The electrical current may then take an alternative path to the ground through the user, resulting in serious injuries or death. The ground-fault circuit interrupter, or GFCI, is a fast-acting circuit breaker designed to shut off electric power in the event of a ground-fault within as little as 1/40 of a second. It works by comparing the amount of current going to and returning from equipment along the circuit conductors.
A ground fault circuit interrupter is not the same thing as a circuit breaker. A GFCI is intended to prevent stray currents from causing shock hazzards. As the answer states, it measures the current difference between the hot wire and the nuetral. I the current difference exceed 0.2 amps, the GFCI opens the circuit.
