30amp to 50amp dog bone

[ckwizard777]

Is it safe to use one of these to plug my 50amp trailer in at home.
I have a 30amp plug at home and mainly just want to keep the batteries charged.
Thanks

We are presently running our 3400RL on the 50-30 adapter at a campground and keep plugged in to 20 amp outlet while in storage via a 30-20 amp adapter. There is still enough power to operate some equipment. You will need a #10 wire extention cord if you want to run the ac though.

Do use a dogbone adapter, not the 'hockey puck' style. My hockey puck let out the magic smoke when I ran the amps for an air conditioner through it.

Thanks for all the replies.
I just wanted to make sure I didnt fry something in our new to us trailer.

The battery (ies) will stay charged on a 15Amp household outlet, with the right stack of adapters. That will also run the fridge and lights (at the same time).

I have a 30Amp in the yard and when we were upgrading the main panel for the house I had the electrician leave a spare 50Amp double breaker which I later wired for a box from Lowes to serve the driveway when we are loading.

With the right adapter, we also run the MIG welder off the 50Amp box.

according to my manuals on my new to me 5ver it really depends on amp draw, the converter trickle charges the bat so I would assume the amp draw for charging is under 15 ?

For years I have had a 30 amp receptacle both in my shop and my back yard and I use a dog bone and I have never had a problem. I used to park my trailer in my shop. Over the years you make many good RV friends, the only way you can get them to come visit you is if you have full hook ups thus the 30 amp service out back. I have since built an RV barn out back and now park my trailer out there. I have considered upgrading to 50 amp service but have decided that I really don't need it. Like others have said it will work just fine as long as you only use one A/C.

KEN,I have 30A to 50A set up at the house. Works great for me.

we run into a 30A plug at home. no problems. just won't be able to run 2nd ac

ckwizard777, I used the 50-30amp adapter when we traded up to our Montana 3400RL before I was able to upgrade to 50amp hookup and experienced no issues. As you probably already know, you will not be able to run 2 air units but everything else will operate as normal. You may also be interested in the Montana Owners Club forum. Great people with a wealth of information. Enjoy your new rig and safe travels. Tim

Works fine and you won't know the difference except for the 30A limit.

[Dennis_M_M]

No sweat, we spent the last 5 winters on 30 amp with the doggone connector. Everything works fine, even the single AC.

Thanks guys,
Yeh I just sold the TT and picked up a Montana 3400 and have not had a chance to rewire the box for 50amp yet but I do have the adapter hence the question.

Last fall I had a 30 amp 110 volt post added to my back yard where I park the trailer. This year we bought a new fiver that has 50 amp...wouldn't you know it. I use the adapter and it is fine.

As long as the 30 amp is 110 volt not 220 volt.
