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...
Ground Fault Circuit Interrupters (GFCIs) Although most portable electric tools have an equipment grounding conductor and many are double insulated, these methods are not foolproof. A grounding wire could break or a cord could become defective. Using a GFCI overcomes these insulation problems. Not the proper use of GFCIs Where...
