeks, after rains, during rains, or breaker tripping. 

Solve the issues whenever you find the real problem. If you cannot find the real cause behind the GFCI tripping without load, call an electrician, especially if the wires or outlets need changes.

Why a GFCI Keeps Tripping (Solved)

Hubert Miles | Licensed Home Inspector, CMI, CPI

Updated on February 17, 2024

There are several different reasons why a GFCI keeps tripping. The most common reason is water or moisture that has gotten into the receptacle box or outlet. However, a tripping GFCI device could also get caused by an overloaded circuit, a malfunctioning outlet, electrical issues, or improper installation. 

According to the National Electric Code (NEC), you must install Ground Fault Circuit Interrupter (GFCI) outlets and breakers in specific locations throughout your home. GFCI protection offers an extra layer of protection to your home’s electrical system. Still, they can be highly inconvenient if they’re constantly tripping and killing power to your outlets. 

When a GFCI keeps tripping, it’s inconvenient, but it often happens for a reason. You must get to the root of the cause behind your tripping outlet or breaker, especially if the electrical problems persist. It’s also essential to understand the purpose of GFCI devices and why electricians install them in the first place.

What is the Purpose of GFCI? 

Ground fault circuit interrupters protect you from a fatal electrical shock around your home. GFCI devices can detect small electrical leaks between hot wires and neutral wires.

A ground fault occurs when the incoming electrical current flow exits on the hot side of the outlet but doesn’t return the same electric current flow to the neutral side. If the current flows aren’t the same, the device will trip and terminate electricity like a breaker. 

An electrical leakage current is when the electric current deviates from its intended path. The electric leak will attempt to take the shortest unintended path to the ground, creating an electric shock that can be fatal.

While there’s usually a good reason for a GFCI outlet to trip, it can also happen accidentally. Accidental trips are highly inconvenient and are often the result of improper wiring or installation or a faulty outlet. However, whenever a GFCI outlet is not working , you must get to the bottom of the problem, or it will keep happening. 

What Causes GFCI to Trip? 

Troubleshooting your GFCI devices is often a process of elimination. There are five main reasons why these outlets and breakers trip, and it’s challenging to put your finger on the right one without an in-depth investigation. To help you get started, let’s go over the five main reasons why GFI outlets trip and what to do about it. 

There is Moisture Near the Outlet 

The most common reason GFCI outlets trip is because of moisture or water in the outlet or outlet box. Water is hazardous around electricity, so GFCI outlets often get installed in potentially moist areas. These include bathrooms, kitchens, laundry rooms, outdoor areas, and unfinished basements or attics. 

A physical splash of water is typically the cause of moisture in an outlet box and is easily detectable. However, in humid areas, such as Florida, it’s also possible for enough humidity to accumulate inside the outlet and cause it to trip.  

The best way to prevent this is to install a new GFCI outlet and box with extra protection. Modern GFCI outlet boxes are waterproof and can withstand rain, humidity, and flooding. You should replace your old GFCI outlet with one to prevent further tripping. 

Exterior outlets need GFCI protection and a bubble-type weatherproof cover to keep moisture at bay.

An Overloaded Circuit 

Another common reason your GFCI will trip is an overloaded electrical circuit. An overloaded circuit happens when you are trying to operate too many appliances or electrical devices on the same circuit. Depending on the size of your electrical wiring, your GFCI circuit can only handle so much power. 

An overloaded circuit can short circuit due to faulty or exposed electrical wiring. If two exposed wires are touching one another, it will cause the GFCI breaker or receptacle that’s powering them to trip. Unplug all the devices receiving power from the GFCI circuit breaker or outlet to determine if an overloaded circuit is a problem. 

Next, plug everything back in, one device at a time, and see if the problem reoccurs. If it does, an overloaded circuit is likely the cause of your tripping GFCI.

Plugging appliances in one at a time is also an excellent way to determine which appliance is causing the problem. It may be necessary to wire it into a separate circuit or run a new circuit entirely. 

A Ground-Fault Occurrence 

Ground faults are when the hot wire touches the ground wire or something grounded. Ground faults get caused by several different things, including: 

• Worn out insulation 

The older your electrical wiring is, the more likely it is to have worn-out wiring insulation. When the insulation wears down enough, the hot wire can contact the ground wire and cause a ground fault. 

• Corroded wires 

The same is true for corroded or pinched wires.  

