A versatilely cnnectible bus bar assembly adapted to carry 200-800 amperes in a panelboard or switchboard environment. The assembly includes a plurality of aluminum bus bars having generally rectangular cross-section bases and integrally connected generally U-shaped cross-sectioned plug-on protions extending throughout the length of the bus bars along the top part of the base. The plug-on portion is provided with inwardly directed nubs designed to prevent improper jaw connection. The bottom of each base includes a T-shaped slot extending throughout the length of the bus bar. Each of the bus bars is supported by a plurality of insulating bases, each of which includes a separate channel in engagement with the base of each bus bar. Each bus bar is fastened to each base by a T-bolt and nut. The head of the bolts are received in the T-shaped slot of the bus bars and the nuts are received in recesses provided on the underside of the base. Outwardly directed lips extending throughout the length of the bus bars also aid in the dissipation of heat.
