Abstract
A draw out unit (10) mounts switching devices (12,14) within a switchgear unit and electrically connects the switching devices (12,14) to electrical bus bars (16). A cutout portion (30) in draw out unit (10) receives an insulative housing (32) for a lug adapter assembly (34). Lug adapter assembly (34) includes a plurality of clip assemblies (36) positioned within receptacles (38) formed on insulative housing (32). Each clip assembly (36) slidably accepts one bus bar (16), thereby providing an electrical connection to bus bars (16). Lug adapter assembly (34) also includes lugs (40), which are electrically connected to clip assemblies (36) via a conductive bar (42). Lugs (40) accept wires (44), which extend from lugs (46) in switching device (12). Lugs (40) are arranged to minimize bending of wires (44). Clip assemblies (36) each include a plurality of staggered clips (104, 106). Upon insertion of draw out unit (10) into the switchgear, each bus bar (16) is received by the contact arms (116, 118) of first clip (106), before being received by contact arms (116, 118) of the second clip (104).
