Ground-fault circuit interrupter (GFCI) The term 'Ground-fault circuit interrupter (GFCI)' as it applies to the area of reclamation can be defined as ' An electrical device designed to protect people (not equipment) from electrical shock. The GFCI is a very sensitive device that can detect ground leakage currents as low as 5 milliamperes. The GFCI can be provided as part of a receptacle or as part of a circuit breaker. When the GFCI detects a ground leakage current, it either deenergizes the receptacle or trips the circuit breaker. Whether the GRCI is part of a receptacle or part of a circuit breaker, it will have a TEST button. Pressing the TEST button will operate the GFCI device and deenergize the circuit. The receptacle will have a RESET button and the circuit breaker is manually reset by hand'.
