50amp to 30amp

[Scott91370]

We're looking at a site but they only list 50amp service. Well our little 19h has 30. I've read about using a dogbone which drops one leg to bring amperage/voltage down.
Anybody here have experience with these?
Don't most places have 30a in the same box if they offer 50a?

Thanks!!

Yes you can use a dog bone adapter. It doesn't do anything as to dropping amperage down, it's not necessary. Your RV has a 30 amp breaker which will not allow you to pull more power than that.

IF you don't have an EMS (Electrical Management System) you may want to look into one. It will protect your RV from over/under voltage, surges, open neutral, etc. Progressive Industries makes one of the best.

As to your question regarding 30 amp receptacles, many campgrounds do have 50, 30 and 20 at the post, but, many just put in 50 amp, knowing if you only need a 30 you can use an adapter.

Enjoy your Stay.

I carry a dog bone adaptor and have used it twice to plug into a 50 amp outlet. Once when the 30 amp outlet was so worn out that it would not hold the weight of my EMS and once when the 30 amp was mounted upside down and my EMS would not connect without the dog bone. No problems at all and it saved two outings because those parks had no other open electric sites.

And if all they have outlet wise is 50 amp they normally have "lender" adapters.

I would purchase one, they are inexpensive, just to be prepared. You never know what you will encounter.

I always plug my 30amp TT into the 50amp outlet due to so many 30amp outlets being worn out in most campgrounds.

I have a dog bone and it may come in handy at more than this 1 camp ground. I used mine once here there was no 30 amp & two other times because the 30 amp outlet was so worn that the connection kept cutting on and off but the 50 seems to always be working fine because of less use.

[RoyBraddy]

Most camp grounds I have gone to with Electric Pedestals have receptacles for all three 120VAC Service Connections being 20A - 30A and 50A... Each of these will have their separate circuit breaker control at the pedestal.


Having the RV50A to 30A long dog bone adapter with me I can observe the pedestal receptacles like shown here on this GOOGLE Photo where perhaps the 30A receptacle is very well worn out and showing arcing marks etc... I will use the 50A adapter and connect up my 30A Trailer to the 50A receptacle with no issues.

Since my trailer 120VAC Power Distribution Panel has it's own 30A MAIN Circuit breaker this is all of the power I will be using even though 50A is available to use.

Always neat to have the adapters with you just in case you may need one. Will save some headaches...

I got my RV 50A(M) to 30A(F) long DOGBONE adapter from WALMART...

As mentioned, should be just fine, plan for the worse, pick up the adapter dogbone (RV 50A(M) to 30A(F)) and you'll be good shape.

Lots of great help. Thank you!
I did price them and figured I would get one if enough people said they use/like them. I guess for the $20 it is well worth it.

Thanks again and Happy Camping!!

I guess this brings up another questions. Since I don't currently have an EMS and the couple I have looked at are either 50 or 30 amp, not dual, which way would be better? Meaning, if only 50amp is available and I buy a 50 I can't use it with the 30 amp service, right? Or I guess I could buy an adapter that goes from 30 to 50 then the dog bone to go back to 30, right?

I would match the EMS to the rating of your camper - in your case the 30amp model. If only 50amp is available then you'll connect 50/30 dog bone to EMS, EMS to camper. Otherwise it's just Pedestal to EMS, EMS to camper.

Thank you to everyone for the input.

I purchased a 30A Progressive Industries EMS. I did compare it to a couple of others and for the price and warranty it did seem to be the right way to go. I bought a dog bone that is about 12" long but think I am going to swap it out for just the adapter because the extra length appears that it will make the EMS lay on the ground. Any recommendations for locking it to the post?

We also happened upon a great little stand alone ice maker. Makes about 26lbs per day - way better than trying to keep a cooler full of clean ice that always seems to get stuff put in it and that stuff always has dirt on it.

Now I just need the weather to get out of the 20-30 range so I can go have some relaxing fun!!!

I have had one for about 3-4 years. I could have used it twice before I had one. And I have used it twice since I go it. The last time I used it, the 30 amp outlet had a bad ground.

Second time I could have used it, the outlet was in poor condition, had to fiddle with the outlet for a an hour before I got power to the TT. That was when I decided to buy the dogbone.

I have one similar to what Norty posted. I do not use it often, but it is nice to have when you need it.

they make a small "box" like device that locks and doesn't allow the RV plug to be detached from the portable EMS. Works well to keep honest people honest. Most pedestals you can put a small lock on them, not allowing the EMS to be removed also.

I just put in a hard wired EMS mainly because working at campgrounds I like to keep tabs on the voltage when im "home".

[JFlightRisk]

We have on of these Locking & Lockout Devices | Locks-Cables & Chains | Master Lock® Python™ Adjustable Locking Cable | B774511 - GlobalIndustrial.com to go through the metal tab on the EMS, and around the pedestal. Didn't buy from here, just using the description. I think we got it at Wallyworld.
