That's correct and unless you automate it's operation you would have to monitor the voltage to determine when to connect it, an impossible situation. I think you'll find your going to need either a 1.2KVA unit for a 50 amp service or a 0.6KVA for a 30 amp unit. Keep in mind that the autoformer will throw off heat depending on load so try to locate it in a cool place or where there is ventilation, that is if your going to hardwire the unit. Good luck.
