Abstract
A control center characterized by vertical bus bars having electrically insulating covers thereon which covers are in surface-to-surface contact with all surfaces of the bus bars except for spaced areas where connection is made by conductors for load distributions. In addition, each pair of spaced bus bars are isolated from each other by interfitting portions of the covers which portions are coextensive with the bus bars so that resistance to tracking and arcing between the bus bars is maximized.