• Dust or debris 

If enough conductive dust collects in the outlet box, it can become an electrical conductor and leak electricity from the hot wire to the ground. 

• Loose connections

When either a hot or neutral wire connections are loose, arcing (short circuit) occurs, which will trip the GFCI. The loose wire connection can be anywhere on the branch circuit between the circuit breaker and the GFCI receptacle outlet.

If you can’t visibly see the ground wire touching the hot wire, there’s still possibly enough electricity leakage to cause a tripped GFCI. You should contact a professional electrician or use an electricity leakage tester to see if this is the problem. If the insulation is worn enough, electricity can leak from the hot wire onto the ground. 

• Defective appliances

A defective appliance can cause GFCI tripping to occur. A hairdryer can be a defective appliance. Defective electric motors inside common household appliances can cause current leakage, tripping a GFCI.

Nuisance Trips from a Refrigerator or Freezer

When a refrigerator trips a GFCI outlet, this usually means that it is drawing too much power from the circuit, usually when the compressor turns on. To prevent further trips, check if too many appliances are plugged into the same circuit and unplug any unnecessary items.

In older homes, it’s common for the kitchen lights and outlets to share one circuit. Since the refrigerator shares the circuit, the excessive draw can cause the refrigerator trips the GFCI breaker or outlet.

Be sure the outlet your refrigerator is plugged into has a 20-amp rating. If not, consider installing a dedicated 20-amp circuit for the refrigerator.

Many people like to put a spare refrigerator or freezer in their garage . These can often trip GFCIs that the NEC requires inside garages. If your new refrigerator keeps causing GFCI outlet trips, consider plugging it into a different outlet or installing a dedicated circuit.

Your Outlet Has Gone Bad

Like all electrical devices and components, outlets tend to go bad. On average, GFCI outlets last 15 to 20 years, but they can last longer or shorter depending on how your licensed electrician installed them. However, a faulty GFCI outlet will trip for no reason other than that it can’t handle electricity. 

It’s good to test your electrical outlets once a month by pushing the TEST button on the outlet’s face. If it trips, the power outlet is working as it should. Press the RESET button once you have finished your test. 

Improper Installation 

Finally, it’s possible that you or an electrician didn’t install the GFCI outlet correctly. GFCI outlets have to get wired a certain way, and attaching the wrong wire to the wrong spot will cause your device to trip endlessly or not work. 

How to fix a GFCI that Keeps Tripping? 

When a GFCI outlet keeps tripping, it signals that a problem exists and needs your attention. The only way to permanently fix a GFCI that keeps tripping is to get to the root of the problem.

Nuisance tripping occurs when a GFCI trips for no apparent reason. Getting to the source of the problem of nuisance trips is the only way to ensure that tripping doesn’t reoccur, and you should take this seriously.

Your qualified electrician will likely need to replace the GFCI outlet or breaker and ensure no loose connections exist.

GFCI Keeps Tripping FAQs 

When a GFCI keeps tripping, you probably have questions about how to troubleshoot why nuisance GFCI tripping occurs frequently.

Can moisture cause a GFCI to trip? 

Moisture is one of the leading causes of a tripping GFCI outlet. Water can result from excess humidity, rain, or flooding. 

Will a GFCI trip if it’s overloaded? 

A circuit overload is when you try to power too many devices on the same circuit, and it will cause your GFCI to trip as a safety measure. 

What causes a GFCI to trip repeatedly?

A GFCI may repeatedly trip if there is an electrical fault, such as a short circuit, or a ground fault, meaning the electricity exits the outlet via an unnatural path. It can also be caused by moisture exposure, worn-out wiring, overloaded circuits, or a bad GFCI sensor.

Final Thoughts 

While tripping GFCI outlets is inconvenient, it’s a safety measure. In most cases, a tripping GFCI outlet is good and prevents you from getting electrocuted. These devices rarely trip for no reason, but they can happen. Whether you perform tests yourself or hire an electrician, you must get to why your GFCI is tripping in the first place.

Troubleshooting Guide: What to Do When Your GFCI Keeps Tripping

Ground Fault Circuit Interrupters (GFCIs) are crucial electrical safety devices that protect us from electrical shocks and potential hazards. However, it can be frustrating when a GFCI repeatedly trips, disrupting power to multiple outlets. Let’s explore the common causes behind GFCI tripping and provide a step-by-step troubleshooting guide to help you resolve the issue.

