SWITCHGEAR ASSEMBLIES WITH MOLDED SUPPORT MOUNTING BUS BARS EXTENDING THROUGH BARRIERS BETWEEN SIDE-BY-SIDE CABINETS

摘要

The cross buses extending through side-by-sidecabinets in a switchgear assembly are mounted on the metalcabinet frames by supports having a molded body with a busbar mounting surface laterally spaced from a supportmounting surface to form a gap between the bus bar and themetal frame. A planar barrier inserted between the cabinetshas a cutout aligned with this gap. The molded supportfurther has a barrier surface which extends across the gapand blocks the cutout. The barrier surfaces of supportsmounted on side-by-side cabinets abut and parallel flangeson the molded bodies adjacent the barrier surfaces formgrooves in which the planar barrier is clamped.
