Answer: Protect people from severe and sometimes fatal electrocution by monitoring for electrical leakage to ground.
Explanation:
The main purpose of a Ground Fault Circuit Interrupter (GFCI) is to ensure that when a person gets electrocuted, the flow of electricity is cut off quickly so that no serious injuries or death occurs.
It works by monitoring the electrical leakage to the ground by checking to see if the current going to and coming from the equipment differ by a certain amount and if it does, the GFCI will interrupt the circuit.