Role of a GFCI

To effectively troubleshoot a GFCI tripping issue, it’s essential to understand how it works. A GFCI monitors the electrical current flowing through a circuit. If it detects even a slight imbalance, such as current leakage due to a ground fault, it automatically shuts off the power to prevent electric shock.

Identify Potential Causes

There are several potential causes for GFCI tripping that you should be aware of. Here are a few of the most common causes you may encounter:

Ground Faults

The most common cause of GFCI tripping is a ground fault. This occurs when a hot wire encounters a ground wire or conductive material, creating a short circuit and causing the GFCI to trip.

Overloaded Circuits

GFCIs are designed to handle a specific amount of current. Overloading the circuit by plugging in multiple high-power devices simultaneously can cause the GFCI to trip.

Faulty Appliances or Wiring

If a specific appliance or wiring in the circuit has a fault, it can trigger the GFCI to trip. Identifying the faulty device is crucial to resolving the issue.

Resetting the GFCI

When the GFCI trips, the first step is to reset it. Locate the GFCI outlet or breaker and press the reset button. If it clicks and stays in place, the issue may have been a temporary fault. However, if it immediately trips again, proceed with the following steps:

1) Isolate the Problem

Unplug all devices from the GFCI-protected outlets.

2) Reset the GFCI

Gradually plug in one device at a time and reset the GFCI after each plug-in. If the GFCI trips after plugging in a specific device, that device may be faulty and needs further inspection or repair.

3) Check for Ground Faults

Inspect outlets, switches, and connections for damage, security, exposed wires in the circuit, and moisture in areas like bathrooms or outdoor outlets to prevent ground faults.

4) Address Overloaded Circuits

Identify outlets connected to the GFCI circuit and consider redistributing the load by connecting certain devices to non-GFCI outlets.

5) Seek Professional Help

If the issue persists or you are uncomfortable dealing with electrical troubleshooting, it’s best to contact a qualified electrician. They have the expertise to identify and resolve complex electrical problems safely.

Common Causes of GFCI Outlets Keeps Tripping and How to Troubleshoot Them

Why Do My GFCI Outlets Keep Tripping?

Common causes of gfci outlets tripping, outlet keeps tripping after reset, outlet keeps tripping with nothing plugged in, outlet keeps tripping when i plug something in, outlet keeps tripping without load, how to troubleshoot gfci outlet tripping.

• Check for Ground Faults: Inspect the vicinity of the outlet for indications of moisture, like water leaks or dampness. Ground faults, which can cause GFCI tripping, can occur due to moisture. It's crucial to promptly address any water-related problems to prevent potential ground faults and ensure the safety of the electrical system.
• Inspect Wiring Connections: To prevent GFCI tripping, it is important to inspect the wiring connections within the outlet box. Check for any loose or damaged wires, as they can cause a GFCI to trip. Safely turn off the power to the outlet and carefully examine the connections, tightening any loose screws or terminals for proper installation and secure connections.
• Test GFCI Outlet Functionality: To ensure the functionality of a GFCI outlet, press the "Test" button to simulate a ground fault and check if it trips correctly. Afterward, press the "Reset" button to restore power. If the GFCI fails to trip during testing or doesn't reset properly, it indicates a potential fault, and the outlet should be replaced to maintain electrical safety.

Why Does My GFCI Keep Tripping with No Load? Understanding the Reasons

Jan 30, 2023

Filed under : GFCIs

Have you ever had an electrical outlet that just wouldn't cooperate? You plug something in, and the GFCI (Ground Fault Circuit Interrupter) trips, even when there's no load on it. It can be frustrating and confusing, but there are reasons why it happens. In this article, we'll take a closer look at why your GFCI might keep tripping with no load, and what you can do about it.

Table of Contents

Introduction, what is a gfci, faulty gfci outlet, overloading the circuit, ground fault in another outlet, water damage, faulty appliance, how to troubleshoot a gfci that keeps tripping with no load.

A GFCI outlet is designed to protect you from electrical shock by shutting off power to the outlet when it detects a ground fault. This is a critical safety feature that can save your life. However, sometimes a GFCI outlet can trip for no apparent reason. When this happens, it can be frustrating and inconvenient. In this article, we'll explore some of the reasons why a GFCI outlet might keep tripping with no load, and what you can do about it.

