ya it is commercial its in a industrial park in Anderson (13 miles south of redding)
they have a bunch of ind/com buildings close together so it may not be too hard to get IDK I need to call the electric company and get a price the only down side is I would not be able to run it anywhere else if I moved shops

Before you move shops then you'd want to make sure you had 3-phase power supplied to it beforehand.
IMO converters are just energy hogs to get something done.
Are you sure it's a dedicate 3-phase? If it's a true 3-phase motor it will take L1, L2, and L3 wires and a ground... with no neutral.
If you've ever looked up anything about 3-phase, it uses 3 different currents each out of phase by 120 degrees, and the motor uses those to create a true magnetic field.
If it doesn't use all three phases, it's not a true 3-phase, and you may can purchase a different tap for the back of the machine that allows it to run single phase 240v.
The reason I don't think this is true 3-phase is the fact that it requires 240v... 240v three phase isn't usually popular in shops because it still has 120v lighting, outlets, and computer circuits...
In normal 3-phase it's 208/120 or 240/139 (if my numbers serve me right)... and some motors / heating elements only work 75% efficiently at 208v.
To get a true 240/120 you're going to need what they call a high delta leg on your transformer setup, and when purchasing a machine most shops don't have this.. they have a 208Y/120 instead of a high delta.

Yep, just pull the panel.
Inside the panel you should see three middle lugs if it is three phase instead of two.. A, B, C phases usually taped off Black, Red, Blue. Then you'll have another wire with white to your neutral lug which is bonded to ground.
If you only have two wires (not counting your neutral) then you're single phase.
