GFCI (Ground-Fault Circuit Interrupter)
An electrical safety device that interrupts a circuit when it detects current leaking to ground, required by NEC in wet locations.
What gfci (ground-fault circuit interrupter) actually means.
GFCI protection is required by the National Electrical Code in residential bathrooms, kitchens (counter-area receptacles), garages, outdoor receptacles, basements, laundry areas, and pool equipment. NEC 2023 expanded GFCI coverage significantly vs. earlier code cycles, so existing homes commonly need GFCI upgrades during remodels. GFCI breakers protect entire circuits; GFCI receptacles protect the receptacle and downstream loads.
