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.

Understanding GFCI Nuisances

January 24, 2019

Since the expansion of the 2017 National Electrical Code (NEC) ground fault circuit interrupter (GFCI) requirements to include single-phase receptacles up to 50A and three-phase receptacles up to 100A, we’ve seen a trend of increased GFCI nuisance tripping. While these trips can be frustrating, it’s important to not create a code violation or put personnel at risk by removing GFCI protection. Often, a tripping GFCI device may be operating properly; it’s possible there is an equipment or wiring issue that needs to be addressed.

At Henderson Engineers, we’ve compiled the following information to help our clients understand why they may be experiencing an issue and suggestions on how to address it.

What is GFCI protection?

GFCI devices have been credited with saving numerous lives since their introduction to the NEC in 1971. This protection can be achieved via a GFCI circuit breaker or a GFCI receptacle. These devices reduce electrocution risks by measuring the electrical current between the phase conductor and the neutral return. If the return current differs by more than 4 to 6 mA, a dangerous amount of current is flowing somewhere it shouldn’t be – so the device shuts off. Per the 2017 NEC, GFCI protection is required in bathrooms, kitchens, rooftops, outdoors, within 6’ of a sink, and select other areas.

The NEC commentary explains that they expanded GFCI requirements to include higher voltages and current ratings because equipment connected to those receptacles present the same shock hazards as those of lower voltages and current ratings. Unfortunately, this expansion of the GFCI requirements has led to more nuisance tripping and owner’s asking, “Why is my GFCI not working?”

Common Causes of GFCI Trips

1. There are too many appliances being protected by the GFCI.

Sometimes tripping occurs when a GFCI circuit breaker is protecting multiple downstream receptacles. If several appliances are connected to the GFCI device, the cumulative effect of the appliance leakage currents may trip the GFCI. To ensure proper operation, minimize the number of appliances protected by the GFCI. Depending on the circuit length from the GFCI sensing device, it may be necessary to limit the number of appliances being protected to one or two.

2. The circuit is too long for the equipment being protected by the GFCI. 

This is common in GFCI circuit breakers with circuit lengths over 150’. Capacitive leakages due to the wire length of the circuitry may exceed the threshold of the GFCI. (The actual length limitations vary depending on wire type and size.) To prevent this issue, place the GFCI device close to the equipment it will be protecting – this may mean using a GFCI receptacle or blank face GFCI device near a normal receptacle.

3. The GFCI was improperly wired by an electrician.

Have the installation checked to see if the GFCI receptacle and related circuitry are installed correctly. Verify the neutral is dedicated and connected to the correct circuit, etc. While testing of GFCI devices is not generally included in the basic scope of commissioning services, having a trusted third-party electrician or commissioning agent provide independent verification of proper installation may be necessary.

4. The area is too wet. 

If nuisance tripping is occurring in areas near dishwashing, mop sink, janitorial, ice machines, showers, walk-in coolers, exterior locations, roofs, and other areas with a lot of condensation, then too much moisture may be the cause. Check to see if there are any environmental or operational changes that can be made to reduce moisture near the appliance and receptacle. Installing a weatherproof cover plate at the receptacle may be helpful.

5. An appliance may have manufacturing defects. 

It’s possible an appliance may be leaking too much current to ground. Appliances are allowed a certain amount of leakage current per their UL listings; acceptable maximums may be as high as .75mA per appliance. Unfortunately, some equipment may not be built to the same standards as the prototype that passed testing. Now that more receptacles are required to have GFCI protection, equipment issues may be coming to light. If you have faulty equipment, contact the equipment supplier/manufacturer for repair or replacement.

6. The GFCI device may be defective. 

These devices don’t last forever, and some are defective even when new. UL 943 covers Class A GFCI devices. GFCI breakers and receptacles should be replaced in accordance with manufacturer’s recommendations. Best practice is to test GFCIs monthly and replace them every 5 years.

Best Practices

GFCI devices trip for several reasons. The following best practices can help confirm proper operation and reduce nuisance tripping.

• Minimize the number of appliances protected by each GFCI.
• Minimize the circuit length from the GFCI circuit breaker to the receptacle – a maximum conductor length of 150’ is good rule of thumb.
• Verify GFCIs are installed per manufacturer’s recommendations and as required per code.
• Avoid excessive moisture around appliances and receptacle.
• Replace defective appliances.
• Replace defective or GFCI devices that are more than 5 years old.
• Maintain easy access to GFCI devices in case they need to be reset. (The 2017 NEC requires GFCI receptacles to be “Readily Accessible.” That means one must be able to reach the device quickly, without having to use ladders or climbing over obstacles, like large stationary kitchen equipment. GFCI breakers or blank face GFCI devices are sometimes needed to meet this requirement.)

