WebJul 6, 2015 · Re: Current carring capacity of copper bus bar. 240000 amps only if the driving source impedance is low !! even in heavy power distribution 200 kA is considrered a very high short circuit fault current. 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.
