More Information
Summary:A receptacle having at least one thermally sensitive electrically conductiv e element made of, for example, a thermally conductive plastic which either increases or decreases its conductivity when subjected to an increase in temperature. The thermally sensitive element is positioned within the housing of the receptacle such th at it makes contact with a blade of an inserted plug or a blade receiving contact in the receptacle. By contacting at least one blade of a plug, or the blade receiving contact in t he receptacle, the thermally sensitive element is positioned to detect a temperature rise. A circuit interrupting device located within the receptacle and coupled to the thermal ly sensitive element is configured to cause electrical discontinuity between the line and load of the receptacle upon the detection of a high heat condition by the thermally conductive element.
