Not really true. All circuit breakers are made to protect the wire coming from them (down stream). How is a 50 amp circuit breaker protecting the 30 amp (rated) dog bone plugs, shore line, coach receptacle, connection wire and ATS from over current damage?Look at the drawing in post #23. Your dog bone is only linked to one leg of the 50A outlet and that is exactly what the 30A outlet does - connect one leg of the power grid’s 240V service. You won’t hut anything and your RV won’t know the difference.
You are relying on a down stream circuit breaker which is against every electrical code. We all do it, but I know the risk and willing to take it because of the convenience of carrying 50 ft of 10 awg extension cord instead of a 8 awg 4 wire extension cord for those rare occasions.
