I had a similar one to this yesterday, 11 kw was wired in star delta and we were putting a VSD on it. Nothing on the plate about wether it would run in star or delta. Possibly naively i assumed delta for the size of the motor but it wouldn't run. Changed it to star and run a treat.
Is there any particular rule for sizes of motor and star or delta ?
