A ground-fault circuit interrupter (GFCI) detects leaking electrical current and quickly cuts power to help reduce shock risk.
GFCI protection can come from a receptacle, a circuit breaker, or a portable plug-in device.
One GFCI receptacle can protect additional outlets on the same circuit when they are connected to its protected load terminals.
Test GFCIs every month using their TEST button, following the manufacturer’s instructions. Confirm that power switches off before pressing RESET to restore it.
If your home lacks GFCI protection around areas such as bathrooms, kitchens, garages, or basements, ask a qualified electrician about adding it.
Keep electrical appliances away from sinks and bathtubs. GFCI protection reduces risk, but a shock can still occur before the device disconnects power.
