I purchased a 30amp to 50amp adapter from Etrailer. I took my multi-meter to the garage yesterday to test the plug. I think it is wired correctly but I wanted to make sure before I plug in my new 100K+ motorhome!
If you are looking at the 50 amp plug, there are 3 vertical holes (one on top and two on the sides) and then one round ground plug. I believe the top hole is the neutral. Going from the top hole to one of the side holes, I get 117 volts. If I go from both the outside holes, I get 235 volts. I believe this is correct but can someone please confirm?
Thanks,

If you can measure 235 volts at your 50 amp adaptor, then the 30 amp plug is wired with two hots. No problem for your 50 amp RV, but if someone plugs a 30 amp RV into that, it's smoke time.
