摘要： A tap-off base assembly of the present invention provides protection against the ingress of dust and liquids into an electrical busway distribution system of the type having access openings for receiving power tap-off devices. The tap-off base assembly includes a base molded from an electrically insulating material and a pivotally attached door. A tap-off opening seal is placed on the housing around the tap-off opening. The base is slidably received in the busway tap-off opening such that the seal is compressed thereby sealing the tap-off opening. The base has a planar outside surface which includes a number of access openings. Each access opening provides access to one the electrical conductors contained within the busway housing. The door may be selectively moved between an open position which provides access to the electrical conductors and a closed position which prohibits access to the conductors. The door also has a flange around its perimeter 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 base and the sealing ribs are pressed against a gasket in the planar outside surface of the base which 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 securing the door in its closed position.

摘要： A oiltight lay-in wireway comprised of wireway sections with hinged covers and a joint connector between the covers of two adjacent wireway sections. The covers overlay the joint connector. The joint connector has a free floating hinge connecting it to the wireway sections, allowing the cover to provide the main compression force on the joint connector gasket. A bolt with a splined shoulder provides a grounded connection between adjacent wireway sections while still allowing the joint connector to float freely. The compression force on the joint connector is exerted by the covers which are held closed by clips on the wireway sections. An oil resilient gasket provides a seal between adjacent wireway sections, between the joint connector and wireway sections, between the cover and joint connector, and between the cover and wireway sections. Raised ends on the cover contact the joint connectors while still maintaining a seal with the wireway sections.

摘要： A floor construction includes a concrete floor having a main duct embedded in the concrete floor. The main duct has a bottom and a top, with the top being covered by the concrete floor. A service fitting includes a service box and an auxiliary duct means. The service box is located adjacent a side of the main duct and has a plan area and a capacity substantially equal to at least that plan area times a depth of the concrete floor above the bottom of the main duct. The auxiliary duct lays transversely across the top of the main duct and is attached thereto for providing a passage for wiring from the main duct to the service box. The main duct preferably is a multi-cell duct, and the auxiliary duct includes dividers dividing the auxiliary duct into passageways corresponding to the cells of the main duct. This construction provides for a greatly increased capacity for the service fitting in concrete floors of minimum depths.
