Giedo, In America most residential areas and fringe (read rural) areas only have single phase. Back in the 70s when I worked as an electrician, although pretty much everywhere I worked had 120/240v available many old houses had only 120v 1 phase power. I made quite a bit of money changing out old 120v main fuse boxes to 120/240 breaker boxes. I wouldn't be surprised if there aren't still a lot of 120v services in the more rural parts of America.
