Abstract: A modular, branch circuit electrical power distribution system and components therefore, of the flexible wiring type. Lighting fixtures and devices are wired to connectors which employ contact assemblies comprising an integral combination of a male contact, a female contact, interconnecting bussbar and wire-securing means. This entire integral assembly is formed from a single piece of suitably cut and bent sheet metal stock. The integral male contact, female contact, bussbar, and wire-securing means contact assembly. This contact assembly permits power to be received from one cable set, transmitted to another cable set and tapped off to feed a fixture, receptacle, or other device. Cable sets have male connectors at one end and female connectors at the other end; other system components employ similarly corresponding sets of male and female contacts. Switches and receptacles are connected to couplers which may be fed by cable sets.
