Apparatus for mounting and supplying power to a luminaire

摘要

A device for mounting and supplying electrical power to a luminaire. The device includes three connectors mounted in a housing. The connectors on the device 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 device to a building structure is adjustable to compensate for fixture balance and the weight of the cables connected to the device. When the luminaire is releasably attached to the device, one of the connectors on the device engages a mating connector on the luminaire for energizing the lighting circuit. The luminaire can be detached from the device without interrupting power to other luminaires in the same circuit.
