Abstract
A multiple-door switchgear cabinet includes a cabinet housing containing electrical equipment and being connectable to a power source. Doors attached to the cabinet housing provide access to the electrical equipment and include a first door and secondary doors. The first door, when closed, provides for electrical continuity through a main electrical power switch, and removes electrical continuity when open. A mechanical interlock controls the order in which the doors are closed. The mechanical interlock is mounted to the cabinet and is in contact with the doors when they are closed, the interlock being biased by a biasing device to bear against the first door when any of the other doors is opened. A locking bar is movably attached to the first door, and releasably attached to the secondary door. wherein attachment to the secondary door prevents both doors from inadvertent opening.
