See if this diagram helps to understand:

Good diagram. So primary is leg to ground, and secondary center tap is forced to ground. Makes sense.



And note what else it says. It has one hot leg labled "Phase A", the other
"Phase B". That means there are two phases present. Next, look at the
note: "The phase of hot leg 2 (Phase B) is in the opposite direction,
ie 180 degrees apart from the phase of hot leg 1 (Phase A)."

Perhaps you can explain it now to krw that this document clearly
shows two phases present and that they are 180 deg out of phase
with each other. It's precisely in agreement with what I've been
saying for two days now.