Although they can be frustrating, it’s important to remember, GFCI devices have been proven to save lives and are required by code. Proper application and maintenance of these devices is essential for personnel safety and smooth business operations.

Troubleshooting GFCI Outlets: How to Stop Them from Tripping

Mar 28, 2023

Filed under : GFCIs

Are you tired of dealing with tripping GFCI outlets? We've all been there. You're using your favorite electronic device, and suddenly, the outlet trips. It can be frustrating, especially when you're in the middle of something important. But don't worry, we're here to help! In this article, we'll go over everything you need to know about GFCI outlets and how to troubleshoot them when they trip.

Table of Contents

What is a gfci outlet, why do gfci outlets trip, how to troubleshoot gfci outlets, how to reset a tripped gfci outlet, when to replace a gfci outlet, tips for preventing gfci outlets from tripping.

Before we dive into troubleshooting GFCI outlets, let's first discuss what they are. GFCI stands for Ground Fault Circuit Interrupter, and it's a type of electrical outlet that's designed to protect you from electrical shocks.

A GFCI outlet works by constantly monitoring the flow of electricity through the circuit. If it detects any imbalance in the current, such as when electricity is flowing through your body instead of the circuit, it quickly shuts off the power.

There are several reasons why GFCI outlets can trip, including:

• A ground fault: This is when electricity is flowing through a path other than the intended circuit. For example, if you touch a live wire while standing in water, the electricity will flow through your body and create a ground fault.
• Overloading: If you have too many devices plugged into one circuit, it can overload the circuit and cause the GFCI outlet to trip.
• Faulty wiring: If the wiring in your home is old or damaged, it can cause the GFCI outlet to trip.

If your GFCI outlet is tripping, there are a few things you can do to troubleshoot the problem. Here's a step-by-step guide:

Unplug all devices from the GFCI outlet: This will help you determine if the problem is due to an overload.

Press the "test" button: This will simulate a ground fault and trip the outlet.

Press the "reset" button: If the outlet doesn't reset, it may be faulty, and you'll need to replace it.

Check the circuit breaker: If the circuit breaker has tripped, you'll need to reset it.

Inspect the wiring: Check the wiring for any damage or signs of wear and tear. If you find any issues, call a licensed electrician to fix them.

If your GFCI outlet has tripped, here's how to reset it:

Unplug all devices from the outlet.

Press the "reset" button: This will restore power to the outlet.

Plug in your devices one at a time: If the outlet trips again, it may be overloaded, or there may be a fault in the device you're plugging in.

If the outlet keeps tripping, it may be faulty, and you'll need to replace it.

If you've tried troubleshooting your GFCI outlet, and it still keeps tripping, it may be time to replace it. Here are some signs that your GFCI outlet needs to be replaced:

• It trips frequently, even when there's no overload or ground fault.
• The outlet is old and worn out.
• The outlet is damaged or broken.

If you're not comfortable replacing the outlet yourself, it's best to call a licensed electrician to do the job.

While GFCI outlets are designed to protect you, they can be frustrating when they trip. Here are some tips for preventing GFCI outlets from tripping:

• Don't overload circuits: Be mindful of how many devices you're plugging into one circuit.
• Use GFCI outlets in wet areas: GFCI outlets are essential in areas like bathrooms, kitchens, and outdoor spaces where there's a risk of electric shock.
• Keep outlets away from water: Water and electricity don't mix, so keep outlets away from water sources like sinks and showers.
• Test your GFCI outlets regularly: Press the "test" button on your GFCI outlets at least once a month to make sure they're working correctly.
• Call a licensed electrician for any wiring issues: If you notice any wiring issues in your home, call a licensed electrician to fix them.

GFCI outlets are an essential safety feature in any home, but they can be frustrating when they trip. By following the troubleshooting steps outlined in this article, you can quickly identify and fix any issues with your GFCI outlets. Remember to always prioritize safety, and if you're not comfortable working with electricity, call a licensed electrician.

• GFCI stands for Ground Fault Circuit Interrupter.
• GFCI outlets can trip due to a ground fault, overloading, or faulty wiring.
• Unplug all devices from the outlet, press the "reset" button, and plug in your devices one at a time.
• You should replace a GFCI outlet if it trips frequently, is old and worn out, or is damaged or broken.
• Don't overload circuits, use GFCI outlets in wet areas, keep outlets away from water, test your GFCI outlets regularly, and call a licensed electrician for any wiring issues.

