What is a GFCI outlet?
- Jan 04, 2019 -

A ground fault interrupter is a protection device specifically designed to open the circuit whenever there is an imbalance between the input and output currents. GFCI sockets prevent overheating of wires and sockets and possible fires, greatly reducing the risk of shock and fatal burns. It also detects ground faults and interrupts current, but it is not used to replace fuses because it does not provide short-circuit and overload protection.