Before we dive into the reasons why your GFCI might be tripping with no load, let's quickly review what a GFCI is. A GFCI outlet is designed to protect you from electrical shock by shutting off power to the outlet when it detects a ground fault. A ground fault occurs when there is a path for electrical current to flow from a grounded source (such as a metal appliance) to a person. This can happen if there is a fault in the wiring or if an appliance is damaged.

Reasons Why a GFCI Keeps Tripping with No Load

There are several reasons why a GFCI might keep tripping with no load. Here are the most common ones:

Sometimes, the GFCI outlet itself is faulty. If this is the case, the outlet will need to be replaced. This is especially true if the GFCI outlet is old or has been exposed to water.

Another common reason why a GFCI might trip with no load is that the circuit is overloaded. If you have too many appliances plugged into the same circuit, it can overload the circuit and cause the GFCI to trip. To prevent this from happening, try unplugging some of your appliances and see if that fixes the problem.

Sometimes, a ground fault in another outlet can cause the GFCI to trip, even if there's no load on the GFCI outlet. This can happen if the other outlet is connected to the same circuit as the GFCI outlet. To troubleshoot this issue, you'll need to go around your home and check all the other outlets connected to the same circuit. Look for any signs of damage or water exposure, and make sure all the outlets are working properly.

Water damage can cause a GFCI outlet to trip, even if there's no load on the outlet. If the outlet has been exposed to water, it may need to be replaced. Water can damage the wiring and cause a short circuit, which can trip the GFCI.

Finally, a faulty appliance can also cause a GFCI to trip, even if it's not plugged into the GFCI outlet. If you have an appliance that's damaged or has a short circuit, it can cause the GFCI to trip. To troubleshoot this issue, unplug all your appliances and then plug them back in one at a time until you find the one that's causing the problem.

If your GFCI outlet keeps tripping with no load, here are some steps you can take to troubleshoot the issue:

• Unplug all your appliances and try resetting the GFCI outlet. If it doesn't trip, then one of your appliances is causing the problem.
• If the GFCI outlet still trips with no appliances plugged in, try resetting it again and then plugging in one appliance at a time until you find the one that's causing the problem.
• Check all the other outlets connected to the same circuit and look for signs of damage or water exposure.
• If none of these steps solve the problem, you may need to replace the GFCI outlet.

Remember, electrical work can be dangerous, so if you're not comfortable troubleshooting the issue yourself, it's always best to call a licensed electrician.

If your GFCI outlet keeps tripping with no load, there are several reasons why this might be happening. It could be a faulty outlet, an overloaded circuit, a ground fault in another outlet, water damage, or a faulty appliance. By following the troubleshooting steps we've outlined in this article, you should be able to identify the problem and fix it.

Q: What is a GFCI outlet?

A: A GFCI outlet is designed to protect you from electrical shock by shutting off power to the outlet when it detects a ground fault.

Q: Can a GFCI outlet go bad?

A: Yes, a GFCI outlet can go bad over time, especially if it's old or has been exposed to water.

Q: Why does my GFCI outlet keep tripping?

A: There are several reasons why a GFCI outlet might keep tripping, including a faulty outlet, an overloaded circuit, a ground fault in another outlet, water damage, or a faulty appliance.

Q: How do I troubleshoot a GFCI outlet that keeps tripping?

A: To troubleshoot a GFCI outlet that keeps tripping, unplug all your appliances and try resetting the outlet. If it still trips, try plugging in one appliance at a time until you find the one that's causing the problem. Check all the other outlets connected to the same circuit and look for signs of damage or water exposure. If none of these steps solve the problem, you may need to replace the GFCI outlet.

Q: Can I replace a GFCI outlet myself?

A: Electrical work can be dangerous, so if you're not comfortable working with electricity, it's always best to call a licensed electrician. However, if you have some experience with electrical work and feel confident in your abilities, you can replace a GFCI outlet yourself.

Why GFCI Keeps Tripping With Nothing Plugged In?

GFCIs will trip when they encounter a ground fault. But that is supposed to happen when you plug an appliance into the GFCI outlet. What happens when your GFCI starts tripping even though it doesn’t have anything plugged into it. Sometimes, the GFCIs are simply bad. But as the guide below will soon show you, that doesn’t apply to every single situation.

What Causes A Breaker To Trip When Nothing Is Plugged In?

You have to consider the possibility that the GFCI is defective or damaged. This happens all the time. Though, if you don’t believe that the GFCI has gone bad,  It is also due to the damaged input wire. A damaged input wire can cause a leakage in the current.

