Abstract
Abstract A two-piece extruded aluminum alloy housing is shaped to provide support and ground conduction facility to power busway conductors contained therein. The two-piece housing is attached together with snap-fit connectors along its top and bottom surfaces. The housing is attached to the busway power conductors by means of insulated bolts. The bolts may be hollow so that air can flow through the bolts to aid in cooling the conductors within the housing by convection.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
A power bus support housing comprising: a pair of opposing non-ferrous metal apertured side plates, each of said plates having a U-shaped configuration consisting of a pair of top and bottom flanges joined by a plate; means on one end of each of said flanges for interlocking said side plates together, said interlocking means comprising an angulated projection or an angulated slot; first rails on an opposite end of one of said flanges, said first rails providing hanger support connection means; and second rails on an opposite end of another of said flanges, said second rails providing ground stab connection means.
Claim 2
Dependent Claim
101 words
A power bus support housing comprising: a pair of opposing non-ferrous metal apertured side plates, each of said plates having a U-shaped configuration consisting of a pair of top and bottom flanges joined by a plate; means on one end of each of said flanges for interlocking said side plates together, said interlocking means comprising an angulated projection or an angulated slot; first rails on an opposite end of one of said flanges, said first rails providing hanger support connection means; and second rails on an opposite end of another of said flanges, said second rails providing ground stab connection means.
Claim 3
Dependent Claim
12 words
The support housing of claim 1 wherein said side plates are extruded.
Claim 4
Dependent Claim
20 words
The support housing of claim 1 wherein said non-ferrous metal is selected from the group consisting of aluminum and copper.
Claim 5
Dependent Claim
82 words
A power busway system comprising: a pair of apertured non-ferrous metal side plates arranged on either side of a plurality of apertured bus conductors; hollow bolt attachment means extending through said side plates and said bus conductors and holding said side plates and bus conductors in thermal proximity; insulative means on each of said bus conductors to electrically isolate said bus conductors from each other and from said side plates; and an insulative sleeve intermediate said attachment means and said bus conductors.
Claim 6
Dependent Claim
82 words
A power busway system comprising: a pair of apertured non-ferrous metal side plates arranged on either side of a plurality of apertured bus conductors; hollow bolt attachment means extending through said side plates and said bus conductors and holding said side plates and bus conductors in thermal proximity; insulative means on each of said bus conductors to electrically isolate said bus conductors from each other and from said side plates; and an insulative sleeve intermediate said attachment means and said bus conductors.