How to diagnose intermittent tripping of GFCI breaker

• JJ Contact options for registered users
• posted 12 years ago Mon, Aug 1, 2011 4:11 PM

we have a GFCI breaker in our breaker box. On that circuit are the lights and outlets in two bathrooms and the garage door opener. I'm not sure if anything else is on the circuit.

Intermittently, the breaker has been tripping (usually in the middle of the night or when we are at work during the day). When I reset the breaker, it stays on. This has recently been happening on a frequency of between twice per day to once every few days. At night we have a night light on in one bathroom, but during day I can't think of anything on this circuit that would be drawing a current

One time it tripped when I was actually at home, and I found that when I tried to reset the breaker that it would immediately (within a second or two) trip again - but after about 10 minutes I was able to reset it and it stayed.

I'm not sure how to diagnose the cause of this problem if whatever is causing the short will not stay shorted.

There used to be two outdoor outlets on the circuit - but I discovered that whenever we had a hard rain, moisture would get into those boxes (which were no longer well sealed) and cause the breaker to trip - it could not be reset until the moisture was gone. Those outlets have since been removed, so are not the cause of the current problem.

Also, this has been happening recently during a period of bone-dry weather.

Any help on how to diagnose this problem and resolve it greatly appreciated.

Mice can be the cause.

Without a megohm meter, the best way to go is to split the circuit in two. Open a box and disconnect half of the outlets. If the problem stops, then it is farther down the line. If it persists, the problem is up the line.

With the breaker tripped it is pretty easy to figure what is on the circuit.

It could be that the breaker is going bad. If you have two GFI breakers in the box you can switch the circuits. This will tell you if it is the breaker or the wiring.

That sounds like a strange setup. It sounds like something that was done in the late 70's early 80's. I would kill the breaker and determine what receptacle outlets are on that circuit, paying special attention to outside outlets, basement outlets, garage outlets and bathroom outlets. Once you determine what's on the circuit, I would replace the breaker with a standard breaker, and install GFCI receptacles in all the locations where they are currently required. This would include the bathroom outlets, but only the receptacles, not the lights, outside receptacles, basement, and all garage receptacles, that were on that circuit. Once that's done, it'll be clear where the problem is,or was.

I had a similar problem with a GFCI breaker in an outdoor panel. As far as I know, ants were the culprit. No problem after I sprayed bug killer on the breaker panel. The house was built in 1980, when GFCIs were first required and expensive. If the problem persists, you may want to consider replacing the breaker with a standard one and replace outlet(s) on the circuit with GFCI outlets to offer continued safety. Multiple GFCIs will also also save you from having dead outlets in the bathrooms just because an exterior outlet got wet from rain.

• posted 12 years ago Tue, Aug 2, 2011 3:52 PM

Good deduction. The house was built in '77.

Thanks for all the replies.

It occurred to me that the garage outlets are also on the circuit and the problem could be there too.

One difficulty with unplugging stuff (not much stuff actually plugged in to the affected outlets) and waiting is that that can only tell you what is not the problem - if it circuit trips with a device unplugged, you know that device it's not the culprit (unless there is more than one culprit). Waiting a day or two with a device unplugged may not be long enough to establish the device as the culprit - sometimes the circuit can trip just a few hours, but sometimes it will be fine for several days.

Perhaps I will go ahead and replace the breaker with a standard breaker and replace all the outlets with GFCI outlets. One problem is that one bathroom has a light fixture with an integrated outlet (for shavers). I guess I could just disconnect the outlet on that fixture though (it never gets used anyway).

Mice and ants were mentioned as possible culprits. I'm not sure how you mean? I could see mice chewing through wiring and leaving wires exposed - which could then short - but wouldn't that be more of a continuous problem? Can ants chew through wiring to? Or is there another way these pests could be causing a short?

My house was wired the same way with a 15amp GFCI breaker.. If wife and daughter were both using their blow dryers it would trip the breaker every time. I replaced the 15 amp GFCI breaker with a 20 NON GFCI unit. Installed GFCI outlets in the bathrooms and put the garage on a separate circuit with a 20 A GFCI breaker. Used the old 15 A GFCI to run a circuit for the freezer in the garage about a year later as it was causing trip when I used my power saws.

I've had to replace GFCI outlets at swimming pools, where tiny ants literally crawl inside the device and nest. Ultimately it destroys the device

• posted 12 years ago Tue, Aug 2, 2011 8:48 PM

You don't want to replace a 15 amp (gfci) breaker with a 20 amp breaker, unless the wire is 12 gauge.

