Apparatus and method for connecting a power supply to multiple backplanes within an electronic equipment cabinet

An electronic system has a power supply, multiple backplanes, and a bus bar assembly electrically interconnected between the power supply and the multiple backplanes. The bus bar assembly includes a power supply member that couples to a power supply and a backplane member that couples simultaneously to multiple backplanes. The backplane member defines multiple rows of holes. Each row of holes includes at least two holes. The bus bar assembly further includes a set of fasteners that fasten the power supply member to the backplane member in order to provide a conductive path between the power supply and the multiple backplanes. The multiple rows of holes defined by the backplane member enable the backplane member to fasten to power supply members having different designs for flexibility.
