Abstract

A control center characterized by vertical bus bars supported by dielectric insulators which are disposed in vertically spaced pairs along the bus bars and which are molded with a configuration to accommodate bus bars of various shapes and sizes.

Claims

1. A control center for distributing electric power from a power supply source to power consuming devices, comprising a cabinet having a plurality of vertically spaced compartments on the front side of the cabinet, a plurality of vertical, horizontally spaced, bus bars in said cabinet, insulating means mounting the bus bars with the surfaces of each bus bar being in surface-to-surface contact with the insulating means, the insulating means comprising a sheet-like member on each side of the spaced bus bars which members have interfitting portions including a flange-receiving groove in one member and a flange in the other member and said interfitting portions extending between each pair of adjacent bus bars, a circuit interrupter structure in at least one compartment and movable transversely into and out of position adjacent to the bus bars, each bus bar comprising a portion disposed in a plane aligned with the direction of movement of the circuit interrupter, said structure comprising a contact member engaging a bus bar, each sheet-like member also comprising wall means forming horizontally spaced vertical ribs extending away from the other sheet-like member, the vertical ribs in one sheet-like member being aligned with the vertical ribs of the other member, each pair of aligned ribs forming a vertical chamber receiving said bus bar portion, and said bus bar portion in at least one of said ribs wherein one rib of a pair of aligned ribs extend further on one side of one sheet-like member than the other rib of said pair extends on the opposite side of the other sheet-like member, and whereby said ribs on said sheet-like members can accomodate bus bars of many different shapes.

2. The control center of claim 1 in which each bus bar comprises an L-shaped cross section including a body portion and a leg with the body portion extending between the sheet-like members, and the leg disposed in one of each pair of ribs.

3. The control center of claim 1 in which each bus bar comprises a Z-shaped cross section including a body portion and two legs with the body portion extending between the sheet-like members, one leg disposed in one of each pair of aligned ribs, and the other leg disposed in an oppositely extending rib of a different pair of ribs.
