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.



"phase" has a meaning. There's still 2 of them. "split-phase" sounds

right too.



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





I think I've heard about that. Are the phases 90 degrees apart?



Yes. From it, any variation or number of phases can be easily

generated (efficiently). It's just a little trig and a transformer.



The fact that there is this different 2 phase system doesn't prevent the

usual one from being 2 phase. That's be like saying you don't have 2

colors of holiday lights if they're just red and green.



Words mean things. The proper term for the Edison connection is

"split-phase". It *is* a single phase that is split by a

center-tapped transformer (center grounded).

But that isn't what you objected to. You objected to someone
saying the two hot legs at the dryer are out of phase by 180 deg
with each other. That is true as can be seen on a scope.
And when you split something, can you cite
an example where after splitting, you still have just one?
