An improved relocatable wiring system for supplying lighting and power to a floor area in a building is disclosed. A plurality of lighting fixtures installed in a ceiling structure for lighting the floor area are connected in one or more branch circuits. Each branch circuit is defined by a plurality of plural conductor branch circuit cables which distribute power to the fixtures. Connectors are permanently attached to the opposite ends of each branch circuit cable. A connector at one end of a cable is joined to a connector on the next cable in the branch circuit by a circuit connector module having two receptacles keyed to receive and interconnect the two connectors. The circuit connector module also has a connector which mates with a receptacle permanently attached to a lighting fixture, which connector is in turn connected to a lighting circuit in the fixture. A modified circuit connector module has an additional receptacle which is connected through a circuit cable to a wall switch for switching power to one or more fixtures in the branch circuit. Relocatable branch circuits also supply power to the building floor area.
