摘要： A control center characterized by a metal enclosed upright cabinet having a plurality of vertical bus bars therein, which bus bars are separately insulated and isolated from each other. The assembly of the bus bar and insulation barriers is supported and reinforced by a plurality of vertically spaced braces to prevent lateral movement of the bus bars as well as to hold the insulating barriers in tight surface-to-surface contact with the bus bars.

摘要： An improved electric control center comprising a plurality of drawout type switchgear units housed in a cabinet having incorporated therein an integral air-ventilation duct system of modular snap-fitting construction having at least one air intake opening located at the bottom of the cabinet, one air exhaust opening at the top of the cabinet, and a plurality of branch ducts that communicate with a plurality of tandem compartments that are in stacked relationship and contain the respective switchgear units. The heat generated by the switchgear units and associated bus bars is thus removed from the cabinet by the air flow through the ventilator duct system.
