What is a GFCI Outlet? (with photos)

GFCI outlets can reduce the risk of fire in an electrical house.

A GFCI outlet is an electrical outlet designed to protect people from fatal electrical shock. In addition to preventing electrocution, GFCI outlets can also reduce the risk of home fires caused by electrical problems and reduce damage to appliances caused by faulty electrical circuits. These outlets use Ground Fault Circuit Interrupter (GFCI or GFI) technology; it is also possible to install a GFCI in the breaker box or use a portable GFCI device.

Any electrician should be able to install GFCI outlets.

The way these channels work is quite ingenious. The GFCI output monitors the flow of power through the circuit. If an imbalance occurs between the “hot” and “neutral” poles in the circuit, indicating that there is a ground fault, the output trips. Ground faults can be caused by a wide variety of things, including a human touching a live part of the circuit, and this can be deadly. A classic example of a ground fault that has been used as a plot device in several films is a hair dryer that falls into the bathtub, turning the bathtub water into part of the electrical circuit and electrocuting the hapless occupant.

GFCI circuits can be installed in the breaker box or in the outlet itself.

The design of a GFCI socket includes two small buttons labeled “test” and “reset”. People with GFCI outlets should get in the habit of testing them regularly to confirm they are working properly. This can be done by plugging a lamp into the outlet, turning the lamp on and pressing the test button. The light bulb should go out and the reset button should pop out, allowing people to plug it back in.

People with electrical wiring experience can install GFCI outlets.

GFCI outlets are required by law in many regions of the world in locations such as bathrooms, garages, kitchens, crawl spaces, unfinished basements and outdoor outlets. Although people are encouraged to install them everywhere for safety, these areas are the places of greatest concern because they are prone to the development of ground faults. Any electrician should be able to install GFCI outlets and people with electrical wiring experience can install them as well.

If a GFCI electrical outlet is unplugged, people should check why the outlet has cut the power supply before restarting it. For example, if a kitchen outlet suddenly stops working, it could be because a wire inside the outlet is coming in contact with something that is causing a ground fault, which means people are not necessarily aware of the fault. An electrician can run diagnostics to determine why the outlet was disconnected and reset or replace the outlet as needed.

People should be aware that they can still be shocked by a ground fault associated with a GFCI outlet. The outlet will detect the power imbalance quickly enough to avoid a serious or fatal shock, but the victim will still receive a shock in the fraction of a second it takes for a GFCI outlet to respond to a ground fault.
