Title: Plug-in lighting system

Abstract: A device for mounting and supplying electrical power to a luminaire. The device includes two connectors mounted on opposite sides of a housing which is mounted on the luminaire. The connectors on the device are wired to electrically interconnect two cables and a lighting circuit in the luminaire. Power is applied from one cable through the device to the luminaire and to the other cable which supplies power to another luminaire. A bracket on the top of the housing for mounting the luminaire in a building structure is adjustable in a direction extending linearly between the connectors to compensate for fixture balance and the weight of the cables connected to the device.
