Newbie! 30 amp to 20 amp converter

Some people should not be giving electrical advice; they don't know what they're talking about. There definitely is 240V available in a 50A RV; it's just not generally used.

So are you saying, I can plug in a 220 volt appliance into a standard 50 amp outlet at a campground and get 220 volts, yet take a "normal" 50 amp plug for an RV and plug into the same outlet and get 50 amp / 110 volt?

A couple of corrections ...

Nominal unloaded source voltage here in N America these days is specified as 240 vac @ 60 Hz, not 220 vac, and 120 vac @ 60 Hz, not 110 vac.

Secondly, of course 240 vac is available from a standard 50 amp RV campsite power source, used primarily in very large rigs that may have an electric clothes dryer - no different than in one's house. However, not many trailers have a dryer nor need 240 vac so the two legs of a standard 50 amp RV source are wired into the trailer as two 120 vac legs, one leg powering some circuits, the other leg powering the remaining circuits. Why this should be so confusing to so many is the real mystery. :?

To the OP ...

Your trailer is wired with 30 amp main service which is 120 vac, not 240 vac. If you want to plug it into 15 amp or 20 amp 120 vac service all you need is a 15 amp Male > 30 amp Female dogbone adapter. It doesn't convert anything but the pin configuration, allowing you to plug your trailer's 30 amp male plug into a 15 amp or 20 amp receptacle.
