A bus bar assembly (110) includes a pair of source and return bus bars (118,116) mounted on at least one of the side edges (108,112) of a daughter card (102) and electrically connected by arrays of terminals (172) to power circuits of the card, for use in a system for distributing electrical power t

A bus bar assembly (110) includes a pair of source and return bus bars (118,116) mounted on at least one of the side edges (108,112) of a daughter card (102) and electrically connected by arrays of terminals (172) to power circuits of the card, for use in a system for distributing electrical power to the daughter card module (100) upon insertion into a card cage (10). The pair of bus bars (118,116) is insulated by a cover (120) having a rail (126) for following the guide channels (18,20) of the card cage at each card location. Rearward ends of the bus bars have blades (122,124) which are received into receptacle contacts (46,44) mounted in the card cage above and below the backplane (14), which are mounted at each card location and electrically connected to source and return busses (68,58) of the card cage, with the receptacle contacts (46,44) preferably being float mounted to be easily incrementally moved upon blade receipt during card module (100) insertion.
