I think Danny now has a much better idea of how his electrical panel
works, and it's really just that part that matters. If he uses the
technically incorrect but easy to understand notion that power is
delivered by the L1 and L2 power cables that distribute power
throughout his house on red and black wires, and returns back to the
panel on the white wires, and that the L1 and L2 power sources are each
120 VAC relative to the neutral, but 180 degrees out of phase so that
there's 240 VAC between them, then he knows more than most homeowners
and enough not to electrocude himself, and that's what counts.

So I'm confused. Are my 240 volt appliances single phase or two phase?

Look on the manufacturers name plate...you'll likely see that it is
single phase.

L1 to L2 is 240 volt single phase. The center / neutral tap is not
needed for 240 volt service.

The 2 phase claim is bogus.

Beware of trolls.
