Currently looking at a job to install power for welders. I asked for the size of the welders and customer has replied with MIG 32A 3Ph = 14KVA.
So i can work out total loadings for the installation have a i done the following sum correctly?
14kva X PF of 0.8 = 11.2kw
A= 11.2 x 1000/415 x 1.732 x PFat 0.8
I get 37.39A so 12.46 A per phase?