GFCI intermittent nuisance trips

• Add to quote

Okay, first off I would like to state that I am not a electrician, an electronic technician perhaps, but when it comes to AC I am as lost as a ball in tall grass. I would also like to state that I believe that I understand the fundamentals of a GFCI breaker , it is looking for a difference in current on the common (neutral, white) and the hot (power, black) wires and a variance over 5 milliamperes will cause the GFCI to trip. This is usually a result from a ground fault, which may or may not include the actual earth ground, but is usually a faulty connection somewhere in the common run, caused by moisture or even a bad spot in the insulation due to inadequate precautions while installing (usually). The reason that I wanted to put all that first is due to my conducting several tedious hours researching my problem and discovering that most of the replies covered to some degree and on occasion disputed the above mentioned items, but what you see is what I have come to be most correct . I have not found any scenarios that were close enough to my situation that I felt comfortable in proceeding with any corrective actions. Whew! Okay, my dad and I recently built a screened in porch on the back of his mobile home. This mobile home is over twenty years old, but well maintained and no major issues. After I did the structural engineering portion and designed the decking and roof system, my dad assisted in the construction. He decided to wire three electrical outlets, a ceiling fan and four dual four foot fluorescent lights. Now he has done some DIY wiring in the past for his shop located adjacent to the mobile home. He checked the outlets with one of those three pronged testers, two amber lights indicating correct wiring, polarity okay and good ground. The ceiling fan works fine, as do the outlets. The porch is wired to a male three pronged standard plug and plugged into an outlet that is wired on a breaker in the main junction box. He decided to use the plug setup until he was confident there were not wiring issues, then he intends to hard wire the porch to a breaker inside the main junction box. Now here is where it gets mind boggling. He has a GFCI breaker inside the mobile home that is wired to both bathrooms and the external outlet at the far end of the house. Well it seems that the GFCI trips on a whim. We replaced the outlet outside thinking that there may be a moisture problem, but the problem persisted. By happen-chance, I discovered that the GFCI breaker is tripping only when the fluorescent lights are switched on AND not every time. The lamps have electric start ballasts, for low temperature operation, therefore I hypothesised that perhaps there is some inductance during the initial powering up of the lights, even though they are on a different circuit. I have been able to reliably reproduce this anomaly by having all four lights switched on at their individual factory pull switches and then flipping the wall switch that he wired them to. He mistakenly got two three-way switches, one for the lights and one for the fan. He has 3-14 romex coming into the porch, wired to an outlet then split with one run for the other two outlets and the other run split again with one run going to the switch and the celing fan. The other run goes to the switch, then he split the run again, one for one side of the porch lights and the other run for the other side with two light fixtures with two tubes each for a total of four 40W four foot lights off of each run. Well I think I have successfully convoluted this topic to the point to where I may need psychotherapy. I thank any and all for taking the time to read this far and I will be anxiously be anticipating comments. God bless. ~~Joey~~  

I hate DIY GFI problems, way to easy for to many mistakes, I would meg the wire and find the fault.

Stubbie said: Hello Joey A couple comments.. Fluorescent are often the cause of intermittent tripping gfci's. However the gfci breaker is not part of the circuit from which the porch lighting is supplied. I'm assuming that other appliances can be plugged into this outlet the porch is supplied from and the gfci will not trip.....only trips when you turn on the porch fluorescents? ..and you are positive this gfci breaker is not part of the outlet the porch is plugged into? Click to expand...

jejm1975, Hmm, seems like you've got yourself quite the problem. I can't say why the GFCI is tripping. What you could do is replace the GFCI breaker with a regular breaker and change the first outlet in the "stream" to a GFI outlet; hot pair (from the panel) to the the line side and the remainder of the circuit to the load side. See if that "solves" your problem. Is the GCFI and the fluor. lights on the same bus in the panel? Perhaps some sort of inductance there causing the breaker to trip. I'm not an EE, just an ET and electrician. Like they used to say about frequency modulation, it's "FM" feakin' magic....

