Can I use 12/3 Nm to feed a 3 phase piece of equipment? I am bidding a job I guess you would call it commercial but it is a stick framed building with drywall as an interior finish. It is considered food processing but is just short of pharmaceutical. Besides general purpose receptacle and lighting outlets there are two 15 amp 3 phase pieces of equipment. Can I use NM to wire these. The wiring will not be exposed. I will poke out of wall into back of disconnect and then flex over to machine. I am sure I can use Nm in the type of construction I am dealing with is there any thing I am not thinking of? Can I mark my white wire blue and use it for three phase.
Thanks
