Let's say I have a breaker rated 120/240. If I wanted to use that to feed a 240v single phase load out of a 120/240 3 phase panel would it be allowed to go on phase A and B (high leg). OK now on a slash rated breaker if I recall correctly the NOMINAL voltage to ground can not exceed the lower of the two values (120). IMO the 208 to ground on the high leg is not a nominal voltage. So I think this would be fine. Am I understanding this correctly? I believe code article was 240.87
