Yes, 10-3 is fine, and 208 is absolutly the most common 3 phase voltage.?
First, is possible there is 480/277 (those are two voltages that are part of the same system, like 120/208; if you have one you tend to have the other) in your building, but in order to get down to 120 volts it would run to a transformer and get dropped to either 120/208?3-phase?or, more rarely, 120/240 3-phase.?
Your saw will run fine on 208 or 240 3 phase most likely.?
