Abstract
The electric busway busbars within a plug-in busway system are covered by an insulating cover to prevent inadvertent contact when the busbars are energized. To allow contact with the busbars for busway plug connection, the insulating cover is arranged for automatic exposure of the busway plug access openings by means of a sliding shutter. The shutter automatically returns to the closed position immediately upon removal of the busway plug.
