What is a GFCI?
A GFCI is a special type of outlet designed to cut off power before a deadly electrical shock can occur.
How does a GFCI work?
For example, when you plug in an appliance like a hairdryer energy flows from the outlet to the device. A GFCI monitors that amount of electricity if there’s any leakage or interruption of that current, such as when the hairdryer comes in contact with water, the GFCI cuts power to the device in as quickly as one 30th of a second before a deadly shock can occur.
How do you tell if a GFCI is working?
The GFCI shuts down power being fed to the current that would have caused harm to the user, preventing serious injury from taking place. You can always tell them apart from normal outlets because the receptacles will have two rectangular-shaped buttons somewhere on the front of the outlet. These buttons will have the words “reset” on one and “test” on the other. Furthermore, although colors are not always displayed on them, they are oftentimes color coded: Red for reset, and black for a test.

A standard household outlet features two, three-prong plug-in slots, while a GFCI outlet features the same plug-in configuration plus two buttons on its face: a “TEST” button and a “RESET” button. The rules requiring the installation of the GFCI outlets in new construction has expanded over the years to include more applicable locations:
How should I care for GFCI outlets?
Once installed, a GFCI outlet needs virtually no additional care, although you might want to press the Test button once a month or so to make sure it’s still functioning properly. Occasionally, a GFCI will shut itself off for no apparent reason—known as “nuisance trips” or “ghost trips.” This can be caused by something as simple as static electricity or nearby lightning. When this happens, just press the Reset button to restore electricity.
How many wires are needed to replace an outlet?
The other caveat is that only outlets connected to three wires are suitable for DIY replacement. Outlets with three attached wires (remove the outlet plate to determine the number of attached wires) indicate that the outlet is located at the end of an electrical circuit (a wiring loop that starts and finishes at the breaker panel). An outlet with five attached wires is located in the middle of an electric circuit, and the wiring process is more complicated—only a licensed electrician should replace those outlets.
What happens if a GFCI trips frequently?
If a GFCI trips frequently when not in use (daily or weekly), the outlet itself could be worn out or faulty and should be replaced.
How to shut off power to outlet?
