Abstract:
A wiring device including a fault detection circuit, an actuating device, a first switching device, a second switching device, and a third switching device. The fault detection circuit is configured to detect one or more fault conditions and generate a trigger signal. The first switching device is activated to turn on when said trigger signal is received from said fault detection circuit. The second switching device includes a first pin, a second pin, and a third pin, said second switching device is electrically connected to a first conductive winding of the actuating device and said first switching device. The third switching device includes a first pin, a second pin, and a third pin, said third switching device is electrically connected to a second conductive winding of the actuating device and said first switching device.
