Ground faults occur when a current circuit comes into contact with grounded conducting material.
When a GFCI detects a leakage in electrical currents as low as 4 to 6 milliamperes, it will immediately cut the circuit. However, any power higher than 5 milliamperes can result in injuries ranging from loss of muscle control to death. Install GFCIs at the source of power, or near it. It is important to test GFCIs monthly or after electrical storms. Plug in a nightlight or similar device and turn it on.