A damaged input wire is not simply a nuisance. It is dangerous. Your GFCI keeps tripping because it wants to protect you. Stop resetting it until a professional resolves the problem.

Before you call a professional, you should check to ensure that nothing is plugged into the GFCI. Some homeowners attach GFCIs to every single outlet. Others use a single GFCI to protect multiple outlets downstream.

Even though the outlet with the GFCI doesn’t have anything plugged into it, if an outlet downstream is connected to an appliance, a defect in that appliance could cause the GFCI to trip , depriving all the outlets in the chain of power.

This is the reason why this configuration is so problematic. A fault in one outlet will affect all the outlets . The only way to conclude that you don’t have any devices plugged into the GFCI is to check all the outlets downstream .

If you have at least one appliance plugged into one of the outlets downstream, that appliance could be the cause of the incessant tripping.

What To Do If GFCI Keeps Tripping?

The solution you will apply will depend on the cause of the tripping, for instance:

1). Unplug Appliances

If you have an appliance plugged into one of the outlets downstream, unplug it. If the tripping stops, you can comfortably conclude that the appliance was the problem. If plugging other appliances into the outlet causes the GFCI to trip, the GFCI is the problem. If the appliance is at fault, unplugging it should resolve the situation.

2). Hire An Electrician

You have to hire an electrician. They will identify and then fix the source of the leakage.

3). Replace Defective GFCI

If the GFCI has gone bad, your only solution is to replace it. If you have the means, you should also consider installing a GFCI at each outlet. That way, a fault in an appliance plugged into one outlet won’t affect the other GFCI outlets.

How To Fix Tripped GFCI Outlet?

If the GFCI has tripped, the only thing you can do is to press the ‘RESET’ button. This will restore power to the GFCI outlet.

Why GFCI Outlet Keeps Tripping When I Plug Something In?

If your GFCI Outlets keeps tripping regardless of what you plug into it, one or more of the following might be the cause:

1). Loose Wiring

A loose connection in the GFCI outlet can cause nuisance tripping. Tripping is a good thing here because it is protecting you and your equipment . You should hire a professional to check the GFCI for other sources of current leakage. They may identify old and worn-out insulation in the GFCI.

2). Moisture

According to  David Gray Online , if you have moisture in the GFCI outlet, it can cause incessant tripping. This can happen to outdoor outlets that have been exposed to rain.

It can also happen to indoor outlets in regions with a lot of humidity. Moisture will accumulate in the receptacle box. The GFCI will keep tripping until the water is removed.

3). Overload

If the appliances you keep plugging into the GFCI are too powerful, they can overload the GFCI by causing more current to flow through the outlet than it was designed to handle. On occasion, an overload occurs, not because the appliances are too powerful, but because of a loose or corroded connection. The GFCI will respond to the excess current by tripping.

4). GFCI Defect

If you rule out every other possible cause, you should consider the possibility that the GFCI has gone bad.

Some Other Problems Related To GFCI:

Gfci breaker tripping immediately.

If your GFCI trips immediately, regardless of whether or not it has something plugged into it, the GFCI is most likely defective. You should replace it. If the GFCI is fine, then it was probably not wired correctly. You need an expert that can open it to identify the source of the problem.

GFCI Keeps Tripping Breaker

The breaker in the GFCI can trip for several reasons, including a worn-out breaker, improper wiring, overloading, and a malfunction in the connected appliances, to mention but a few.

GFCI Outlet Keeps Tripping After Rain

If the GFCI is outside, the rain is introducing water to the outlet, causing a ground fault. If the GFCI is inside, you should look for a leak that allows water to enter your home whenever it rains.

If the GFCI outlet is covered to protect it from water, investigate the appliance. If the appliance has damaged jacketing, rain could introduce enough moisture to cause a short which, in turn, trips the GFCI.

GFCI Keeps Tripping In Rain

If the GFCI keeps tripping, rainwater is either infiltrating the outlet or the power cord. This can happen in situations where a homeowner has failed to add covers to exterior outlets. This can also happen if the power cord has damaged jacketing.

GFCI Trips Every Few Days

A GFCI can interpret a surge as a ground fault. This can cause it to trip. Surges are not always caused by poor wiring or a malfunction in the main power supply. You can cause surges in your home by activating a heavy-duty appliance.

