What isn't being mentioned when we discuss two 110 V legs is they have to be out of phase to create 220V service. My understanding is that the 50 Amp service we hook into at RV Resort/Park pedestals, the two 110V 50 amp legs are not out of phase and therefore 220V is never present inside the RV.
Not so. If that was the case, the neutral would carry 100 amps if you were able to use all 50 amps on each hot leg. They must be opposite phase. If done correctly, when the load is the same on each hot leg the neutral carries nothing. The neutral only carries the difference between the hot legs. You can plug into any properly wired 220vac outlet as long as the plug and receptacle match (or you have the properly wired adapters).
It's all done in the RV. Each load is wired across only one hot leg and the neutral so the load will only see 110vac. A load would need to be wired across both hot legs to see 220vac.
Edit: It must have a neutral and ground. Any receptacle with no neutral (like a welder plug) should never be used for a RV.
Dumb question.....what if you ran a separate neutral back to the panel for your adapter?
