Abstract
A circuit is disclosed for disconnecting electrical power upon the detection of an elevated temperature comprising an electrical plug and an electrical receptacle interconnected by a power cable. An interruption circuit having a disconnect switch is interposed in the power cable. A plug heat sensitive device and a receptacle heat sensitive device monitor the temperature of the electrical plug and the electrical receptacle. An elevated temperature detection circuit opens the disconnect switch upon the detection of an elevated temperature in one of the electrical plug and the electrical receptacle to prevent an overheated condition.
