Because the 50 amp RV service is actually two legs of 50 amp service, the way the box is wired is to have one leg of the service (primary) be supplied by the 30 amp RV socket and the other leg of service be supplied by the 20 amp Duplex.
It works on panels that are seperately fused for each circuit like this: The 50 amp socket comes off the sub-panel "main" and the 30 and 20 are off each leg of the 50 amp main.
This is not what the Y thread is talking about (I think).
