Abstract: A multi-part electrical/electronics enclosure that may be used for in-wall installation of intercom, home audio, lighting, HVAC or other automation controls and similar system components. The enclosure includes two major components including a back box, serving to enclose low voltage electronics, and a power pocket portion, fitting into at least one wall of the back box. The power pocket serves as an enclosure for high voltage alternating current electrical wire terminations, equipment connections, power supplies and the like. A trade separator fits between the back box and power pocket to completely enclose and isolate high voltage electrics from low voltage electronics. This solution provides maximize use of available space especially in retrofit applications. It also provides for servicing of electronics (disposed in back box) without accessing or servicing high voltage electrics in the power pocket.
