Technically you mean opposite phase, not three-phase.

Three-phase power is rarely (never?) seen in residential settings. It's a commercial/industrial service.

Edit: s/opposite polarity/opposite phase/

In Europe (Portugal at least) three-phase is the norm in residential installs. I assume it's because that way the power company gets to gouge you on the power fee. You need to sign up for more total power as your consumption is never perfectly balanced between the three phases.

In the US maybe, in Europe (The Netherlands at least) three phase power to the home is the norm. Split phase is weird to me...

Yep, I was speaking about the US. Didn't know that about Europe. In the US three-phase power is only seen in commercial or industrial installations. I know a machinist who has a lathe in his home workshop that requires three-phase power. He can't get it from the utility so he makes his own by using a single-phase electric motor to drive a three-phase motor as a generator.
