What is Bus Bar Design Calculation for 50KA about?

The design calculation for a bus bar indicates a fault level of 50KA for 1 second, requiring a minimum cross-sectional area of 645 mm², while the actual bus bar used has a cross-section of 2000 mm². Dynamic forces calculated for the bus bar during a short circuit test are approximately 901.22 Kg f, which is well within the breaking strength of the bus bar support at 2730 Kg f, providing a safety factor of 3.0. Overall, the bus bar support is deemed suitable to withstand the specified fault level.
