US 2001/0034149 A1 · Draw out unit

Abstract

A draw out unit mounts switching devices within a switchgear unit and electrically connects the switching devices to electrical bus bars. A cutout portion in draw out unit receives an insulative housing for a lug adapter assembly. Lug adapter assembly includes a plurality of clip assemblies positioned within receptacles formed on insulative housing. Each clip assembly slidably accepts one bus bar, thereby providing an electrical connection to bus bars. Lug adapter assembly also includes lugs, which are electrically connected to clip assemblies via a conductive bar. Lugs accept wires, which extend from lugs in switching device. Lugs are arranged to minimize bending of wires.
