Electrical Issue

I had a man in a class C RV parked next to me at campground and 30 amp plug did not work and he asked me what would happen if he used an adapter and plug his RV in to 50 amp.
Not being an electrician, I believe that it is not a good thing, but I couldn't tell him what would happen if he did plug it in.
Can anyone give me the answer? Thanks

nothing would happen, he would just draw up to the amps of his rv and nothing more.

Works fine. Adapter plugs are available at Walmart, Camping World, etc.

People do that all the time, In fact due to the tendency for the 30 amp outlets to be wore out,, Some do it ALL the time.

Think of it like this.. A 60 watt lamp in your house draws about 1/2 amp, but the outlet you plug it into is a 15 amp outlet.. Yet nothing bad happens when you plug in that 1/2 amp lamp

There is actually a slight benefit to doing that if he actually draws nearly 30A. The 30A outlet is maxxed out at 30 and actually deisgned for a sustained power draw of 24A (80% x 30A). It will get warm and can even melt the RV plug is it operates at 25A-30A for more than 30 minutes or so. The 50A outlet is still loafing along comfortably in its mid range when supplying the full 30A, and is also less likely to suffer from voltage drops if others in the park are making heavy power demands at the same time.

I have been in one RV park where the 30 amp receptacle voltage dropped too low when everyone had their AC running. Using the 50/30 amp adapter gave me a higher voltage. The park was an older one that started out with all 30 amp outlets and instead of connecting the 30 amp breaker to one leg of the new 50 amp line they kept the original 30 amp wiring. By using the adapter I took advantage of the larger 50 amp line with less drop.

On a 30 amp system your wires are
Ground neutral and 120 volts.
On 50 amps system you have ground neutral 120 volts and 120 volts. If you use a 50 amp adapter you are still only getting ground neutral and 120 volts. Because the adapter eliminates one of the 120 volt lines.

Yes, in essence, with 50 Amp you get two "legs" of 50 Amp each and since nothing on your RV using 240/220volts, you essentially have 100 amps available.

But using a 30amp adapter you are limiting yourself to one leg of 30 amps, thus the adapter takes you from 100 amps to 30 amps.

The 50 to 30 amp adapter only uses one "hot" lead from the 50 amp connector. Your 30 amp panel would not notice a difference..


A good explanation of RV electrical systems is here: http://www.dmbruss.com/zFullTimeLife...stribution.htm

Only concern is you have a 30 amp wire protected by a 50 amp breaker which could be code violation except that is a plug in cord.

Just be sure all is well with cord and panel as the protection from supply breaker is different.
