Answer / divakaran a
P=1.732xVxIxP.F
30KW=1.732x415xIx0.8
I=30000/(1.732x415x0.8)
I=52.17 AMPS
sO the current drawing from the motor is 52 amps (Theoriticaly)
in practical the motor may draws more current as based on the load.

Answer / vipul kumar rai
P=1.732xVoltage x I(current )xPower Factor
30KW=1.732x415xIx0.8
I=30000/(1.732x415x0.8)
I=52.17 AMPS
as per thory 52.17A current draw.
so 56A is approx correct.
