Answer
The GFCI interrupts the current
Step-by-step explanation
A ground Fault Circuit Interrupter (GFCI) is a type of circuit breaker responsible for shutting off electric power where there is an imbalance sensed between the current outgoing and that incoming. An imbalance can be sensed as small as 4 milliamps, and the circuit breaker reacts instantly to cut the flow of current.
