Patent ID: 8550672

Claim:
Apparatus for providing power to pole-mounted HID lighting fixtures comprising: a support comprising a vertical member and two vertically spaced parallel cross-arms fixed thereto, said support adapted to be mounted on a pole at a position remote from said fixtures; a weather tight enclosure fixedly mounted on said support for housing electrical components; a first electrical plug connector mounted on the exterior of the enclosure; an electronic ballast unit; a pair of standoff brackets fixedly secured to the ballast unit with a vertical spacing between said brackets equal to the vertical spacing between said cross-arms such that the ballast unit may be mounted to the cross-arms by way of said standoff brackets, said standoff brackets having elongate screw holes formed in laterally opposite portions thereof; the horizontal distance between the elongate screw holes being greater than the width of the ballast unit whereby the ballast unit may be secured to said cross-arms by access to screws in said screw holes; said elongate slots providing limited sliding movement of said ballast unit relative to said support and said cross-arms during installation; and a second electrical plug connector mounted on said ballast unit and being complemental and joinable to the first electrical plug connector; said plug connectors being aligned when the ballast unit is mounted on the support by way of the cross-arms and standoff brackets, such that the limited sliding motion of said ballast unit relative to said support joins said plug connectors to make an electrical connection.
