If you are in North America, depending on what kind of power is needed for other businesses nearby, their '3-phase' may not exactly true 3-phase but rather 3-phase created by using a 'wild leg' as referenced to Neutral. Voltage across all 3 or any 2 lines is the same. Voltage from either L1 or L2 referenced to Neutral is balanced to 1/2 the L1-L2 voltage. For 208 VAC that is 110V for L1 or L2 to Neutral. Voltage on the 3rd or Wild leg referenced to Neutral is much because it is is NOT reference to Neutral. The 3rd leg is supplied only to places needing 3-phase to run motors, refrigeration, and other application requiring it that are powered by all three phases. If that is the case the utility is already supplying single phase power over very heavy lines feeding several other locations nearby.

Are you just saying that the TDU should be able to balance things on their side easier than I make it seem?

Also, you're not referring to "high-leg delta" voltage are you? I am considering requesting 240 3 phase in the delta config:

This setup is as true of 3 phase as 120/208 right?