Since this is a GFCI breaker , the problem could simply be an overcurrent issue. While the OP's understanding of GFCI's seems to be solid, I, like Chris, find the GFCI issues posted herein to be somewhat annoying. With GF's, there can be a zillion reasons for the tripping and it's very tough to shoot this type of trouble online. BTW, I have several 32W 2-bulb FL fixtures in my basement which are powered from a GFCI breaker (and yes, I understand that it is not required however when I installed the lights, it was the only type of breaker that I had on hand). 2 years later, I have not suffered one nuisance trip. Done  

Is it possible that there is a crossed neutral or two neutral paths for the florescent light fixture? Even though the light is fed from the non GFCI circuit, if some of the juice can get to the neutral wire on the GFCI circuit it will sense an imbalance and trip. About the only other thing I can think of is if there is a "ground loop" (or in this case a Neutral or Hot loop). If you have a loop of wire it can be susceptible to nearby electrical interference (transformers intentionally use this to step up/down voltage). The Florescent light may induce a small current/voltage in an adjacent loop and if that loop happens to be on the GFCI circuit... bang there goes the circuit. My money would be on the first one, but the solution to both is the same: Make sure there is one and only one path for the electricity to take on all circuits at any time.

I'm not a professional but trying to follow along here but when did multiple panels come into play? Can't believe there is more than one for a mobil home. Thought this was plugged into an existing circuit of the main panel??

Ok it would seem to me that the fluorescents are causing the problem like it or not. IMO the problem has to be emi/rf induced into the electrical system from the ballasts of the light fixtures. You might check to see if one of the lights is slow to start (light) on occassion. This may be the source of the intermittant tripping gfci. A discussion on emi and rf nuisance tripping would entail many pages so I think best to isolate the problem to the fluorescents. Asuming that all current carriers connections are proper and isolated from grounded metal and each other. I doubt you have a fire hazard assuming you agree that the wiring is correct for the porch. My suggestion would be to run an extension cord from other outlets and plug the porch into those and see if it still trips that gfci. I would include the bathroom receptacle on the gfci circuit. I would also be sure this gfci breaker is not old school and is of the newer type with improved circuitry for interference from emi/rf and the fluorescent ballasts should have THD of less than 10%. Electronic ballasts are the most unstable and can emit rf in large doses if not shielded properly. You will see this in the cheapo light fixtures. My understanding is that these are no longer UL listed so probably is not your problem.You might even have to resort to new fixtures that are incandescent or better quality magnetic ballast fluorescents if the ones you have now a cheapos.

Can you describe how the fluorescent lights are wired? You stated the porch was wired with receptacles, ceiling fan, and fluorescent lights, and that the porch is for now powered by using plug and cord at a GFCI protected outside receptacle. You also stated you used 14/3 to do this. I am having a hard time figuring out how this is wired, and how the lights could keep working in this scenario.

Yeah that's a good point...I considered that he meant 14/2 with ground.  

This would be the typical service to the mobile home having an outside 3 wire service rated pedestal (main) and a 4 wire service entrance feeder to the internal panel (sub-panel). The porch appears to be plugged into a receptacle on an outside wall of the porch and then that receptacle is plugged into one coming off the service panel?

There are so many code violations and probable/possible miswires there, I don't know where to begin... I'll have to study those pix some more and get a few more sheets of paper to keep track...  

Not trying to be cruel, but that has to be about the worst wiring job I've seen.........ever!!!! Pull the pictures off the web immediately before someone else sees them........ I'm serious as hell!  

Hello Joey Thought I would stop back in and just say that is not the worst wiring that Silk has ever seen...he probably forgot to take his medication yesterday...:whistling2: Humor aside don't replace the gfci breaker that is not your problem. And the fixtures are fine those are not the type I was referring. It appears you have a cable running from the old porch light box to the new flood light box. Is that flood light on the gfci breaker circuit that is tripping? Remember the neutral wire is not switched but is monitored by the gfci breaker..... EDIT: Might as well go out in left field and give you my thoughts. When you plug the porch into the gfci circuit you get an immediate trip of the gfci. This tells me your dad has a neutral to ground fault in his wiring splices somewhere, generally a hot wire to ground will trip the circuit breaker on the the branch circuit being served. Odds are a neutral to ground fault. Second that cable to the flood lights splits the fluorescents and if there is an rf/emi issue that is where its likely coming from with your intermittant problem. So in my opinion you have 2 issues a wiring fault in the circuit to the fluorescents causing the instant trip of the gfci and a possible rf/emi issue occuring in the cable to the flood lights.  

Stubbie said: Hello Joey Thought I would stop back in and just say that is not the worst wiring that Silk has ever seen...he probably forgot to take his medication yesterday...:whistling2: . Click to expand...

I agree with Chris and Stubbie. I would be looking for a wiring error. A ground touching a neutral somewhere. In your pictures I am seeing to many code violations and wiring errors to even start listing them. I seriously think you need an electrician to come in and do entire job correctly.  

Okay, since no one else is going to ask, what is up with all the taped splices?  

I kind of like the wire going into the water pipe.
