ABSTRACT OF THE DISCLOSURE A control center characterized by an upright cabinet in which a plurality of vertical bus bars are disposed which bus bars are encased in a pair of planar molded barriers of insulative material which are in tight surface-to-surface contact with the bus bars for extracting heat therefrom. Openings are provided in the barriers to enable access to the bus bars at spaced intervals corresponding to the spac- ing between contacts on circuit interrupters located within the cabinet. Shutter means for closing the openings when the circuit interrupter is withdrawn from the cabinet are provided and the shutter means comprises a level projecting into the path of travel of the circuit interrupter for moving the shutter means to an open position when the cir- cuit interrupter is inserted into the cabinet.
