<strong>Yahoo Message Number: 6252</strong>Question, does a 50 amp autoformer work on 30 amp service? How well? Do you size the autoformer based on the service you use or your coach? I have been told to use the 30 amp since that is where the problems lie. I have been told to use the 50 amp because that is what your coach uses. I need some clarity based on FACTS. <br/>Thanks
