Abstract

A bus bar assembly comprises a first bus bar and a second bus bar. Each bus bar comprises a bridge flange having a first side and a second side, top and bottom flanges extending from the first side of the bridge flange, and an interface flange extending from the second side of the bridge flange. The bus bar assembly further comprises a first insulation layer positioned between the top flanges of the first and second bus bars and a second insulation layer positioned between the bottom flanges of the first and second bus bars. Each of the top and bottom flanges comprises a plurality of mating devices coupled thereto. The top flanges of the first and second bus bars and the first insulation layer are fixedly joined together. The bottom flanges of the first and second bus bars and the second insulation layer are fixedly joined together.
