I am not an electrician, but it's my understanding that a properly wired 30 AMP RV receptacle has 1 hot (L1) a neutral and a ground. It should be 120 v. Plugging in an adapter, it would feed the L1 across the 2 hots on the 50 RV outlet. I don't see how you can measure 235 volts across those lines as the adapter is just splitting the L1 and you don't have an L1 and L2 at differnt phases to provide the 235v... I'm looking for an explanation !
I believe the OP has a 30 amp 240 volt twistlock outlet, not a 30 amp 120 volt TT outlet.