Items like freezers use a lot of power when they first start. Once their power demands fall, the excess current they had drawn is redistributed throughout the circuit. This can result in a surge.

If you have heavy-duty appliances that you use once every few days, they may be responsible for the trips you encounter every few days. If surges are not the problem, check the GFCI receptacle box for moisture, debris, and insects.

GFCI Keeps Tripping For No Reason

You can blame random, unexplained tripping on moisture in the receptacle box, worn-out insulation, overloading in the circuit, and a defective GFCI. Conductive dust and debris in the outlet can also produce a ground fault.

GFCI Trips Right Away

The GFCI is either defective or has a loose connection. You should keep an eye out for worn-out or damaged insulation, not to mention water and debris in the receptacle.

GFCI Trips Randomly

The issue of a current leakage caused by old or damaged insulation causes GFCI to trip randomly.

The Places Where GFCI Can Trip

• Bathroom outlets have moisture in their vicinity. More than likely, water has infiltrated the bathroom outlet, causing a ground fault.
• If the bathroom outlet is just one among many protected by a GFCI upstream, you should consider the possibility that another appliance plugged into one of the outlets outside the bathroom is causing the GFCI to trip, depriving all the outlets of power, including the ones in the bathroom.
• Look for sources of moisture. A heavy storm can introduce water to the interior of a garage. If that water infiltrates the GFCI outlet, it will trip whenever you use it.
• Insects and other types of debris in the receptacle box can produce a similar result.
• You should also check the appliances plugged into the outlet. Large items with motors such as refrigerators have a tendency to cause nuisance tripping in GFCI outlets.
• The kitchen can expose an outlet to water and debris, resulting in a ground fault.
• If the water is not the problem, check the appliances. Fridges have a reputation for causing GFCIs to trip.
• If the fridge isn’t the problem, heavy-duty appliances like microwaves can trip a GFCI by drawing more power than it can handle. They will do this not only because they are powerful items but also because of a malfunction.

If you keep heavy-duty items such as water heaters and sump pumps in the basement, their combined load can cause either the GFCI or the circuit breaker to trip. It is also worth noting that basements are typically damp places that encourage moisture to either infiltrate or accumulate in the receptacle box, eventually resulting in a ground fault.

It is due to poor grounding or reversed polarity. A defect, malfunction, or improper wiring is causing leakage to the ground.

Common causes of tripping in this situation include a bad heating element (as well as a heating element short), loose connectors, burnt wires, and corrosion (of the electrical contacts). Naturally, if water from the tub enters the GFCI, it will trip.

The GFCI will trip because loose connections, worn insulation, moisture, contact with human skin, or some other defect has caused an electrical leak.

The appliances plugged into the GFCI, such as fridges and converters, can cause it to trip. Other potential causes include faulty wiring, loose connections, and a faulty GFCI.

The improper wiring can cause tripping in the GFCI. The issue on a short to ground as well as a conflict in the power supply circuit.

GFCI breaker tripping with no load

• Add to quote

This one I can't figure out. I have a GFCI breaker that according to the label it feeds the back door outside plug and it use to feed an outlet for a soaker tub in one of the bathroom. I did some Reno's last year and took out the plug near the soaker tub and moved it to the hallway. Had no issues at all until roughly few weeks ago. The GFCI breaker is tripping at random times, sometimes every few minutes and sometimes once in 24hours. I found out that breaker is only feeding the hallway plug and not the backdoor plug, reason is I still had power to the outside plug when it tripped. Both the front and back outdoor plugs is on another GFCI breaker. My question is, if there isn't a load then what is making the breaker trip at random times? Breaker is I would say 15years old, can it be going bad? Only thing I added to the main panel last month was a dedicated line for my sewage pump for the basement bathroom. Can the neutral from that line cause the GFCI breaker to trip? Thank-you any information would much appreciated  

They do go bad. The reason you are supposed to test regularly. If it only goes to the hall, replace the breaker with a regular breaker or arc fault breaker. Option #2 is, because the receptacle is no longer a major load, combine it's wire with another bedroom/living room circuit.  

I doubt it. I think the GFCI is doing its job and it's detecting a ground fault. One reason things will trip "randomly" is when something on another circuit is activated and uses the GFCI's neutral to return its current. Your question about the dedicated "line" to the sewage pump, and the way you said it, makes me wonder if you are doing something naughty with neutral wires. Which, yeah, would trip a GFCI. Unhook the hot and neutral wires from the GFCI (leave the neutral pigtail going to the neutral bar). Leave it that way for 48 hours, if it stops tripping the GFCI is fine, it's the wires and what they're connected to.

