Abstract: Main circuit breakers and/or tie circuit breakers are connected by upper and lower disconnects to upper and lower sections, respectively, of split risers in a low voltage switchgear assembly. An upper horizontal bus is connected to the upper sections of the split risers while a lower horizontal bus is connected to the lower sections. However, with the main or tie breaker mounted in the "C" position of a switchgear section, the gap between the upper and lower sections of the split risers is positioned vertically such that one of the phase conductors of the lower horizontal bus is above the gap. A unique connector extends downward from this phase conductor and is connected to the corresponding phase of the lower section of the vertical bus through the lower stab which engages the lower disconnect for the main or tie breaker.

Abstract: A panelboard/switchboard assembly for accommodating bolt-on modules, plug-in modules and lugs. The panelboard/switchboard includes vertical, edge forward bus bars having a plurality of openings formed therein. The edge forward alignment allows plug-in modules to be mounted to the bus bars. The openings in the bus bars receive bolts for mounting straps to the bus bars and for mounting lugs to the bus bars. The openings have a shape having at least one linear element and receive a bolt having an anti-rotation portion with a similar shape. The interference between the opening and the anti-rotation portion of the bolt prevents the straps, and the modules connected to the straps, from rotating.

Abstract: A bus bar panel system utilizes a quick acting and simplified fastening system for making connections. The bus bar is preferably pre-perforated along the edges, although holes may be drilled at the time of fastening. The fastening system uses a stud having threads on one end for receiving the usual washers and nut. On the other end, usually away from the installer, the stud is provided with flats which engage an open slot or yoke on a keeper clip. The clip has a gauge flange to engage the edge of the bar or clamp through which the stud extends. The transverse dimensions of the open slot are related to the flats and the length of the slot to the distance of the perforations from the edge of the bar. The clip also includes a spring section which grabs the end of the stud holding the clip in place so that the installer has both hands free to secure the nut and washers.

Abstract: A power busway distribution section length which may be adjusted before, during, or after installation to better facilitate proper busway location and reduce installation and modification costs. The section length comprises two busway stubs which slide independently between a center busway splice-plate joint. Overlapping sheet metal enclosures are used to provide protection from inadvertent contact with live bus bars and allow the busway section length to be adjusted to a discrete length.

Abstract: An electrical power distribution busway joint is shown and described. The joint is configurable to electrically couple the phase busbars, the neutral busbar(s) and the ground busbars of adjacent busway sections. Each of the phase and neutral busbars from adjacent busway sections are in electrical contact with the inside surfaces of a pair of rectangular connector plates. The connector plates are fabricated from a conductive material to include at least one opening and a spacing tab fabricated from at least a portion of the material removed from the plate to form the hole. The spacing tabs of the plates cooperate to maintain a space between the plates which facilitates insertion of a busbar into the space. The tabs also prevent over-insertion of busbars into the joints which may damage insulating material within the joint. The outside surfaces of the connector plates are each engaged by a rectangular insulator formed from a section of pultruded insulating material.

Abstract: An improved packaging scheme for a CPU of a main frame computer improves the performance while at the same reduces the cost of manufacture of the main frame computer. A single packaging technology is used to package the whole CPU and eliminates cable connections inside the CPU. Surface power bus technology permits the fabrication of a module with chips mounted on both front and back sides of the substrate. The surface power bus is installed on one or both sides of the module surface and derives power directly from the power cable and distributes power to chip sites directly. In a specific implementation, a uni-processor CPU with chips mounted on both surfaces of the substrate and power fed from the surface power bus results in improved processor package density and system performance.

If the busway includes two inside busbars, phase transposition is achieved in similar fashion. Once insulatively coated, the phase transpositioned busbars are nested together to create a compact transposition zone having a transverse dimension no greater than the busway therebeyond.
