Abstract: A wiring assembly for mounting on an exposed surface of a wall or wall panel to supply electrical power to the wall or wall panel. The wiring assembly includes a plurality of conductive bus bars and an insulating support having a base and a plurality of generally parallel dividers extending upwardly from the base to define a plurality of slots therebetween. Each slot is configured to receive a conductive bus bar therein. The support is coupled to said exposed surface. The assembly also includes at least one cover and at least one outlet coupled to the support. The at least one cover and the at least one outlet are situated over the plurality of dividers to shield the plurality of conductive bus bars situated in the plurality of slots. The at least one cover and the at least one outlet are adjacent one another on the support.
