ABSTRACT:
The outer surfaces of adjoining electrical busway side frames are shaped to define a protruding rail extending along the vertical axis thereof. A pair of recessed channels formed within the inner surfaces of the side frames of an intervening busway joint receive the busway rails at opposing ends thereof. Clearance arranged within the respective busway joint channels allows lateral movement of the busway side frames relative to the busway joint. Slots are provided on the busway joint side frames for visual indication of the position of the busway rails.
