Abstract: An electronic cabinet is described which contains both control circuits containing heat producing components and a plurality of circuit breakers. The control circuits and the circuit breakers are located inside the cabinet with heat dissipating fins being located outside of the cabinet in a heat dissipating chimney. Air moves through the chimney by convection and cooperates with the heat dissipating fins to dissipate most of the heat generated by the heat-generating components of the control circuits. Openings are provided in the cabinet to permit cooling air to pass through the interior of the cabinet and over the control circuit components. These two paths of cooling air cooperate to reduce the temperature in the cabinet to a sufficient level to permit the circuit breakers to be located in the same chamber as the control circuits.

Abstract: A wall box dimming system assembly controls the intensity level of a plurality of groups of lights in accordance with a plurality of preset scenes. A face plate assembly which is coupled to the housing of the wall box dimming system includes a face plate. The face plate is formed of a generally opaque material and has front and rear surfaces. A recess is formed in the face plate, the recess extending from the rear surface of the face plate to near the front surface thereof such that a relatively thin region of material remains adjacent the front surface. A lamp is located adjacent the rear surface of the face plate in the area of the recess. The thickness and opacity of the thin region of material and the intersity of light generated by the lamp are such that light can be seen from a position in front of the front surface of the face plate when the lamp is on.
