Abstract: A device for low voltage electric distribution includes a set of bus bars for feeding a plurality of outlets protected by a circuit breaker apparatuses, characterized in that it comprises a molded insulating structure comprising two vertical parallel walls (1, 2) separated by a horizontal transversal partition (3), with metal rails (10, 20, 30, 40) inserted in the transversal partition and opening onto either side of said partition. One side acts as a support for the bus bars (11, 21, 31, 41) and the other forming power connections (12, 22, 32, 42), with the tips of said power connection being arrange in accordance with the generatrices of a cylinder with a vertical axis situated in the symmetry plane of the structure. The structure, on the side of the supplies is divided by horizontal partitions defining sockets, with each socket capable of receiving an insulating component (66) bearing clamps (71, 72).

Abstract: An improved plug-in assembly facilitating the tap-off of electrical current from bus bars carried in a busway section that includes opposite side rails and a plurality of plug-in openings formed in each of the side rails in back-to-back association or registration with each other. The plug-in assembly includes a substantially symmetrical insulating base and a door, each swingably connected to the side rail. Ears formed in the side rail adjacent the plug-in opening are aligned with ears formed on the door and a drive screw extends through holes in each pair of ears and into an opening in a support post provided on the side of each base. The screw is fittingly retained in the ear of the side rail while the door and base members fit loosely over the drive screw to permit those parts to swing between an open and a closed position. A metal cover latch is self-retained in one of a pair of symmetrically positioned latch retaining grooves on the front of the base which retains an integral catch portion on the door.

Abstract: An improved housing for a busway system is provided by a two-piece ground bus which includes a generally U-shaped upper section having a top portion and a pair of parallel side flanges extending a predetermined distance and a generally U-shaped lower section having a bottom portion and a pair of parallel side flanges extending intermediate and parallel to the side flanges of the upper section. The main bus bars are retained intermediate the top portion and the bottom portion of the ground bus while also being positioned between the side flanges of the upper section of the ground bus. A side rail is provided on each side of the ground bus. A plurality of fasteners extend along the length of the busway section and connect each side rail with both the upper and lower sections of the ground bus.
