This patent application teaches a busway that can be fabricated with an insert that is a long flat insulating strip with conductors installed in it, up to hundreds of feet if desired, and rolled up for shipment and handling. When installed, shell segments are installed end-to-end, then the insert is unrolled, folded into an inverted “U” shape, then installed in the shell segments as a continuous insulator and conductor. The inverted “U” shape tends to repel moisture that may enter from the top, and no segment-to-segment connectors are needed.
This patent application is a continuation in part of a provisional patent application Ser. No. 61/534,308 of the same name filed Sep. 13, 2011. Priority is claimed to its filing date, and this patent application is incorporated herein by reference.
