The input circuit has a first pin, a second pin, a third pin, and a fourth pin. The first pin is connected to the live-wire output terminal of an external power source via a main switch. The second pin is connected to the live-wire output terminal. The third pin is connected to the neutral-wire output terminal of the external power source via the emergency test switch. The fourth pin is connected to the neutral-wire output terminal. The processing circuit is connected to the input circuit. The emergency circuit is connected to the processing circuit. The load is connected to the emergency circuit.",
