50 amp to 110v

Just got a newer fifthwheel and my other trailer was 30 amp and my newer rv is 50 amp i. My question is how would I connect to the trailer so I can just run like slide outs and lights hopefully refrigerator at my house

Get a 50A to 120VAC adapter and just plug it in. Be aware that you are limited by the amperage of the 120V outlet.

If your shore cord plugs into the trailer, there are adapters that plug into the trailer and allow you to run an extension cord. I use one almost daily if I'm just turning on lights and operating a slide.

Use the largest gauge wire you can get in the shortest length cord as it will minimize voltage drop. Sounds like you know you don't want to operate the WH on electric, or the microwave and AC.

If your cord is attached, then you'll need 2 "dog bones", 50-30 and 30-15.

You can purchase a converter plug which will take the unit from a 50 amp plug to a 30amp connector. From there you can take the 30 amp connector down to a 15 amp connector that you can plug into the ordinary plug on the side of your house. This will enable you to move slides lights and maybe operate the fridge depending how large it is and what the draw is but nothing else. I will put a warning on this though it is not recommended to reduce below 30 amp but many have done it. I did it with my class a I previously owned and had no issues doing so for quite a few years. I am not an electrician and I am sure someone with an electrical background can explain why.

I just purchased one from Amazon, its a Camco product, 90 degree 50amp screw on with a male 110volt plug other end to us at the house, runs everything but the big stuff. It does run frig as mine was running off of it.
Camco 55638 12" 15M/50F Power Grip Dogbone with 90 Degree Locking Adapters

I went with a 50a/30a dogbone adapter for those parks with only 30a service and then bought a relatively inexpensive 30a/15a plug adapter, which is what I use at home to keep the trailer "hot" for the converter to keep the batteries charged. Walmart usually carries all that.

One of these days, I'll get my "Sparky" friend/contractor to run a 50a or 30a service for me and the occasional visiting rig.

I run a 50a/30a dogbone, then a 30a/15a dogbone to a 12 guage extension cord that I plug into a normal duplex outlet running to a 20a breaker in my main house panel. Runs everything including the 15k a/c just fine

Your AC compressor needs 14amp to start.If ANYTHING else is on your slowly killing the compressor every time it starts.

Things you should have:

50 to 30 amp dog bone. Plugs into trailer and has a male 30 amp connector on the other end.

30 cable - 25' is good - male 30 amp on one end and female 30 amp on the other. Great for those parks that don't offer 50 amp connections. Saves your back from dragging out that massive 50 amp shore line.

30 amp to 15 amp adapter. Female 30 amp on one side - male 15 amp on the other.

I use the dogbone and the 30 to 15 adapter a lot when we boondock and need to run the generator. Gives us some 110vac for the microwave and Keurig and maybe the hand mixer plus runs the convertor to recharge the batteries.

When we're home, the dog bone and 30 to 15 adapter is the norm so I can run my 100' heavy duty extension cord out to the trailer. We don't use the AC or 110 hot water element so it works real well for us.

I'm going to reiterate a few things that have been said and a couple more important points. RV AC's should not be run off 100 foot heavy duty extension cords. Your average heavy duty from your favorite Home Depot is probably 14 or 16 gauge wire. An actual heavy duty is 10 gauge. Every time you swap dog bones (50 to 30, 30 to 20) there is a drop in power, as is there a drop in power on the extension cord.
Use your extension cord only to charge your batteries and run only battery powered items in your RV. I will give in to a TV or maybe the fridge, nothing else.
Okay, I'm ready for the naysayers.

No naysaying from me.

Let me qualify my statement a little. I said it WILL run everything just fine, however I did not say that I DO run everything at the same time. Usually when I am in my driveway plugged in the way that I am I usually only flip on the A/C and maybe the flat screen TV at the same time. I do not try to run the a/c, tv, micro, fridge, water heater, converter, etc. all at once and agree that my statement sort of looked that way. Sorry for the confusion.

I put a 50A receptacle on the outside of my garage that doubles as a place to plug a generator in to back feed the house when power goes out as it does here a couple times a year. This did require adding a transfer switch as well.

I have had this thing for many years. Takes all the guess work out of questionable extension cords.

I just bought this one. Nice to know the voltage at a glance.

We use this same adapter and it works well for us. I’d like to add that we found a very stout black 12 gauge 50 foot extension cord on Amazon made by Monoprice that is positively reviewed and works for us. A less expensive yellow 24 foot cord purchased from Camping World actually melted at the house AC outlet!