I agree with seharper, you may have a bad GFCI. They do not trip on overload, just an imbalance between the hot and neutral. Somewhere you have a ground fault, and the GFCI is doing its job, OR you have a bad one.  

Even an overly tight box clamp or Romex staple can cause a low inductive loss from the hot leg, which will then trip a GFCI. These things must trip at a current imbalance of only 5 milli-amps and some will trip earlier. It doesn't take much to cause such a small current loss.  

Also, check neutral ground connections. An immediate trip with no load is usually due to this.  

Well 2 days later the breaker tripped. Interesting enough only thing that was different today was it rained. I'm wondering if it can be related to water getting In somewhere that's causing the breaker to trip. Sent from my SM-G935W8 using Tapatalk  

Does your outside receptacle have an "in use" bubble cover? Water could be the culprit.  

Yes they all do, however that breaker doesn't provide power to any of those plugs. Sent from my SM-G935W8 using Tapatalk

Breaker Tripping With Nothing Plugged In (Why & How to Fix)

When we think of a circuit breaker that keeps tripping, common wisdom would be that you’re dealing with a home that’s using up too much energy. So, if it’s happening to you, you might unplug some stuff. But, sometimes, the breaker just will keep tripping regardless of how much stuff you unplug. Clearly, it’s not energy consumption anymore. So, what gives?

A circuit breaker can trip when there is nothing plugged in if there is a ground fault or the circuit breaker is outdated. Damaged wires within the circuit breaker can cause it to keep tripping for no reason. The average circuit breaker lasts for 35 years, and they can trip with nothing plugged in when they are over 30 years old.

Circuit breakers are necessary to prevent electrical problems, expensive damage, and most importantly fires. It can be alarming when your circuit breaker keeps tripping when there is nothing plugged in. Follow along as we explore what it means when your circuit breaker trips for no apparent reason.

Why Would A Circuit Breaker Trip Without Anything Plugged In?

A breaker is meant to break electrical currents due to an overload, so it really shouldn’t be breaking without anything plugged in. This means that you might be dealing with an electrical issue regarding the breaker. This can be potentially dangerous, so it’s important to troubleshoot this as soon as possible, and call an electrician to fix it.

Troubleshooting Your Circuit Breaker

So, you already know that you’ve got a breaker that’s not doing what it’s supposed to do. What should you do now? The answer, clearly, is that you are gonna have to troubleshoot your circuit breaker . Here’s how to do it:

• Before anything else, check to see that you don’t have anything that could be causing the breaker to trip.  If your breaker’s tripping is related to two rooms, check to see that it’s not your DJ equipment or extra-large entertainment set up in the next room that’s causing it.
•  Check the input wires for damage.  If you notice that they’re frayed or have reason to believe that their movement is causing the breaks, call an electrician. You need to get the input wires replaced or fixed.
• Reset the breaker. Remove all connected items in your room from their plugs and reset your breaker. If it breaks again, then there is an issue that you have to fix.
• Keep an eye out for signs of a short circuit, fuse issue, or ground fault. When you’re dealing with a short circuit, you might notice a burn mark or a smell near an outlet. With a ground fault break or fuse issue, you may have a problem with wiring overheating or being exposed to water. If you believe you have an issue with this, give an electrician a call.
• If all else fails, you have a faulty breaker.  Even circuit breakers will eventually need to be replaced. They will eventually go bad. If you can’t find anything else wrong, it’s time to get a new circuit breaker. If you’ve had your circuit breaker for a very long time, it’s possible that your breaker just ran its course and needs to be replaced.

However, there are several problems that range from a ground fault to an outdated circuit breaker that you need to consider. Let’s take a look a the most common reasons that your circuit breaker keeps tripping when nothing is plugged in.

Ground Fault

A ground fault, or earth fault, is when an active wire touches the earth . Ground faults occur when a wire and the ground interact and overload the circuit breaker with the current. There is no resistance or restrictions with the earth, so an unrestricted flow of current goes through the wire and to the circuit breaker.

A ground fault is similar to a short circuit because the current bypasses the circuit wiring . The reaction from a ground fault is immediate, and the circuit will immediately flow uncontrollably. Between the lack of resistance and increased current flow, a ground fault can trip your circuit breaker and potentially damage it permanently.

