jackrae:
You talk about 2-phase. Do you mean 2 phases plus a neutral from a 3-phase system or do you mean 220 supply rather than 110 as the USA uses. If the latter then I'm sorry to advise that it's still single phase even if running at 220.
1 phase - 220V
2 phases - 380V. It's a system specific to Dutch (I hope I don't mix countries 
) network, not sure how they manage it.
