Problems solved by technology

In addition, the use of bolts complicates the field of busway construction since the busway housing is usually at ground potential and the bolts themselves will not touch any part of the conductors.

Embodiment Construction

[0023] Embodiments of the present invention relate to systems and methods for securing power busway assemblies that reduce the need to use fasteners, employ fewer components, yet provide predictable consistent strength and high short circuit power.

[0024] The prior art busway housing is in figure 1 Expressed in 10 overall. The housing unit 10 comprises a side panel or side part 11 positioned opposite a complementary side panel or side part part 12 . The side panels 11, 12 are each shown as having a U-shaped configuration, may include openings (not shown), and comprise a non-ferrous metal, such as an aluminum alloy, which greatly increases the ductile strength of the aluminum without substantially compromising good electrical and thermal properties . The aluminum side panels 11, 12 forming the busway housing 10 form a complete 360 ​​degree high grade grounding path for ground faults and serve as a continuous bond between busway sections, fittings and busbar plugs (not shown...

Abstract

The invention relates to a system and method for securing a busway housing to busway power conductors. The power busway assembly includes a pair of opposing non-ferrous metal apertured side plates. The side plates have a U-shaped configuration and include a pair of top and bottom flanges that are joined by a flat piece. The power busway assembly further includes a means on one end of each of the flanges for interlocking the side plates together. The interlocking means intern has an angulated projection or an angulated slot. First rails extending from one of the pairs of flanges are also included that provide hanger support connection means. In addition, second rails extending from another one of the pairs of flanges are included that provide ground stab connection means. The power busway assembly further includes at least one brace that is interconnected with the flanges. The brace is dimensioned and configured to bias the interlocking means together.

Description

technical field [0001] The subject matter described herein relates generally to power busways, and more particularly to securing busway housings to busway power conductors. Background technique [0002] Power busways used in polyphase electrical energy distribution systems typically comprise long, rectangular rods of aluminum material. Each individual bar is electrically insulated so as to maintain electrical separation between the individual phases and between the phase conductors and the neutral conductor. According to electrical codes, grounding conductors must be relevant in busway power distribution systems. [0003] US Patent No. 4,804,804 entitled "Thermally Efficient Power Busway Housing" describes a two-piece extruded aluminum alloy housing shaped to provide support and ground conductors for said power busway conductors. The two-piece housing is joined together along its top and bottom surfaces by snap-fit ​​connections. The housing is connected to the busway pow...
