A busway system is provided. The busway system includes a first electrical busway section, a second electrical busway section, and a busway joint. The first and second electrical busway sections are disposed longitudinally offset from each other. The busway joint couples the first and second busway sections. The busway joint includes a first assembly coupled to the first busway section, a second assembly coupled to the second busway section, a plurality of conductors coupled to the first and second assemblies, a first movable brace coupled to the conductors, and a first brace locator coupled to the movable brace. The first and second assemblies move relative to each other between a collapsed position and an extended position. The first movable brace moves longitudinally along a length of the conductors. The first brace locator locates the first movable brace at a first position when the first assembly is in the extended position.

Electrical busway joint with self-adjusting braces

A busway system is provided. The busway system includes a first electrical busway section, a second electrical busway section, and a busway joint. The first and second electrical busway sections are disposed longitudinally offset from each other. The busway joint couples the first and second busway sections. The busway joint includes a plurality of busbars, a plurality of splice plates coupled to the busbars, and a vise brace surrounding the busbars and the splice plates. The splice plates and the busbars electrically couple the first and second electrical busway sections. The vise brace includes a clamp screw to selectively provide a compressive force to the busbars and the splice plates.

Electrical busway joint with external vise braces

A busway system is provided. The busway system includes a first electrical busway section and a busway joint. The busway joint includes a plurality of conductors spaced apart in parallel and a first assembly. The conductors and the first assembly are coupled to the first busway section. The first assembly includes a plurality of insulation laminations spaced apart to define a plurality of gaps, a plurality of insulating spacers positioned within the gaps adjacent the conductors, and a plurality of bracing fasteners extending through the insulation laminations and the insulating spacers. Each gap receives at least one conductor. A width of the gap is substantially filled by the conductors and the insulating spacers. The bracing fasteners secure the conductors within the first assembly.

Electrical busway joint with laminated bracing system

A busway system is provided. The system includes a first electrical busway section, a second electrical busway section longitudinally offset from the first electrical busway section, and a busway joint coupling the first and second electrical busway sections. The busway joint includes a plurality of splice plates. Each splice plate includes a longitudinal rib configured to transfer a compressive force through the busway joint.

Busway joint coupling having a splice plate with a longitudinal rib

A busway system is provided. The busway system includes a first electrical busway section, a second electrical busway section, and a busway joint. The first and second electrical busway sections are disposed longitudinally offset from each other. The busway joint couples the first and second busway sections. The busway joint includes a plurality of busbars, a plurality of splice plates electrically coupled to the busbars, a first assembly coupled to the first electrical busway section, a second assembly coupled to the second electrical busway section, and an adjustment assembly coupled to the first and second assemblies. The splice plates and the busbars electrically couple the first and second electrical busway sections together. The adjustment assembly selectively moves the first and the second assemblies between a contracted position and an expanded position relative to each other.

Busway joint coupling having an adjustable assembly for joining two busway sections

An electrical switching apparatus for housing a pair of opposing circuit breakers includes a panelboard having a first longitudinal axis and configured to support the pair of opposing circuit breakers to define a gap therebetween, the gap having a second longitudinal axis extending generally parallel to the first longitudinal axis. An insulative barrier is arranged to define a plenum region having a third longitudinal axis, and is operatively disposed in the gap, wherein the third longitudinal axis extends generally parallel to said second longitudinal axis.

Panelboard insulative plenum

An electrical switching apparatus for housing a pair of opposing circuit breakers each circuit breaker of the pair of opposing circuit breakers having an opposing end face including an exhaust vent disposed thereon is disclosed. The electrical switching apparatus includes a panelboard to operatively support the pair of opposing circuit breakers to define a gap therebetween, and an insulative barrier to be operatively disposed in the gap. The insulative barrier includes a first cantilever wall member arrangeable to define a first plenum region having a first cross sectional area, and a second plenum region having a second cross sectional area. The insulative barrier is operative to deflect in a first direction to thereby increase one of the first and second cross sectional areas in response to a venting of ionized gases from one circuit breaker of the pair of circuit breakers.
