Some equalizing current would flow along the bus between the pairs of cables, but most would be through the bar. That arrangement ends up looking like a low voltage transformer bushing with 10/phase cables, five on each side.
WebJan 22, 2024 · What is the bus bar rating? The IEEE states a busbar should be rated at the highest amperage passing through any section of the busbar, with a maximum of a 50° C rise in temperature from an ambient temperature of 50° C. This rating method avoids excess terminal temperature at the wire termination. How is busbar rating calculated?
