Answer / birinchi narayan boruah

It depends upon designed parameter of the motor. Generally
All 3 phase Induction motors take starting current 3 to 5
times of the full load current. 200 Amps incomer can be used
for the same but its better if you go for higher rating.

Answer / prashant

P = 1.732VICosA

I = 148A
Starting current of a motor is 1.25 - 1.5% of I so you
should be able to run the motor but it will be preferable
if yu can go for the next higher rating
