I am trying to size some conductors. The voltage is 12.4KV. The conductors are feeding a 2,500KVA transformer.
If I size the conductors to the transformer, is my amp calculation 2,500KVA / 12.4KV = 201 amps? (use 250KCMIL conductors)
Or is it 2,500KVA / (12.4KV X square root of 3) = 117 amps? (use 1/0 conductors)
Which is it?
Thanks in advance. I appreciate any help.
