Good grief. It's not an issue of software modeling. It's an issue of
what the circuit really is, how it really behaves. From a circuit
standpoint, you don't need to know if it came from a transformer or
if it came from a synthesized electronically generated source from
a battery. The 240/120 service looks like TWO ideal voltage sources,
that are 180 deg out of phase or equivalently, of opposite polarity
sharing a common neutral. There is no other way to model it. That's
all he's doing. That's what everybody does, because that's what it
is, what it behaves like. If you feel otherwise, show us your alternate
model.

It's a transformer. Single phase in yields single phase out.

All you got is a cheap parlor trick using a dual-trace scope.Â* Good grief!
