Ground-Fault Circuit-Interrupters (GFCI) A ground fault occurs when the electrical current does not complete its circuit and unintentionally flows to the ground. Ground faults can cause fires and are dangerous when they flow through a person to the ground. The GFCI, as it is commonly called, is simply a fast-acting...
Ground-Fault Circuit-Interrupters (GFCI) The most common electric shock hazard, ground faults, can cause severe electrical shock or electrocution. In normal conditions, electricity runs in a closed circuit; electricity flows out on the “hot” wire and returns on the “neutral” wire, completing the circuit. A ground fault occurs when the electrical...
