Abstract
An over heating detection circuit and an interrupter circuit are disclosed for interrupting electrical power from a power source receptacle to a load upon the detection of an over heating condition of an electrical plug. A heat sensitive device monitors the temperature of the electrical plug. The over heating detection circuit is connected to the heat sensitive device for detecting an over heated condition in the electrical plug. The interruption circuit includes a disconnect switch connected to the over heating detection circuit for disconnecting electrical power upon the detection of the over heated condition in the electrical plug.
