2 phase lines are 90 degrees apart electrically. 240V house power is single phase and is sometimes called split phase.
hmmm ... I think maybe you meant 120 degrees apart ... and yes if you only look at the difference between line one and line 2 it's single phase which is what most 240V devices see. It's just a point of view. I'm thinking about it from power into the house perpective and your looking at it as power distribute to the device.
I don't think we are disagreeing here, If you don't distribute the neutral, the outlet is single phase ... but what is it if you do distribute the neutral?
Anyway, It would have been nice to have all three phases but I don't think it's distributed on the pole in residential areas. There are a few machines I'd would have consider'ed if it was.
