@John H posted:Rich, household 220 volts comes in on two separate legs. The phase problem arises if you have transformers hooked to outlets on different legs. Using a single outlet will not have this problem, because it is only using one leg . You would still have to have all transformers on that one outlet in phase with each other, which is just a simple orientation of the cord plug if needed.
Makes sense John. I can't imagine using more than a 120V-20amp breaker to power my layout, thks !
