ATO ground fault circuit interrupter (GFCI) outlet is built to meet every need in commercial, industrial, household, institutional settings. This GFI socket has safe lock function, the reset button will not engage if protection has been compromised. The LED indicator light on our electrical receptacle gives a quick notification of a tripped or "end of life" condition.

Tips: How does a GFCI outlet work?
A GFCI receptacle must be properly installed with one set of terminals connected directly to the live, neutral, and ground terminals of the power supply. When the circuit is active, this connection powers a set of circuits within the socket and indicates functionality via a green LED. Without power, the circuit will not work. So on these sockets, you cannot press the test or reset button until power is connected.
Inside the socket, two small induction coils measure the current flowing through the live and neutral wires very accurately. These numbers should be equal in all cases. All current supplied through the hot wire should be returned through the neutral wire, regardless of whether the load is connected to this socket or downstream.
If the current supplied by the hot wire exceeds the current in the neutral wire by more than 5mA, it immediately breaks the circuit with a small solenoid. If this overcurrent is detected, it means that the current somehow leaves the circuit and returns through another path to ground. If water is present, the return path may pass through any nearby metal.
