RE: star-delta start up
If this is true, the current should be about 2 x the rated current of the motor, then the problem is probably that you are trying to start a load that requires a high starting torque and the star/delta starter is not correct for this application.
What is the load that you are trying to start?
Best regards,
Mark.
