Ground Fault Circuit Interrupter Gfci Protection

Ground fault circuit interrupters gfcis or gfis are safety devices built into outlets that protect against electrical shock.

Ground fault circuit interrupter gfci protection.

Their circuitry monitors electrical input. Ground fault circuit interrupters or gfcis are life saving devices found on electrical receptacles outlets circuit breakers extension cords and other electrical equipment they detect imbalances in the electrical current and quickly shut off the power to minimize the risk of shock. At first it was only required for swimming pools and then expanded to outdoor and bathroom receptacle outlets. The ground fault circuit interrupter or gfci is a fast acting circuit breaker designed to shut off electric power in the event of a ground fault within as little as 1 40 of a second.

A gfci is a ground fault circuit interrupter an inexpensive electrical device that if installed in household branch circuits could prevent more than two thirds of the approximately 300 electrocutions still occurring each year in and around the home. When a ground fault occurs the gfci quickly in a fraction of a second shuts off the power. If a person s body starts to receive a shock the gfci senses this and cuts off the power before he she can get injured. Ground fault circuit interrupter also detects ground faults and interrupts the flow of electric current.

Gfcis are generally installed where electrical circuits may accidentally come into contact with water. A gfci not to be confused with an afci integrates a ground fault protection in receptacles where electrical equipment is near water or might be in contact with water. Ground fault circuit interrupter protection gfci it s rather remarkable when you stop to think about it. A grounding type receptacle if gfci protected and marked gfci protected and no equipment ground the equipment grounding conductor plays no part in the operation of a gfci so it will provide ground fault protection even on a 2 wire circuit without an equipment grounding conductor.

A residual current device rcd residual current circuit breaker rccb or ground fault circuit interrupter gfci is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock. A ground fault circuit interrupter gfci can help prevent electrocution. A ground fault circuit breaker is properly called a ground fault circuit interrupter breaker or simply a gfci breaker it installs into a home s service panel or breaker box and provides gfci protection for the entire branch circuit it serves.
