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.