Electricians treat a ground fault differently than a short circuit, but both problems require a fix. Ground faults are dangerous to fix or come into contact with, and there is potential for electrical shock.

Outdated Circuit Breaker

Circuit breakers have a lifespan just like any other key electrical fixture in your home. The average circuit breaker lasts for 35 years , but they can last for up to 40 years. You can generally tell that your circuit breaker is outdated when it acts up, and old breakers often trip when nothing is plugged in.

Worn breakers are less conductive and reliable, and they are often difficult or impossible to reset . Old circuit breakers produce a distinct burning smell that can be alarming. The voltage and current strength on an outdated circuit breaker are unpredictable and fluctuate wildly.

If your circuit breaker is nearly 30 years old and often feels hot, it is likely outdated . Replace your old circuit breaker if it frequently trips with nothing plugged in after you reset it

Old homes have different wiring configurations than modern homes, and that can affect your circuit breaker. Generally, old homes have circuit breakers that work via a single circuit. A single circuit is not enough to keep up with the electrical demands of modern homes .

Homes that are 40-50 years old or older likely have single circuit units that affect multiple outlets and even rooms. Your circuit breaker can trip even if there is nothing plugged in if you have an old home with outdated wiring and an underpowered single circuit system. The only solution, in this case, is to replace your circuit breaker and update your wiring.

Short Circuit

Similar to a ground fault, a short circuit occurs when the electrical flow goes through a short path that it wasn’t supposed to . A short circuit can easily occur if the insulation on a wire is damaged and leaves them exposed. The most common cause for a short circuit is when multiple wires become exposed and touch each other.

The current essentially takes a shortcut instead of going through the circuit wiring. Short circuits cause a massive spike in current flow that overloads the circuit breaker and causes it to trip. It is good that your circuit breaker trips during a short circuit because that can prevent expensive and harmful damage.

Lamps, electric space heaters, and plug-in appliances commonly cause short circuits. Luckily, modern devices generally have well-insulated wires to prevent short circuits. However, a short circuit can happen when nothing is plugged in because the breaker’s wires themselves can cause a short.

Damaged Wires

The wires inside of and connected to a circuit breaker are well-protected, but they can still succumb to damage. Wires are covered with insulation that can melt over time and leave them vulnerable to damage. You should be concerned if you have a damaged input wire because that can be dangerous to touch or work with .

A damaged wire can cause a current leak and your circuit breaker will trip when it recognizes it. This is a safety precaution and prevents the current from going where it shouldn’t and causing a bigger problem. It is ideal to hire a professional electrician to repair damaged wires in your circuit breaker because it is complicated and potentially dangerous.

How Much Does It Cost To Replace a Circuit Breaker?

It costs an average of $1,250 to replace an entire circuit breaker box . However, you can expect to pay $1,800 or more for an upgraded circuit breaker box, but it may be worth the added safety. Replacing single switches on a circuit breaker is much cheaper and that generally costs $45 per switch .

You can spend as little as $205 to replace an AFCI circuit breaker in some cases, but it can cost $280 or more. It is worth the cost to replace a circuit breaker because it is difficult and dangerous to replace one without professional help. However, you need to refer to local building codes if you replace your circuit breaker as a DIY project to save money.

Can You Replace A Circuit Breaker On Your Own?

Technically, most people would agree that this could be a DIY job. However, I’m a little skeptical. With electricity, working on it without much knowledge of what you’re doing is a lot like trying to shoot an arrow up in the air and hope that it won’t hit anything. You might be fine, but you might not be.

If you choose to go the DIY way, just make sure that your local building codes allow you to do this. Many cities now require all electrical work to be done through the use of a certified electrician. So, if you aren’t sure, check with your local municipal office to find out whether DIY is an option.

How long do circuit breakers last.

Circuit breakers last for an average of 35 years , but they can last for up to 40 years. You can tell that you need to replace your circuit breaker if it won’t hold a reset or you notice a burning smell coming from it. Generally, circuit breakers become less conductive when they are old and trip more often.

Why does the circuit breaker trip when lightning strikes

A circuit breaker can trip when lightning strikes because it detects the thousands of amps that come from it . The current from a lightning strike is overwhelming and would overload your home’s electrical grid. It can trip even if the lighting doesn’t touch your house because a circuit breaker can detect the current in the earth or air.
