Abstract
A copper busbar is created in H-shaped cross-section by assembling a pair of elongated copper bars of rectangular cross-section to one or more conjoining copper webs of U-shaped cross-section. The bars and web legs are pre-punched with series of holes accommodating bolts clamping the bars to the web in parallel spaced relation. The bridging portion of the web is also pre-punched with a series of bolt holes facilitating the implementation of the busbar as a riser bus in electrical distribution equipment, such as switchboards, switchgear, and the like.
Claims3

- a pair of elongated bars of flat, rectangular cross-section;
- and
- a plurality of elongated webs having combined lengths less than said bars, said webs being bolted to said bars in longitudinally aligned, gapped relation
