An device for changing the run direction of a pre-bussed rigid conduit electrical distribution system. The device has a number of electrical conductor assemblies which are substantially enclosed within a hollow housing. The housing has three legs which are integrally joined at a common point. Each leg has an associated end from which an equal length of each electrical conductor assembly extends. A uniform and continuous support is provided for that portion of each electrical conductor assembly which is enclosed within the housing.

Device for changing the run direction of a pre-bussed rigid conduit

An end feed connector for connecting a plurality of feed lines to a pre-bussed rigid conduit which has feed line connectors that fit in slots in an insulating housing. Within the housing, the slots communicate with conductive sleeves that are disposed in the pattern of the pre-bussed rigid conduit with which the end feed connector is intended to mate. Bus bars within the housing connect the feed line connectors to the sleeves.

End feed connector for pre-bussed rigid conduit

A sectionalized electrical distribution feeder system for carrying electrical power from a source point to a use point or a distribution point. Each section of the distribution system includes a substantially cylindrical enclosure capable of being easily cut with a hand saw. The enclosure also provides support and protection from physical damage to a plurality of electrical conductors which are disposed within the enclosure. The conductors are held firmly in place by a number of electrically insulating supports which snugly fit inside the enclosure. Each conductor can be easily cut with a metal cutting hand saw, and is enclosed in an electrically insulating sheath which can be removed from a newly cut end to provide a contact surface. A joint connecting member is provided for electrically connecting the conductors of adjacent sections of the electrical distribution feeder system. A joint cover connects the two adjacent enclosures together and provides additional protection for the joint connecting member.

Pre-bussed rigid conduit

This present invention provides an inexpensive and easily installed supplementary joint cover system for preventing dripping or splashing water from entering the joint between two adjacent sections of electrical busway. Each busway section includes a housing having an enclosure for surrounding and protecting a plurality of electrical conductors. A pair of housing sides are attached to and spaced apart by the enclosure such that two generally U-shaped troughs are formed. The joint cover system includes four dam assemblies, four sealing strips, two cover plates, two inspection hole plugs, and two connecting channels. Each of the two adjacent busway sections requires two dam assemblies to seal the busway housing at the joint. The dam assemblies form a water resistant block in the troughs formed by the busway housing. The sealing strips are placed across the dam assemblies and provide a seal for the cover plates. The connecting channels have a cross-sectional shape which cooperates with the busway housing sides such that the connecting channel nests with the busway housing side. A water resistant gasket is attached to a nesting side of the connecting channel. As the connecting channel is tightened against the two adjoining busway housing sides it compresses the water resistant gasket sealing the two adjoining busway housing sides and the two cover plates against the ingress of water.
