What is a GFCI Outlet?

A GFCI (Ground Fault Circuit Interrupter) outlet, sometimes referred to as a gfci receptacle, is a device designed to protect you from electrical shock. These outlets constantly monitor the flow of electricity and detect any imbalances, such as ground faults, where electricity flows outside its intended path.

How GFCI Outlets Work

But how does a GFCI outlet save you from a hair-raising experience? When this trusty device detects a ground fault, it trips the circuit and cuts off power in a flash, preventing potential electrical shock. Keep in mind that the magic happens behind the scenes, as GFCI outlets work by comparing the input current on the hot side to the output current on the neutral side. If there’s even a slight imbalance, the outlet takes action and disconnects the power.

GFCI Outlet Safety Features

You might be wondering, what sets a GFCI outlet apart from regular outlets? For starters, GFCI outlets are genius at providing extra safety in high-risk areas like kitchens, bathrooms, and outdoor areas. In fact, they’re required by code for microwaves and other appliances near water sources, thanks to their impeccable response time and ability to prevent electrical shock at the source.
