Ground Fault Circuit Interrupter Gfci Protection

Their circuitry monitors electrical input.

Ground fault circuit interrupter gfci protection.

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 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. Ground fault circuit interrupter protection gfci it s rather remarkable when you stop to think about it. Ground fault circuit interrupter also detects ground faults and interrupts the flow of electric current.

Ground fault circuit interrupters gfcis or gfis are safety devices built into outlets that protect against electrical shock. 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. A ground fault circuit interrupter gfci can help prevent electrocution. It works by comparing the amount of current going to and returning from equipment along the circuit conductors.

When a ground fault occurs the gfci quickly in a fraction of a second shuts off the power. 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. 2018 was the 50th anniversary of gfci protection in the national electrical code nec. Injury may still occur in some cases for example if a human falls after receiving a shock or if the person touches both conductors at the same time which an rcd won t.

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. At first it was only required for swimming pools and then expanded to outdoor and bathroom receptacle outlets. Gfcis are generally installed where electrical circuits may accidentally come into contact with water.
