摘要： A multi-door enclosure for housing electrical equipment has a mechanical interlock device that interacts with a main primary door of the enclosure and the existing latch mechanisms of each of the remaining secondary doors to prevent such secondary doors from being opened unless the primary door is first opened. The interlock includes a lever arm that engages and is displaced by the primary door when closed. Such movement of the lever arm is transmitted via a mechanical linkage system to move one or more latch disabling members into disabling relation with the latch mechanisms of each of the secondary doors in order to retain the latch mechanisms in their latched positions and thereby lock the secondary doors in the closed position. Opening the secondary door allows the lever arm to return to its initial position which in turn retracts the latching members and allows unlatching and opening of the secondary doors.
