ECN Forum Forums General Topics of the Trade General Discussion Area 240 volt 3 phase w/high leg

If the machine is receptacle-/cord-connected, there is no NEMA-standard 5-wire devices of that voltage rating. A "neutral conductor" is needed, and sized based on the control-circuit fuse, if any. Agreed it is a grey area.

Nota Bene: This is not a code-defined mutliwire branch circuit, for that needs equal ø-n voltages.
