Ground fault circuit interrupter outlets (GFCI) are fast acting circuit breakers which sense small imbalances in the circuit caused by current leakage to the ground. Should someone come in contact with a live (hot) wire, the GFCI breaker interrupts power faster than the blink of an eye (1/40 of a second) to prevent a lethal shock of electricity. GFCI outlets protect against shocks from frayed wiring, appliances and tools with hazardous leakage levels and contact with dampness while using electrical appliances. GFCI receptacle outlets could possibly prevent a majority of the electrocutions, burn and electric shock injuries and electrical fires that occur each year in and around the home.

The National Electric Code (NEC) requires the use of GFCI receptacle outlets in kitchens, bathrooms, garages, basements and near swimming pools. A GFCI should be used whenever operating electrically powered garden equipment or electric tools around the house. GFCI outlets can also be used to significantly reduce electrical hazards on construction sites.

The GFCI outlets from KK-Lite comply either with 2003 or 2006 UL requirements.
