Abstract: A GFCI device with circuit condition detection function includes a leakage current detection circuit, a disconnect mechanism, a reset mechanism, a circuit condition detection and control circuit, and a selection switch. The disconnect mechanism includes a first SCR controlled by the leakage current detection circuit. The circuit condition detection and control circuit includes a first control circuit and a second control circuit. When the first control circuit is connected to an anode of the first SCR by the selection switch, it provides an intermittent simulated leakage current to the leakage current detection circuit, and the leakage current detection circuit provides a trigger signal for a control gate of the first SCR, so that the first control circuit generates an intermittent simulated leakage current. When the leakage current detection circuit is not operational to generate the trigger signal, the first control circuit generates a control signal to disable the GFCI device.

Abstract: A ground-fault circuit interrupter (GFCI) device, including a relay for control a switch to be in an open position or a closed position, the relay including a first coil and a second coil, wherein when both the first coil and the second coil are non-conductive, the switch is caused to be in the open position. The GFCI also includes a relay start circuit connected to the first coil for causing the first coil to be conductive or non-conductive, wherein when the first coil is conductive, the first coil causes the switch to be in the closed position, but after the first coil is conductive, the coil start circuit becomes non-conductive. The GFCI further includes a relay sustain circuit connected to the second coil for causing the second coil to be conductive or non-conductive. In addition, the GFCI includes a ground fault detect circuit for causing both the relay start circuit and the relay sustain circuit to become non-conductive when a fault signal is detected, causing both the first coil and the second coil to be non-conductive, thereby causing the switch to be in the open position.
