An electrical distribution switchboard including a multiphase horizontal main bus and a multiphase vertical riser bus. Each individual horizontal phase conductor comprises a plurality of spaced parallel bars connected to the corresponding individual vertical phase conductor through an extruded aluminum block having a plurality of grooves formed in each side to receive the spaced parallel bars. The bars are welded in the grooves and the connector welded to the individual vertical phase conductor.

Bus connector for welded electrical switchboard bus structure

An electrical switchboard including a horizontal main supply bus and a vertical riser bus mounted within a cabinet structure. The conductors of the vertical riser bus include front and rear flanges connected by a web portion to form an I-shaped cross section. Line side stab connectors are mounted directly to the front flanges using bolts and press nuts seated in the front flange. Riser support members and load side extension support members are mounted upon the rear flanges.

Electrical switchboard apparatus including double-flanged vertical riser

An electrical distribution switchboard including a multiphase horizontal main bus and a multiphase vertical riser bus. A plurality of protective members are provided, each being vacuum formed from a thermoplastic carbonate-linked polymer material. Separate protective members are provided for each individual phase conductor of the horizontal and vertical bus.
