ABSTRACT:
An improved electrical distribution system with two, four wire, multiwire branch circuits providing two sets of single phase office power circuits in exactly two types of duplex outlets. In each duplex outlet, receptacles are split to offer power from different phases. Each type of duplex has its own neutral and ground wires. These two duplexes control neutral balance and eliminate the previous need for oversized neutrals. Therefore, exactly two types of duplexes may be permanently prewired to a modular symmetrical channel providing user access to all four available circuits. The two multiwire branch circuits may be shielded to isolate clean computer power in one of the two duplex types.
