Abstract
Apparatus for detecting an overheating condition at an electrical power device and automatically breaking the circuit when the temperature exceeds a setpoint value. In various configurations the device is a receptacle adapted to be used in a wall mounted box or a receptacle unit that is plugged into an existing receptacle and supported in place by the existing receptacle. A temperature switch is wired parallel to a normally open test switch on a ground fault circuit interrupter or other circuit interrupting device. The temperature switch is responsive to the temperature local to the receptacle, such as is caused by poor connections to or in the receptacle. The temperature setpoint is less than the melting temperature of the insulation of the electrical wiring. Upon actuation of the temperature switch, the circuit interrupting device is latched in a tripped position until the device is reset for reuse.
