not at all.
bcoz if we give single phase supply to the motor.,it won't create rotating magnetic flux. rotataing magnetic flux is must for the motor to run.

We have a distribution transformer of 750KVA/11kv/440v and an AVR (Servo Stabilizer) of 750KVA on the LT side of distribution transformer. Also we have an ACB of 1200A on the output of distribution transformer (that is on the input of AVR). We want to have an MCCB on the output of AVR. What should be the rating?
