I asked about 50 or 30 amp service because you CANNOT add excess amp draw to a 30 amp box. 30 amp RV boxes are designed for the 30 amp load in the RV and are designed to split the loads to total 30 amp. If you are trying to run an extra 20 amp circuit and appliance you will overload and trip the Main 30 amp breaker in the Breaker box or the CG pedestal pole breaker. Not really dangerous as the breakers will do their job but just an annoyance. Doug
You still have the option of "power management" to not overload.
There is also the confusion where USA posters often say "20a" when talking about 15a. The key is whether the "20a" really has 12 wire instead of 14 wire to it.
Not sure the OP has a clue about all that.
