Abstract
A wiring device includes a housing that encloses a line voltage port and/or a low voltage port for providing power to at least one removable load. The housing has an intake opening and an exhaust opening for drawing cooling air into the housing and for exhausting heated air. A fan is disposed within the housing and operates to move the air through the housing. A thermal load such as a heat sink or a transformer is positioned within the housing and receives cooling air to reduce the temperature of the load. The fan is energized when a sensed temperature in the housing exceeds a first predetermined threshold. Power to the line and/or low voltage port is reduced or shut off if the sensed temperature in the housing exceeds a predetermined value that is greater than the first predetermined threshold.
