Definitely consult a local sparky. If you are going 1ph 120/240v pretty much anybody can handle that.

I don't know about your area or what else you have going on in the shop. Around here small businesses that are using a bit of power typically get a 320A service.
320A is the largest non commercial service our local companies will provide. Usually a couple of 200A 42spc panels or large panelboards go inside the building.

Some thing is wrong here. I'm guessing you need to talk to someone more knowledgeable at the DC company (or go with the equipment nameplates, etc.). In the USA, you get 208 or 240 when it comes to 3 phase, that's it. Lots of equipment say 230 but this is do compliance with a really old standard. It means 240. Most things can run on both, but if it's sold in the US, I would be astonished if it did not run on one of those. Something in between makes no sense. Some imported machines (Japan) don't like 240 and you need a transformer to take the edge off for them (208).
