Ground Fault Circuit Interruption is an electrical safety feature required by the NEC (National Electric
Code) in certain areas in and around your home to prevent protentional shock hazards. GFCI protection
is required near areas of water and unfinished areas of your home like kitchens, bathrooms, basements,
and your home's exterior. GFCI protection devices measure an imbalance between your power and
neutral (return path) wires. If it senses an imbalance, the device will trip to prevent the potential of an
individual being shocked.
