Electrical connection

I just found a 125/250 50 amp plugin next to the breaker box. What converter would I need to make it a 110/30 amp?

Here's a pic of the plug inClick image for larger version

You need 30amp?
Have never seen a box that had a 50 amp that also didn't have a 30 amp

That's a dryer/welder type plug, 220 volt. He wants to know how to change to 30 amp.

You may be able to split to a 50 amp then an adapter to 30 amp. Get an electrician.

If that is a properly wired 125/250V 30A receptacle there is no way to adapt it to a 30 A 120V RV plug. It will have two hots and a neutral with no ground. You would need to remove the 2-pole breaker supplying it and replace with a 1-pole 30 amp and connect the wire that was on the 2nd pole of the removed breaker to the neutral bar. You could then replace the receptacle with a 30A Rv receptacle. Also need to make sure the ground is correctly connected at the breaker panel which would be to the neutral bar if the panel also contains the main breaker or to a separate ground bar if it is a sub-panel. I would be suspicious of that receptacle and wiring as there is no logical reason for that particular configuration to be there. That type receptacle was typically only used for a clothes dryer when the code allowed the neutral and ground of the dryer to be connected together.

Sorry, I didn't see that it was 50A. Same basic idea as in my previous post but the 2-pole breaker will be a 50 A. That receptacle configuration was for a range with the neutral and ground tied together. I've seen those incorrectly used as welder receptacles.

Ok, so it looks like an electrician will be able to make it work semi painlessly? I wouldn't think it would take a ton of work but I know nothing of electricity. I was surprised to find it and wonder what it was used for. Thanks all!

It's a really old house (1960) and some of the electrical was upgraded when we bought and still needs some work.

Easy to do but you would need basic electrical knowledge. Just replace the two pole 50a breaker with a single 30a then a few wire changes and a new outlet. Probably an hour to do it if you don't run into any issues.

wy husker fan's replay spells it out. easy but it has to be done right. key thing is no wires have to be run. but get it done right as there have been several posts about people damaging their rv by plugging into a miswired 30 amp receptacle. make double and triple sure the electrician wires it as a 110 volt 30 amp rv receptacle (hot, neutral, ground) as opposed to a 220 volt 30 amp dryer receptacle (hot 1, hot2, ground).

I'll wire in a ceiling fan or light but when it comes to heavy voltage or breaker box changes, I'll phone a friend to do those. Electricity scares the crap out of me!

Yes, and electrician can easily make the wiring changes, as he just need to make some changes in your house's electrical panel as WY Husker Fan stated. Shouldn't have to run any new wires, and the ones in place will be overkill.

Make sure to print this PDF out and hand to electrician so as to make sure there are no misunderstandings:
