The power bridge rollout service system includes a roller assembly, an enclosure assembly, and a dolly assembly. The roller assembly is structured to support the power bridge and has a plurality of wheels. The enclosure assembly has a frame assembly structured to support the power bridge and has two wheel tracks. The dolly assembly has a frame assembly, a vertical lifting device, and a plurality of wheels. The vertical lifting device and wheels are coupled to the dolly frame assembly. The vertical lifting device acts upon a work platform such as a skid table assembly. The skid table assembly has a generally flat lifting plate. The skid table assembly may be raised so that the lifting plate is at the same general height as the frame assembly wheel tracks. Thus, the lifting plate is adjacent to the frame assembly wheel tracks so that the roller assembly and power bridge may be rolled from the enclosure assembly onto the skid table assembly. Once the roller assembly and power bridge are on the dolly assembly, the power bridge may be transported away from the enclosure assembly.

A pair of circuit boards, or electrically insulative panel members on which the circuit boards are mounted, have side edges which slide into aligned longitudinally extending slots in a pair of facing, spaced apart cantilevered free sections of a pair of planar legs of a bracket secured to a panel in an electric power equipment enclosure. A terminal portion of one free section diverges outward to form a camming surface against which a complimentary camming surface on a rearward edge of a tab on the associated side edge of the panel member bears to spread the free section apart until the tab passes into the slot and the terminal portion snaps over the tab and engages a latching surface on the forward edge of the tab to latch the panel member to the bracket. The panel member is released by lifting the diverging terminal portion of the one free section to clear the latching surface and sliding the panel member out of the slots.

Power switches are fix mounted in a switchgear cabinet by providing terminal sections on power conductors at the rear face of the switch housing which extend vertically beyond the housing. The power switches slide into cells in the cabinet through a front opening with projections on the sides of the switch engaging slots in mounting panels in the cabinet. The terminal sections of the power conductors are then accessible through the front opening for connection to the buses in the switchgear cabinet. Runbacks secured to the lower power conductors on the bottom power switch extend into a rear compartment in the cabinet for the connection to power cables as the power switch is inserted into the front compartment. A unitary arc shield/wire tray slides into the front compartment above the power switches after connection of the terminal sections to the buses and is removable to provide subsequent access to the power connections.

The cross buses extending through side-by-side cabinets in a switchgear assembly are mounted on the metal cabinet frames by supports having a molded body with a bus bar mounting surface laterally spaced from a support mounting surface to form a gap between the bus bar and the metal frame. A planar barrier inserted between the cabinets has a cutout aligned with this gap. The molded support further has a barrier surface which extends across the gap and blocks the cutout. The barrier surfaces of supports mounted on side-by-side cabinets abut and parallel flanges on the molded bodies adjacent the barrier surfaces form grooves in which the planar barrier is clamped.

The interface conductors, stabs and runbacks, which are engaged at first ends by quick disconnects on electrical apparatus in a switchgear assembly, are fabricated from a stacked pair of elongated, flat conductors secured together at the first ends by elongated fasteners which are compressed into countersunk through apertures in the flat conductors to form a joint with no lateral projections. The interface conductors are supported adjacent the disconnects by a first support having a base member with through openings in which the conductors are snugly supported, and rigid projections with planar surfaces extending from the base member toward the quick disconnects alongside the openings and against which the interface conductors are secured adjacent free ends of the projections. A second support spaced rearward of the first support provides additional support for the runbacks. Interphase supports formed by C-channels are provided for the runbacks between the first and second supports.

A hinge assembly for an enclosure for electrical apparatus includes a hinge pin non-rotationally fixed to either the door or the door jamb. A hinge housing is secured to the other of the door and the door jamb and clamps the hinge pin with a compression fit. The housing includes an angle member forming an internal corner and a clamping member having clamping flanges forming at least one, and preferably a pair, of spaced apart, external corners with corner recesses smaller in radius than the hinge pin in which the hinge pin is received and wedged into the internal corner of the angle member. Clamp tabs on the clamping flanges are secured to one of the flanges on the angle member such as by rivets to produce the compression fit. An elongated flat body on the clamp member and a mounting flange on the angle member abut and are secured to the other of the door and door jamb by common mounting fasteners.

The neutral cross bus in a switchgear assembly formed from two sets of side-by-side cabinets includes first and second neutral buses for the respective sets of cabinets. Each neutral bus is made up of a stack of flat conductors oriented horizontally in a main section extending across the cabinets of the set and vertically in a terminal section confronting the terminal section of the other neutral bus. The vertically oriented terminal sections are easily bolted together despite their limited accessibility when the two sets of cabinets are installed side-by-side. The flat conductors of the neutral cross bus are supported in their horizontal main sections by spaced supports formed by planar members with spaced horizontal slots set on edge and mounted by end flanges. The multiple flat conductors of neutral runbacks are interleaved with the flat conductors of the main sections of the cross bus and are supported by partitions having an opening sized to accommodate the maximum number of runback conductors with the remaining portion of the opening blocked by spacers interlocked with each other and the edges of the opening when less than the maximum number of flat runback conductors are used.
