I'm unsure about how to go about handling this. I was given the following info, 33kw, 230v, 3ph. The service provided is 3 ph. 240/120. I can't find a nameplate anywhere on the machine. I spoke to the sales rep for the furnace and he sd that is all the info he has to provide. What calculations should I use to figure out what wire size to use.
