Always write capacity of motor in HP. your motor efficiancy
is 70%. with 100% efficiancy should be 145A with 380V.
please check the voltage & Current with load on motor
terminal. and use cable (in Sqmm) half of the running
current. I think your cable voltage drop should be 15 to
39V as per loadind.
