Tommy, you are talking about "Single Phase " power where there are two hots
and a neutral, then there is 240 between the two hots and 120 to from each
hot to neutral ie: three wires. But on many 240 volt electronic items there
are only 2 wires. A hot and neutral with 240 between them. Correct me if I
am wrong, or did I miss your point ?
