A combination DC/data bus assembly for power converter equipment racks includes a pair of side-by-side vertical DC bus bars forming a slot between them. Extruded insulating strips carrying data bus bars are mounted in the DC bus bars so that the data bus bars face each other across the slot. Channels are formed in the front faces of the DC bus bars. A connector mounted on the power converter chassis has male DC contacts that engage the channels, and a male data contact assembly that slides into the slot to make contact with the data bus bars.
