    Abstract: An assembly is provided to facilitate connecting of a current take-off unit to a plurality of bus bars as normally found in an electrical distribution system. The assembly includes pairs of jaw members disposed within a housing. The corresponding ends of each pair of jaw members project from the housing and clampingly engage a bus bar. The corresponding opposite ends of said pair of jaw members engage an elongated connector piece which projects from the housing and is adapted to be connected to the current take-off unit. The assembly is provided with a spring for providing adequate contact clamping pressure between the jaw members and the bus bar. An adjustable means is also provided for the jaw members for attaining a higher contact clamping pressure and thus a lower contact resistance even under severe operating loads. An insulating element substantially encompasses a portion of the pair of jaw members, a portion of the connector piece, the biasing spring, and the adjustable jaw member tightening means disposed within the housing. An adjustable adaptor member of nonconductive material is disposed within the housing and is in engagement with the jaw member tightening means whereby the latter may be manually adjusted relative to the jaw members to increase the clamping pressure thereof on the bus bar. The adaptor member has a portion thereof accessible from the housing exterior whereby manual force can be applied thereto to effect manual adjustment of the jaw member tightening means.

    Abstract: The joint structure includes a pair of joint tie channels with gaskets and a pair of joint covers with gaskets, one of the joint covers having a captive nut and the other of the joint covers having a removable closing cap for providing access to a joint bolt threaded into the captive nut. For horizontal edgewise mounting of a pair of bus duct sections, the gasket material is removed from the bottom tie channel. For horizontal flatwise mounting, the closing cap is removed from its joint cover, which is disposed at the bottom of the joint. For vertical mounting, the gasket material is removed from the lower edges of both joint covers.

    Abstract: Methods of making insulated bus bars using flat, non-selfconforming insulating film as insulation. One or more strips of insulating film are fed through various work stations in which the strips are formed into a generally U-shaped cross section, heated on the inside of the U-shaped cross section, formed into a sleeve corresponding to the shape of a bus bar and having overlapping longitudinal edge portions, heated on the outside, cooled, and cut to length. A bus bar is then inserted transversely in the formed sleeve.

    Abstract: A SECTION OF THE DUCT HAS A HOUSING OF RECTANGULAR CROSS SECTION CONTAINING A PLURALITY OF FLATWISE-STACKED POWER BUS BARS AND HAVING RECURRING ACCESS OPENINGS IN OPPOSITE SIDE WALLS EACH OF WHICH PERMITS EITHER A LOWER-CURRENT PLUGIN UNIT OR A HIGHER CURRENT TAP-OFF UNIT TO BE SELECTIVELY CONNECTED THERETHROUGH TO THE BUS BARS. HOOD AND DOOR ASSEMBLIES ARE PIVOTED ON THE HOUSING AT THE RESPECTIVE ACCESS OPENINGS AND EACH COVERS ITS ASSOCIATED ACCESS OPENING WHEN IN CLOSED POSITION. AN INSULATOR, SECURED TO THE INNER SIDE OF EACH HOOD, HAS A PLURALITY OF RELATIVELY SMALL OPENINGS PROVIDING ACCESS TO THE BUS BARS BY JAWS OF A LOW-CURRENT PLUG-IN UNIT WHEN THE DOOR IS OPEN. WHEN EACH ASSEMBLY IS IN ITS OPEN POSITION, THE INSULATOR SECURED TO THE HOOD THEREOF IS REMOVED FROM THE BUS BARS TO UNCOVER A RELATIVELY LARGE CONTACT AREA ON EACH BUS BAR. A GENERALLY RECTANGULAR MOUNTING FRAME MAY BE RELEASABLY ATTACHED TO THE HOUSING AT EACH OF SELECTED ONES OF THE ACCESS OPENINGS, AND A HIGH-CURRENT TRAP-OFF UNIT MAY BE REMOVABLY ATTACHED TO EACH MOUNTING FRAME. EACH TAP-OFF UNIT HAS A JOINT STRUCTURE WHICH, WHEN THE ASSOCIATED HOOD MEMBER IS IN ITS OPEN POSITON, CAN EXTEND THROUGH THE ASSOCIATED ACCESS OPENING AND INTERLEAVE WITH THE RELATIVELY LARGE CONTACT AREAS ON THE BUS BARS. JAWS OF GROUND BUS BAR CONNECTOR EXTEND THROUGH THE RESPECTIVE ACCESS OPENINGS FOR SELECTIVE ENGAGEMENT WITH A GROUNDING BLADE OF THE PLUG-IN AND TAP-OFF UNITS.
