What happens when a GFCI fails?

If the GFCI's internal current transformer senses more than a 4-5 milliamp loss, it instantly shuts down the outlet and any outlets it feeds to prevent accidental electrocution. Most often, when a GFCI “trips” it is the result of a faulty appliance plugged into the outlet or an outlet down circuit.

Why would a GFCI trip with no load on it?

A Loose Wire in an Outlet This wiring problem can be maddening. In short, one of your outlets has a loose wire that is causing your breaker to trip and will continue to do so until it's replaced. This is a somewhat common problem if you have an outlet with a GFCI (Ground-Fault Circuit Interrupter).

Perhaps power is out in one room, and the breaker is not tripped, but the electrical socket is not working. The next step is to take the outlet out of the box and check for any loose connections. There are three main types of loose connections to look for when one outlet is not working: Loose terminal screws.

What happens if a GFCI is wired incorrectly?

If you miswired the GFCI it may not prevent personal injury or death due to a ground fault (electrical shock). If you mistakenly connect the LINE wires to the LOAD terminals, the GFCI will not reset and will not provide power to either the GFCI receptacle face or any receptacles fed from the GFCI.

What causes a GFCI to trip repeatedly?

The usual suspects for ground-faults include worn insulation, conductive dusts, water, or other "soft grounds." Ground faults account for more than 80% of equipment short circuits and in 90% of those cases it is caused by insulation deterioration on wires and cables.

How do I know if my GFCI is good?

Push the TEST button on the GFCI. The GFCI should trip, stopping the flow of electricity to the lamp. Note that the RESET button will pop-out. If the lamp doesn't turn off when the TEST button is pushed, the GFCI is not working properly and should be replaced immediately.

Will a GFCI outlet reset without power?

The outlet may have dust or moisture inside, you have a bad electrical connection, or there is an improper connection. If there is no power supply to the outlet, your GFCI will not reset. While 99% of outlets not resetting are due to ground faults and wrong connection problems, GFCI outlets can still go bad.

When should I replace GFCI outlet?

Most GFCI outlets will last for about 15 to 25 years, but in certain circumstances, they can fail after 5 years.

How do I stop my GFCI tripping?

Unplug all appliances on that outlet's circuit.
Push the reset button.
Plug in one appliance at a time until the GFCI trips.
