Hi All, I have a question on busbar installations. With regard to busbars in parallel. I can see in both NEC and CEC installation requirements of conductors is clear, but with regard to busbar, there is some data missing. For overall lengths of busbars, when in parallel, do the lengths have to be the same? I know current capacity is based on width and height, but can't see anything on lengths. For the installation I am looking at using Flexible busbars and trying to see if the lengths would have to be the same (like cables/conductors). Any help with code references would be appreciated.

Bussing internal to equipment is covered by the Listing requirements for that equipment, not National codes.
But the theory is the same: parallel conductors should be the same length.

Busbars that you install to interconnect equipment are still conductors, so if they are in parallel, they need to be same length
