GFCI - Ground Fault Circuit Interrupters | Best Pick Reports
Ground fault circuit interrupters (GFCIs), designed to prevent
people from receiving electrical shocks, can be installed at an
individual outlet or in the service panel. When properly installed in a
circuit, a GFCI continuously monitors the current flowing in both lines
in the circuit. If the GFCI detects a short circuit developing, it
quickly interrupts the circuit before anyone is seriously injured. GFCI
protection is provided either by special GFCI outlets or by special
GFCI circuit breakers. Depending on how a GFCI outlet is wired, it may
protect either that outlet only or all the outlets downstream from it.
GFCI circuit breakers protect the entire circuit. The National Electric
Code requires GFCI protection on all new outlets located outside of the
house, in bathrooms, in garages, in basements, and in kitchens. GFCI
outlets have two buttons on the face, one labeled “test” and one
labeled “reset.” Both GFCI outlets and GFCI circuit breakers should be
tested often to ensure proper function.
