Vonner, from what you posted in #7, you probably did not do any damage to your unit, but probably overloaded your generator 30 amp receptacle breaker as it was trying to feed all the load in the trailer on one leg of the 125/230 volt supply. With the new adapter you should have two circuits feeding your 50 amp RV plug with about 23.1 amps per leg. You still have to manage your load in the trailer not to exceed the generator breaker rating..... What is the rating of the generator breaker feeding the 30 amp receptacle?
