Abstract

A back-wiring board that connects to a main circuit board of a power distribution system. The back-wiring board includes a plurality of connectors configured to mechanically secure to a plurality of bus bars. The connectors of the back-wiring board are further configured to receive a voltage signal from the plurality of bus bars and to transmit the voltage signal to the back-wiring board. The back-wiring board also includes a plurality of wire-wrap pins integrated into a surface of the back-wiring board, wherein the wire-wrap pins are configured to receive data input signals. The back-wiring board includes a right-angle connector configured to couple the back-wiring board to the main circuit board.
