What happens when 50 amp is not available

I have the 2019 Pinnicle. It requires 50amp electric hook up. My Question is if the camp ground only has 30amp what will or will not work ? I do have the 50 to 30 converter cord.

If you have the proper adapter, all power will work but you will only have 30a available . You will likely be able to run only one ac at a time. When we have this situation, we only run ac at a time, operate the water heater on gas to conserve current load and conserve current use by not operating high current devices like coffee maker or hair dryers at the same time.

With 50a service, you have 2-120v legs and each is 50amps so the 30a service limits you to about 1/3 less current capacity.

Get yourself a good high quality 30A to 50A adaptor and you will be good. You just have to watch your loads as you will have a lot less current available. 30A total vs 50A per leg on 50A.

To save on current requirements we use a stainless steel carafe drip coffee maker. It heats water drips thru and done
We can and have run 15k a/c, electric hot water, made coffee, run tv and lights, radio bathroom fan ceiling fan microwave all at once as needed Our lights are led ones from jayco original. With the ac running it draws 13-14 amps alone. Electric Hot water draws 10 amps. I have a progressive dynamics unit it shows the amps on each leg.

Yep as Norty and Earl said it will work. Just watch what you have on at one time

We even attended many Rallies in Fairgrounds where we only had 20 AMP available & we could still run our air. All we needed to do is put the a/c on fan until you were done with the microwave or coffee pot etc and we kept the water heater on gas.

I’ve read several times (on JOF) that a dog-bone adapter (30-50A) is far superior to the “block” style. They tend to get hot and melt. We’ve had to run 30A a couple of times and 1 AC at a time is the order of the day.

Block adapter will melt. Get a dog bone type. Gives the heat a larger surface to dissipate from

Also, run the fridge on propane. My 4 door unit pulls 3-5 amps I think. When I am using my little inverter generator it runs at full speed if the fridge is on AC. If I set the fridge to propane the generator will drop down to idle mode. At that point I only have the TV and lights on.

I have used this twin 30Amp to 50Amp adapter when there are two 30Amp circuits available (like our state parks, and my Dad’s house).

I used it for about 5 days running both A/Cs.

Your 50amp service is two120 volt 50 amp lines, giving you 12,000 watts of available power. The 30 amp service is one 120 volt line, giving you 3600 watts of available power. As others have said, one AC at a time, water on propane, MW off when AC is on and you should be good. Also hair dryers, toasters etc may cause over loading. use with caution, or turn AC off when using them


Good Luck and Semper Fi....another Wagner to boot !

Connected to two 30 amp circuits, the adapter provides the two 120 volt 30 amp lines to the 50 amp connector, and it will run both a/c units. You do still need to be careful and not run everything! You can connect the adapter to the separate circuits one at a time and test the 50amp connector to see which circuit feeds which 50amp prong.

Thbanks everyone. I do have the 50 to 30amp dog bone. This site is great for information. Now I understand it and what I have to do.

For reference, I can run one AC, my residential fridge, and everything else inside with my 3400 generator. I believe that’s not quite 30amp. Only time I’ve over taxed that was all those things running and I added a vacuum to the mix. So, 30amp is definitely fine. Unless it’s so hot you need 2 AC units running.

I use an adapter which a 50 to two 30amp. Each leg has 30 amp and that's usually enough for fridge, both airs, microwave and electric water heater.

A 50 amp line gives you 12,000 potential wattage (2 120 volt lines) and the 20 amp will give you 2400 watts of power. Using the above adapter, you plug your 50 amp RV line into it and then plug it into the 30 amp outlet and the 20 amp outlet. This will give you 6000 watts of potential power at 120 volts. OR, 1/2 of your normal 50 amp plug. You should be able to use both AC on the above adapter, but, will have to watch other appliances since you only have half your normal power available.



I have not seen two 30 amp 120 volt outlets on a single pedestal..



All 30 amp outlets on the pedestal are a single 120 volt line, or, 3600 watts.



Good Luck and Happy camping.

I have never seen such an adapter, nor have I seen a pedestal that offers two 30 amp outlets. Can you post a picture of what your using ?



Thanks
