A system and method for connecting supply power to motor control components includes use of a motor control center subunit with moveable supply power contacts. After a motor control center subunit is secured into a motor control center compartment, the supply power contacts may be advanced to engage supply power buses. For disconnection, the supply power contacts may be retracted and isolated from the buses before physical removal of the subunit.

A bus assembly that is structured to be coupled to a multiple pole circuit breaker and to a plurality of horizontally aligned vertical line conductors is disclosed. The circuit breaker has a back side with a line terminal and a load terminal for each pole extending therefrom. At least two terminals are associated with different poles are vertically aligned. The bus assembly includes a first set of line buses structured to be coupled to the line terminals, and include at least one line bus having a horizontal offset, as well as a second set of load buses structured to be coupled to the load terminals and extending in a direction generally parallel to the load terminals.

An offset assembly for a circuit breaker includes at least one two plane member having a first plate and a second plate. The first and second plates are joined at an edge and extend generally perpendicular to each other. The second plate is structured to be coupled to the quick disconnect and the first plate is structured to be coupled to the circuit breaker terminal so that the second plate is not aligned with the centerline of the circuit breaker terminal.

A multiple-hole terminal lug is for a circuit breaker including a load terminal and a conductive terminal extension coupled thereto. The multiple-hole terminal lug includes a mounting portion and a receiving portion having a plurality of receptacles for electrically coupling a corresponding plurality of electrical cables to the load terminal. Secondary mounting holes in the mounting portion align with primary mounting holes in the terminal extension in order to receive fasteners therein and secure the multiple-hole terminal lug in a first or second mounting configuration sloping upward or downward with respect tot the longitudinal axis of the terminal extension.

A shutter assembly for a shuttered bus assembly is provided. The shuttered bus assembly is coupled to a circuit breaker housing assembly. The circuit breaker housing assembly is structured to enclose a circuit breaker assembly. The circuit breaker assembly is structured to move generally horizontally in and out of the circuit breaker housing assembly. The circuit breaker assembly has a plurality of finger connectors extending generally horizontally from the back side of the circuit breaker assembly. The shuttered bus assembly has at least one pair of conductors which extend toward the front of said housing assembly. The finger connectors are structured to engage the conductors. The shutter assembly includes a mounting assembly and a door panel. The mounting assembly is structured to be coupled to the housing assembly. The door panel has at least one opening and at least one door member, the door panel extends across the housing assembly and is disposed between the plurality of conductors and the circuit breaker assembly when the circuit breaker assembly is out of the housing assembly, the door panel is further coupled to the mounting assembly. The at least one door member is disposed in the at least one opening and is coupled to the door panel by a hinge. The door member is structured to move between a first closed position and a second open position. The door member is structured to be moved to the second position by the finger connectors as the circuit breaker assembly is moved into the housing assembly.

An adjustable circuit breaker portion of a multiple contact secondary contact assembly for mating with spaced, non-adjustable contact terminals of a circuit breaker enclosure, which includes a mounting rail and at least two contact modules. The contact modules a disposed on the mounting rail so that the contact modules align with the contact terminals.

A switchgear assembly in which a number of cells housing electrical switching apparatus such as circuit breakers are vertically stacked in a forward compartment has combined arc shield/wire trays between cells for terminating secondary wiring for easy access through front doors on the switchgear assembly and for protecting the secondary wiring from circuit breaker arc gases. The arc gases are deflected by an upwardly and rearwardly inclined panel forming the back wall of the wire tray. A vertical wall forward of the inclined panel mounts a lower horizontal row of terminal blocks forward of an upper row. A wireway has a vertical section in a forward corner of the cabinet beside the vertically stacked cells which communicates with the wire trays, and a horizontal section extending rearward under the top wall of the cabinet. An inclined gutter provides a transition between the top of the vertical section and the forward end of the horizontal section. External wiring enters the wireway either through a bottom access opening aligned with the vertical section or a top access opening in the horizontal section. A depending lip on the rear of the arc shield diverts the arc gases laterally into a vertical chamber behind the vertical section of the wireway for expansion and cooling.

A terminal block has a molded electrically insulative housing with through compartments containing terminal members each having a rectangular planar front section with a tapped hole for a terminal screw and three male terminal blades extending rearward from edges of the rectangular planar front section. The rectangular front section seats on ledges formed by bands integrally molded on opposing side walls of the compartments. Barbs projecting laterally from two facing male terminal blades engage the molded bands to secure the terminal member in the compartment. Partitions extending transversely between the front openings of the compartments provide electrical isolation between the screw terminals, and extend laterally beyond the molded body of the housing at both ends of the partitions to form mounting shoulders, which together with shoulders on projections molded on the housing body, secure the terminal block in an opening in a mounting panel. A cover integrally connected by a living hinge to a wall extending along one end of the partitions controls access to the screw connections on the planar front section of the terminal members.

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.
