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?

With a 1000 kVA feeder transformer the typical load current is 1000 0000 / (3 * 240) approx 1400 amps per phase. WebMar 3, 2010 · The current flow would be through the 1/4" dimension of the bar and not along the bar. 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. church choir mysteries
