Abstract: A ground fault circuit interrupter device includes a switch module having a reset switch, a control switch mechanically linked to the reset switch, a ground fault detection module, a self-testing module and a tripping module. The switch module controls the electrical connection between the input and output ends of the device. The ground fault detection module detects a leakage current signal at the output end. The self-testing module is coupled to the ground fault detection module and periodically generates a self-test pulse signal which simulates the leakage current signal. The tripping module is electrically coupled to the ground fault detection module and mechanically coupled to the switch module and the control switch, to control the movement of the switch module and the control switch. The control switch, which opens and closes at the same time as the reset switch, controls the power supply to the self-testing module.

Abstract: A leakage current detection device connected between a power source and a load, which includes a self-testing or leakage current detection selection trigger unit, for selecting a leakage current detection mode or a self-testing mode; a self-testing unit, for periodically generating a simulated leakage current signal in the self-testing mode; and a leakage current detection unit, for detecting a leakage current signal in the leakage current detection mode and detecting the simulated leakage current signal in the self-testing mode. The selection trigger unit further causes the power source to be disconnected from the load when a leakage current signal is detected, and sends a self-testing result to the self-testing unit depending on whether the leakage current detection unit detects the simulated leakage current signal. The self-testing unit displays an indication of the self-testing result.

Abstract: A power cord having a circuit interrupter such as a leakage current detection interrupter (LCDI) or arc fault circuit interrupter (AFCI), with a detection signal conductor wire in addition to the current carrying wires between the source and the load, and a temperature controlled switch coupled to the detection signal conductor wire on the load side. The temperature controlled switch is affixed to a device under measurement which is associated with the load, and changes its open or closed state when the device overheats. This in turn changes the state of the current flowing in the detection signal conductor wire. In response thereto, the circuit interrupter, which is coupled to the detection signal conductor wire on the source end, interrupts the power supply to the load.
