Abstract
Systems and methods that provide improved detection of series fault conditions are described. The systems provide an increased range of response possibilities upon detection of such conditions. Solid-state temperature sensors are utilized and may be connected to a printed circuit board integrated with supply wire terminals, thus providing electronic circuitry controlling the response to over-temperature events while simultaneously keeping the temperature sensors in close proximity with the location of potential over-heating events. Electronic sensors in accordance with implementations of the present invention detect overheating conditions at temperatures more quickly because of the close proximity of the sensors to locations of potential overheating, thereby improving the safety of electrical wiring devices and fixtures. Additionally, the threshold temperature for response can more easily be selected or controlled to be at a variety of temperatures to improve safety.
