In case of 3 phase 4 wire PCC or MCC. Breaker ACB selection shall be 4 pole breaker or 3 pole breaker. ?

HOW SHOULD WE CALCULATE THE SHOT CIRCUIT THERMAL EFFECT FOR WIRES& CABLES

[@suchayan-vu2ld]

0.859 sq.inch=554sq.mm, provided Busbar 1000sq.mm>554sq.mm; Hence 1000sq.mm is more than the required minimum size busbar.

Please mention the reference material name for the formula

[@brameshe]

can you provide the formula for copper busbar & standards

[@mrstrong5695]

Using your equation and your input data, the correct answer is 8.59 sq inches, and NOT 0.859 sq inches !
Please check and confirm..

[@subekthakur6865]

Yes..... You are right

[@nareshram9922]

1000 sqmm = 1550 sq inches
