I did mine just a little different to give me more choices. I took it into the basement and put a 30amp breaker box on the wall. I then went out the outer wall next to the convenience center and put a 30amp connection there so it's weather proof. That way I can use a 30amp cord either with or without a 20amp dog bone and also use a surge protector. That way I can use the 30amp plug in a 50amp site or a 20amp plug in the 30amp site.
