    摘要: A self test (ST) ground fault circuit interrupter (GFCI) provides improved end of life (EOL) detection by rejecting false EOL information. A processing device receives fault detection signals indicating when faults are detected, and input signals indicating when contacts used to interrupt power to a load are closed. The processing device rejects the fault detection signals when they fail to meet a selected condition and the contacts are closed, and declares end of life (EOL) when the selected condition is met. The fault detection signals can correspond to pulses at an output of a gated device between the processing device and a GFCI chip, and the selected condition can be a selected integer number of pulses.

    摘要: An improved GFCI device prevents miswiring. Load conductors are electrically isolated from receptacle conductors. Normally closed contacts are held open by a miswire prevention mechanism, such that if power is connected to the load contacts, power cannot be delivered to the GFCI device, the receptacle conductors or the line conductors. Once power is properly connected to the line conductors, a proper wiring detection circuit activates the miswire prevention mechanism to release the normally closed contacts, thereby electrically connecting the receptacle conductors and the load conductors. After proper installation, the receptacle conductors are preferably permanently connected to the load conductors. The device is preferably shipped in the reset state.
