How Long Does a GFCI Outlet Last?


GFCI Outlet

GFCI outlets and circuit breakers have been around since 1971, however, over the years have steadily been incorporated in more areas of our homes. These devices don’t last forever and eventually wear out requiring replacement.

So, how long does a GFCI outlet last? The life expectancy of a GFCI outlet is between 15 and 25 years, and a GFCI breaker can last up to 30 years. However, certain conditions may reduce the life expectancy of GFCI outlets and breakers and cause them to break in just 5 or 10 years or even less in some cases.

The exact time an outlet will last is not an exact science. Like anything else we purchase, you get what you pay for. Cheaper unbranded devices often breakdown quickly.

GFCI outlets are a staple in modern-day homes. Currently, the National Electrical Code (NEC) requires GFCI outlets to be installed in wet areas such as kitchens, bathrooms, laundry rooms, garages, and exteriors. They are considered one of the must-have safety devices in any home.

At one time, GFCI outlets were only required around sinks in bathrooms and then later in kitchens. At one time, refrigerators and washing machines were not required to have GFCI outlets, now they do.

GFCI technology has continued to advance over the years. Bad GFCI outlets are common deficiencies in home inspection reports because most people fail to routinely test them.

GFCI Life Expectancy

GFCI outlets can last a long time. It is commonly believed that they normally should last anywhere from 10 to 25 years before having to be changed.

However, as we will find out this time can vary greatly depending on a lot of different factors.

A GFCI receptacle can even go bad in just 5 years in some cases.

What Causes a GFCI Outlet to Go Bad?

Two main things may affect the condition of an outlet.

Considering these will allow you to have the right expectations about how long your GFCI outlet may last.

1. The Environment

The life expectancy will be determined a lot by the place the receptacles are installed.

GFCI protected receptacles are required by the National Electric Code (NEC) for every 125-volt 15 to 20 amps single phase outlets. Also, every receptacle within 6 feet of any kitchens, showers, and bathtubs.

They are required in these places:

  • Kitchens.
  • Laundry and other utility rooms.
  • Bathrooms.
  • Garages.
  • Outdoor locations.
  • Unfinished basements and crawl spaces.
  • Pools and spas.

GFCI outlets are usually placed in areas and rooms where there is a high risk of a ground fault happening.

Many of these can place the GFCI outlet in an environment which can expose it to a lot of water, humidity, moisture, high or low temperatures, excessive sunlight exposure, the elements, and more.

Each of these is very likely to affect the natural wear and tear of the outlet in different amounts. This will cause the GFCI outlets to not last as long as initially expected and break down sooner.

2. Usage

The other big determining factor in how long a GFCI receptacle will last is the problems it has encountered and how it has been used. This would include:

  • Overloaded electrical circuits.
  • Electrical faults.
  • Electrical surges.
  • Bad wiring.
  • Reinstallation of the receptacle in different places.

All of these and their frequency will speed up the wearing out of the outlet. And as a result, it may go bad sooner than once expected.

Also If there are any broken parts of the outlet, this too can affect its life expectancy.

How to Find out If the GFCI Outlet Has Gone Bad

It is recommended to regularly test the GFCI outlets you have installed in your home. Manufacturers are recommending that GFCI outlets be tested at least once every month.

When considering the safety of a building or a home, GFCI outlets are a must-have. This is why they are required in so many areas nowadays by the NEC.

And this is why it is recommended that we test them so often. Although they may work for many years, they may fail without giving us any signs before that. In some cases, they can even fail and not be able to trip in the presence of electrical faults or overcurrents.

Following the troubleshooting recommendations, we can make sure they are working as intended.

How to Troubleshoot a GFCI Outlet

In order to troubleshoot your outlet, you need to do a very simple test:

  • First, unplug any electrical devices that are plugged into the circuit you will be testing. Especially if you have plugged in more delicate equipment like computers, smartphones, and laptops.
  • Press the Test button on the outlet. This will cause it to trip and cut out the power to the outlet.
  • Using something small like a night lamp, test if there is any electricity running by plugging it in the outlet. It should not turn on. After that, unplug the lamp.
  • Now press the Reset button. This will restore the power to the circuit. Using the lamp method again, plug it in. The lamp should turn on.

If the GFCI fails this test, it may have gone bad in which case it needs to be replaced.

Troubleshooting a Self-Testing GFCI

The newer models of GFCI receptacles (usually the ones produced after 2015) will most likely be self-testing.

They come with a light indicator that shows if the outlet is working correctly.

  • A green indicator light is on the outlet is working as intended.
  • And if the outlet has a flashing (or solid) red light, this means that it has been compromised in a certain way.

They will still have the usually Reset and Test buttons on them so additionally, you can always manually test the outlet as well.

What Causes the GFCI Outlet to Constantly Trip?

Anyone that has had to deal with a tripping GFCI knows how annoying it can be. And I really want to stress the importance of never ignoring a GFCI outlet that constantly trips.

These devices are installed so that they offer us protection and when they trip the reason for this always needs to be investigated.

There are several reasons as to why a GFCI outlet may trip all the time:

1. Ground Fault

If there is a ground fault occurring somewhere along the electrical circuit, the GFCI will immediately detect it and trip.

2. Overloaded Electrical Circuit

Usually, the electrical circuits in our homes can be anywhere between 15 to 20 amperage.

If we plug in one too many electrical appliances to one circuit, we can easily overload it and cause the GFCI breaker to trip. The GFCI receptacle does that in order to prevent any damage from overheating.

Also, faulty or malfunctioning electrical tools, appliances, and devices can also cause an electrical overload.

3. A Bad GFCI Outlet

We can expect a reasonably long service from our GFCI outlets. However, the above mentioned 25 years are not set in stone.

The environmental conditions, any electrical surges and faults, any natural wear and tear, and more can influence and cause a GFCI outlet to go bad sooner than expected.

This is why we need to make sure to always keep an eye on the receptacles in our homes.

A faulty GFCi outlet may constantly trip or even trip in an open position where the electrical current continues to flow.

4. The GFCI Is Subjected to Moisture

GFCI receptacles are used in such environments (in kitchens, and outside areas, for example) that can easily lead to the receptacles being subjected to more than the normal levels of moisture.

Moisture accumulation is hazardous and can cause different electrical faults that will cause the outlet to trip in order to prevent any electrical hazards.

5. Bad Wiring

Bad wiring can also cause the receptacles to trip more frequently than necessary.

Also, the presence of a ground fault in any electrical circuits that are found nearby can be detected by the GFCI receptacle and trip despite its circuit not being affected.

6. Appliances

Some electrical appliances like freezers and refrigerators have been known to cause GFCI outlets to trip frequently.

How to Have Your GFCI Outlet Last Longer

There are several simple steps you can make to have your outlet last for as long as possible.

  • Don’t unplug electrical devices by pulling on the cord as this can detach the outlet from the wall.
  • Create a habit of switching off devices that you are not using.
  • Do not overload the GFCI receptacle by plugging in high-demanding electrical appliances or using power strips.
  • Have the wiring inspected in order to confirm it is up to code, and no bad wiring practices have been used.
  • Avoid exposing the receptacle to water, chemicals, UV light, etc.
