Tony, this is my first post on this subject, put it is hard not to jump in
when you respond so negatively to a post you clearly didn't thoroughly
read. Matt was comparing "split phase" and "two" phase with 180 degree
phase separation in which he correctly states that the two phases are 180-
degrees apart. His statement about them being identical is also entirely
correct.

I believe he does demonstrate he knows the difference between single and
three phase.

Now, of course, three phase power can be either wye or delta connected and
there is a difference between these two kinds of three phase power. I'm
sure you can explain the difference to us in simple terms and which kind is
used for general power distribution and why. When is the other kind used?

Yes, there is a difference, but it is pretty small ... one more
conductor. :-)
