The plurality of mounting plate members includes at least a bottom mounting plate member and at least one movable mounting plate member. Each mounting plate structured to support one or more electrical components. The plurality of vertical walls include a front wall coupled to, and extending generally perpendicular to, the base plate member, a first side wall coupled to, and extending generally perpendicular to, the base plate member, a second side wall coupled to, and extending generally perpendicular to, the base plate member, a back wall coupled to, and extending generally perpendicular to, the base plate member.

Abstract: A door comprising a panel member having a first side and a second side and an opening therebetween; a hinge disposed adjacent to said opening; a control module; said control module hingedly attached to said panel by said hinge; said control module includes an electronic unit which has a first side; said control module being pivotable on said hinge between a first position wherein said electronic unit first side is visible through said opening from said panel first side and a second position where said electronic unit first side is visible from said panel second side.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A heater for the middle, bus bar compartment of a switchgear cabinet is inserted from the rear compartment through an opening in a vertical panel at the rear of the middle compartment and is supported within the middle compartment by a bracket cantilevered from the panel. The bracket is U-shaped with a horizontal base and a pair of upstanding side walls forming rails on which the heater slides. The heater includes an inverted U-shaped guard over the heater element forming downwardly facing slots which engage the bracket rails. The guard and the bracket are perforated for convective circulation of air induced by the heater.

Abstract: 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.
