First of all calculate the full current in running position
.Then check the incoming voltage and finally check the power
factor.i.e. P.F. and then use the formula:
Total current*1.732*volts*P.F.=Total load(W)

what is sustainable current of any conductors . a bare busbar or pvc cable has different sustainable current .
