An electrical enclosure includes a first wall having an exhaust opening, a second wall, and a third wall. The electrical enclosure also includes at least one circuit breaker compartment, a line compartment arranged between the third wall and the at least one circuit breaker compartment, and an exhaust duct extending through the electrical enclosure between the first wall and the second wall. The exhaust duct is fluidically connected to the exhaust opening and each of the at least one circuit breaker compartments. At least one passage extends between the line compartment and the at least one circuit breaker compartment through the exhaust duct. The at least one passage is substantially fluidically isolated from the exhaust duct.

A shutter system for a switchgear compartment includes a moveable shutter translatable between a closed position and an open position. Also included is a pusher operatively coupled to a first side of the moveable shutter and configured to impart a force on the moveable shutter in response to an insertion of an electrical device within the switchgear compartment. Further included is a cam member having a cam shaft operatively coupled to the moveable shutter, the cam shaft having a cam track. Yet further included is a bell crank configured to guide along the cam track and translate the moveable shutter between the closed position and the open position.

An adjustable busway joint for coupling two longitudinally aligned busway sections is disclosed. The adjustable joint has a first plurality of electrically conductive splice plates defining a splice plate adjustment slot, and a second plurality of electrically conductive splice plates defining an aperture, wherein each splice plate of the second plurality of splice plates is disposed to overlap a portion of a corresponding splice plate of the first plurality of splice plates to form an electrical joint, and wherein the aperture is sized and disposed to overlap at least a portion of the first splice plate adjustment slot. The joint additionally has a first clamping member disposed through the splice plate adjustment slot and the aperture such that the first and said second pluralities of splice plates are operably movable with respect each other between a first compressed position and a second extended position.

Adjustable electrical busway joint

An adjustable length busway joint for coupling a first and a second busway section, the first and second busway sections being longitudinally offset, is disclosed. The busway joint includes a first plurality of splice plates and a second plurality of splice plates disposed to overlap to form an electrical joint. The first and said second pluralities of splice plates are arranged for a longitudinal movement with respect each other between a first compressed position and a second extended position. The busway joint further includes a third plurality of splice plates. Each splice plate of the second plurality of splice plates overlaps a portion of a corresponding splice plate of the third plurality of splice plates to form an electrical joint. The third and second pluralities of splice plates are arranged for a longitudinal movement with respect each other between a third compressed position and a fourth extended position.
