Ground Fault Circuit Interrupter (GFCI)

In Plain English

A safety outlet or breaker that instantly shuts off power if electricity starts leaking — protecting people from electrocution near water.

Definition

A fast-acting electrical device that detects ground faults — current leaking outside the normal circuit path — and shuts off power within milliseconds to prevent electric shock. GFCIs are required by the NEC in bathrooms, kitchens, garages, outdoors, and other wet or damp locations. They can be installed as receptacles or breakers.

Example

All exterior and bathroom receptacles were upgraded to GFCI protection during the code compliance inspection.
