Power pole wiring assembly

Claim 1

A multi-purpose power hole wiring assembly for use with a power hole of the type having an elongated housing dimensioned to extend from a location above a false ceiling down to a surface below the ceiling, an elongated barrier dividing the interior volume of the housing into power and communication chambers for receiving power wires and communication wires, respectively, extending between outlet locations along the pole and the top of the pole, the housing top further comprising means having mounting openins protruding inwardly from opposite sides thereof, the wiring assembly comprising the combination of a flat, rectangular, stiff, metal mounting plate, each side of which is significantly longer than any cross-sectional dimension of the top of the housing; first and second mounting holes through said plate alignable with said mounting openings for receiving threaded fasteners to attach said plate to the top of said pole across the open end thereof above said ceiling; a first wire hole through said plate for passing wires therethrough to and from said communication chamber, said first wire hole being aligned with said communication chamber when said mounting holes are aligned with said mounting openings; a second wire hole through said plate for passing wires therethrough to and from said power chamber, said second wire hole being aligned with said power chamber when said mounting holes are aligned with said mounting openings; a plurality of sets of threaded holes through said plate, each set being positioned to be uniquely alignable with standard mounting holes in one extension ring selected from a plurality of extension rings of different sizes to permit mounting said one extension ring on said plate to thereby form a junction box on said plate; and an extension barrier having a wall portion and a flange portion, said flange portion having openings alignable with said mounting openings for attachment of said barrier with the same threaded fasteners holding said plate, said wall portion being substantially aligned with the barrier in said pole.
