ABSTRACT:
The invention relates to single, paired opposite phased and multiple stacked insulated flexible or rigid bus bar electrical conductors of copper or aluminum assembled side by side (optionally in a factory or at installation site) as high current density circuits into open trays of substantial length and covers to totally enclose a heat transfer tray co-extensive with the tray and having clamps extending across the tray to secure the cover to the tray and urging the cover upon conductors or conductor joints in the tray by tightening single bolts per clamp. Also, the invention involves making externally operable end to end overlap compression circuit joints of bus bar conductors simultaneously with one or more single bolt clamps for each single, paired phase and multiple stack, electrically insulated apart and supported within the metal tray. Another embodiment consists of insulated bus bar conductors assembled as paired phase circuits into bus tray having one conductor of each paired phase bared, folded and extended into protected access at spaced intervals for engagement of plug-in and bolted branch circuit loads.
