50A is also single phase ;)
It's split phase Discription
From the wikipedia link:
"This results in two 120 V AC line voltages which are out of phase by 180 degrees with each other." (Sounds like 2 phases to me.)
"Since the two phasors do not define a unique direction of rotation for a revolving magnetic field, a split single-phase is not a two-phase system."
Contradiction? That's because "two-phase system" has a formal definition of 2 phases being 90 degrees apart. Split-phase has 2 phases 180 degrees apart. So while split-phase can't be called two-phase, it's not single phase either. It's a supply that has 2 phases and it's called split-phase.
