摘要：A tap-off base assembly of the present invention provides protection againstthe ingress of dust and liquids into an electrical busway distribution system of the typehaving access openings for receiving power tap-off devices. The tap-off base assemblyincludes a base molded from an electrically insulating material and a pivotally attacheddoor. A tap-off opening seal is placed on the housing around the tap-off opening. Thebase is slidably received in the busway tap-off opening such that the seal is compressedthereby sealing the tap-off opening. The base has a planar outside surface which includesa number of access openings. Each access opening provides access to one the electricalconductors contained within the busway housing. The door may be selectively movedbetween an open position which provides access to the electrical conductors and a closedposition which prohibits access to the conductors. The door also has a flange around itsperimeter and a sealing rib which extend outward from the inside surface of the door.When the door is in the closed position the flange overlaps an edge portion of the baseand the sealing ribs are pressed against a gasket in the planar outside surface of the basewhich surrounds the access openings thereby sealing the access openings and preventing
the ingress of dust and liquids into the busway housing. A latch is provided for securingthe door in its closed position.
