The present invention provides for a calculation and pre-setting of even spring compression among the spring hangers of a vertical busway riser, by use of rigid elements in the hanger with the ability to retain the spring compression during construction of the busway, and the ability to release and load the spring hangers only after construction of the riser is completed.

Busway vertical spring hanger

A busway joint pack includes a pair of opposing phase connector plates, a first insulating sheet, a second insulating sheet, a first side panel, and a second side panel. The busway joint pack passively transfers thermal energy generated in its core to an exterior housing such that the thermal energy is dissipated or transferred to the surrounding environment, which reduces the internal temperature of the joint pack. The first and the second insulating sheets are positioned and selected with a particular thermal resistance and dimensions such that a portion of the thermal energy generated in the core of the busway joint pack is transferred from the pair of opposing phase connector plates to the external housing.

Thermally efficient busway joint pack

A sprinkler and drip resistant tap-off base for an electrical busway distribution system. The tap-off base includes an overmolded perimeter seal providing a liquid resistant seal between the busway housing and the tap-off base and between the tap-off base and a tap-off unit installed on the tap-off base.

Sprinkler resistant tap-off base assembly

A field convertible tap-off base for an electrical busway distribution fitting. The field convertible tap-off base includes an AC phase termination side and a field configurable side having first and second configurable electrical terminals. The AC phase termination side provides terminals for connecting three AC phase conductors of a busway electrical distribution system to any one of a number of load bases configured for electrical components such as circuit breakers, switches, fuses, lugs or other special functions. The first and second configurable terminals permit two additional busway electrical conductors to be used for neutral, high current capacity neutral, secondary ground, DC current or other special functions which might be defined in the busway electrical distribution system.

An elbow for changing the run direction of a pre-bussed rigid conduit electrical distribution system. The elbow has a number of individually insulated electrical conductors each of which is formed to a predetermined angle. The conductors are enclosed within a hollow housing which is formed to the same predetermined angle such that it will enclose the electrical conductors. A uniform and continuous support is provided for that portion of each electrical conductor which is enclosed within the housing.

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

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.

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

A connector for electrically connecting a plurality of electrical conductors of a first busway section to a plurality of electrical conductors of a second busway section. The electrical connection is accomplished by a plurality of pairs of electrical joint connectors, each pair having an independently operable rotational clamping mechanism for clamping that pair of joint connectors tightly to corresponding electrical conductors of the first and second busway sections. An activating cap is used to manually rotate the clamping mechanism between a first and second position. In the first position the pairs of joint connectors are clamped tightly to the busway conductors. In the second position the pairs of joint connectors are loosened permitting an easy insertion or removal of the busway conductors. The pairs of joint connectors of opposite polarity are separated from each other by a phase insulator. Phase insulators also separate the electrical phases from a protective enclosure surrounding the busway. The joint connectors, rotational clamping mechanism, and phase insulator are held in place by an electrically insulated frame comprised of two halves. The frame is held together by four assembly rods which pass through the two halves of the frame. A cover plate for closing a joint access opening in the busway protective enclosure locks the rotational clamping mechanism in its first position preventing it from rotating to its second position.
