The answer is yes. That is the only way to do it. A wye or star motor just describes the way the motor is wired internally or configured in the make up box, it has nothing to do with the circuit powering it.Can i supply 3 core cable without neutral to a 3 phase Y motor load? this is a client request,
I think no as Per 250.24(C), am i correct?
I have noted that ground and neutral are sometimes confused with each other.All motors that I've encountered do not require a neutral connection to function. The motor might be internally connected in 'wye' but is supplied with only the three phase conductors, no neutral conductor.
If the _load_ requires a neutral for whatever reason, then you must provide that neutral conductor. But I would be very surprised if a 'motor load' actually requires the neutral.
Article 250 is about grounding, and 250.24 is about bonding the grounded conductor; relevant for the service but not for supplying an individual load. In addition to the 3 phase conductors, your motor load will require and EGC.
