Same thing



No, it's not. It's one phase.



Hi,

It's called bi-phase. aka Edison circuit.



Wrong. It's called "split-phase". ...because that's *exactly* what

it is. Two-phase is something entirely different (and quite rare).

180 degrees out of phase and opposite are the same thing.
Look at it on an oscilloscope. What the exact method of
generating it is doesn't matter. If you have 3 wires entering
a box, the relationship between them is what it is, regardless
of how it's generated or what you call it.
