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 ? Keith Trumbla O/O B.E.M Electronics Inc.
