Abstract
In a busway having plural busbars disposed with their broad sides in face-to-face relation, the ends of longitudinally aligned outside busbars are cut at complementary angles to create a single edge connecting segment for each busbar which extends through a phase transposition zone. Upper and lower transverse connectors are welded at their opposed ends to transversely aligned edge connecting segments to effectively reverse the phase positions of the busbars upstream and downstream of the transposition zone. 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.
