This year, in the U.S. alone, approximately 800 people will be killed by faulty electrical appliances and power tools; hundreds more will be severely injured. Worn insulation, wire damage, and moisture- induced short-circuits can make these devices as “hot” as the power lines to which they are attached. The most...
Although most portable electric tools have an equipment- grounding conductor and many are double insulated, these methods are not fool proof. A grounding wire could break, or a cord could become defective. Using a GFCI overcomes these insulation problems. A ground fault occurs when the electrical current does not complete...
According to the U.S. Department of Labor’s Bureau of Labor Statistics, in 2016, there were 1,480 workplace injuries from electrical shock and 1,100 injuries caused by contact with electric current that resulted in burns. The most common electric shock hazard, ground faults, can cause severe electrical shock or electrocution. In...
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 circuit breaker that...

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...
