50 amp to 30amp

Is it safe to run 50 amp service through a 30 amp converter?

A quick internet search shows that it should be okay to do that with the right adapter.

The level of amps everything draws is depending on what you turn on, not the breaker markings. A microwave or AC may need 15+ amps but the converter/charger may only need 6 amps. If you turn on more the 30 amps with of stuff, it trips a breaker.

Everything in your RV is run on 120 volts. That's what your looking for.

Although a 50 amp outlet can supply 120 and 240 volts, a proper store bought, 50 amp to 30 amp adaptor will not allow that.

If the adaptor is made by a buddy, all bets are off. Too many use the wrong peices and figure out a way to send that 240 volts into your RV.

I assume you mean a 50a RV on 30a Service, using a 50a/30a dogbone ADAPTER= YES, BUT... 30a x120v= 3500 watts vs 50a x 2-circuits x120vacx50a= 12,000-watts

Its not 2 circuits its ONE 240 volt circuit, split at the breaker box in the RV.

There is rampant confusion on every forum regarding 50 amp 240v RV

Twinboat has a lot of patience

I BEG to disagree. Find me any 240vac devices used in a RV? Even my search for RV clothes dryers for BIG Class-A ONLY found 120vac appliances... IN the USA... NOW EU maybe different? Further, the 50a/30a dog-bone CONNECTS the TWO circuits to ONE circuit in the dog-bone... and that is what makes it work... 30a x120vac x1-circuit feeding BOTH circuits of the 50a RV.

There are several American and Canadian Motor Coach manufacturers that can supply (as an option) their coaches with 240v appliances... Country Coach, Foretravel, Newell,and the Prevost converters come to mind..

Ask Mr. D , a frequent poster on this site. He has a 240 volt clothes dryer in his MH.
Just because you don't use 240 volts in your, or any 50 amp RV, doesn't mean its not there and avalable.

Read your power cord plug, its marked 120/240 volts.

Using the dogbone adaptor limits you to 120 volts only. What's that have to do with it ?
