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
30A boxes are already overloaded. Try running a/c, water heater, refrigerator, lights and one good plug load at the same time.
A bigger issue to note about adding circuits is the NEC only allows five branch circuits from a 30A panel. This note only applies if you actually care what the NEC says.
