I've never seen this EMS (energy management system) on a 30 amp coach. It is designed for a 50 amp service and automatically detects whether plugged into a 50 or 30 amp service. It cannot automatically determine the difference between whether you are plugged into a 30 or 20 amp service and you would have to manually select 20 amp if connected to a 20 amp service. It is designed to turn off certain equipment and stagger start the air conditioner compressors when on 30 or 20 amp service. Can't imagine why someone would replace a 50 amp shore cord with a 30 amp cord, except for easier handling of the 30 amp cord.
Look at your 120 volt ac breaker panel and see if the main breaker is a 30 amp single handle breaker or a 50 amp 2 handle breaker. I'm guessing it will be a 50 amp 2 pole breaker. Also, If the generator is 5500 watts, the coach is supposed to have a 50 amp cord.
I hope this helps clear things up for you. Also, you can find the wiring diagrams for your coach at the Winnebago website.
that model does have an EMS and a 30-amp main breaker. the genny on our 35U was 4000-watts. a 50-amp version of the Suncruiser and Adventurer was offered and I wish we would have ordered that one. the cost of that upgrade was miniscule compared to the overall cost of the MH.
