Abstract: A busway and a door assembly for use with the busway are described. The door assembly provides access to the conductive busbars through openings in the busway housing. The door assembly includes an insulator plate having openings therethrough for access to the busbars. The insulator plate includes two hinge grooves disposed on opposite edges of the insulator plate. Additionally, the door assembly includes a dual-hinged door which includes a pair of hinge rods adapted for engagement with the hinge grooves. By pivotally rotating on the first hinge rod within the first hinge groove, the door may be opened to a first position. Conversely, by pivotally rotating on the second hinge rod within the second hinge groove, the door may be opened in a second direction. Once in either open position, the door cannot be removed from the insulator plate. Additionally, insulator stabs extend from the insulator plate and are disposed between the busbars to prevent arcing between the exposed areas of the busbars.
