An electrical distribution apparatus (102) includes a backplane (108) for supporting a plurality of electrical devices (116), a bus bar assembly (106) coupled to the backplane, and a frame (110) that supports the backplane. The electrical distribution apparatus also includes at least one positioning member (302) that facilitates positioning the backplane relative to the frame. The at least one positioning member at least partially supports the backplane such that the backplane is positionable between a first position and a second position. The backplane contacts the frame in the second position.
