A ground fault circuit interrupter (GFCI) is an outlet with the ability to cancel incoming electrical current, which effectively blocks shocks from devices and storms. An electrician should install GFCIs to ensure they’re up to local and federal codes. Learn more about how GFCIs work and where they’re needed in the home to get the most out of their installation.

How a GFCI Works

A GFCI constantly looks for any change in current. If it detects any, it shuts the current off. If an appliance falls into water, for example, there is an increase in current, so the GFCI cuts the power. An electrical appliance with a bad wire can also deliver a shock, which a GFCI can minimize.

In conjunction with fuse boxes, a GFCI reduces the chances of electrical fires. It will also cut power if smaller leaks of current occur, which can protect your computer or other expensive appliances from burning out.

Where Should They Go?

Any outlets near water should have a GFCI installed by an electrician. Federal law states that they should be within eight feet of a water source, but local laws may be more stringent. All outdoor outlets and temporary wiring for construction and renovation projects should have GFCIs too.

Recently adopted legislation requires homeowners to have GFCIs in nearly every room, as well as outdoors, and many homes often include GFCI breakers to maintain all the wiring.
