220 dryer plug to 30A?

The dryer outlet can be rewired by a qualified electrican, but DO NOT plug a 30 amp OR a 50 amp into a dryer receptacle.

A 50A RV plug is TWO 120V legs limited to 50A each. Folks really should not post in this kind of thread unless you know what you are talking about.

Modern code requires the neutral. So, it depends.

This is easily done. It can be done safely if you can follow directions. And yes, 30 amps will be available to you.

Step #1:
At your mom's house, is the dryer outlet (which is female) a 3-prong or a 4-prong receptacle?

Step #2: I won't go there until you answer step 1.

You know, I read this stuff and I still think this is not something for just anyone to try. Many of you give the false impression that this may be an easy task. It may be for you and innocent to recommend, but many people out there have never tackled anything as complex as well as dangerous as an open electrical panel. All someone has to do is forget one simple step you have recommended such as "SHUT OFF THE MAIN BREAKER TO THE PANEL" before they stick a screwdriver in there and it's all over!
Maybe the adapter plug that plugs into the dryer plug is an idea that can work as the plug in is protected by a breaker.
I personally don't think this is the forum to make these kind of recommendations as we don't know who will actually attempt to do this and what their skill level is.

OMG, again know just enough about electricity to be dangerous. Find a licensed Electrician, pay him to do job. If he like me, he has 690 hours education, 8000 hrs apprentice, 30 hours continuing education and a license. Those are minimum requirements. If some house is wired with 12 awg and then 14 awg, it better be a 15 amp breaker, if not, better call Holmes on homes. If they admit they are not Electrician, disregard the post. Why risk the RV, the in-laws house, shock, fire or anything else?

Seems to me an easy solution may be to get a portable air conditioner for under 300 bucks (no need to be IN a window but does require to be ventilated out one.. seems easy enough) at home depot

7,000 BTU Portable Air Conditioner with Dehumidifier Function (67 Pints/Day) and Remote Control-LP0711WNR at The Home Depot

Specs say: Amperage (amps) : 7.6 A which is low enough to run other things in the RV also... like tv and lights, though it may be wise not to run high amp stuff like convection oven etc at same time....but for when you are not in the unit (for the dogs) and when you are sleeping, why not? I thought I read moms outlet was 20 amp.

And definitely have the high amp rated extension cord not the cheap ones.

Thats what I would do, then I would have that AC handy for future similar scenarios. :-)

Here Here!
If you know what your doing then go ahead. If you don't find out or hire a pro. But don't try to sift through this thread to understand. There is enough misinformation here to make everything worthless. Remember just because someone’s logon reads like he knows doesn't mean he does. If you don't know the credentials personally of the guy you take advice from then the information isn't any good.

I'm not saying any of the posts are good or bad, I'm saying YOU DON'T KNOW. Be carefull and know your sources before you act, and most of all understand what your doing. After it's over is not the time to find out who was right.

A board like this isn't the place to get this kind of advice.

I think if you do a search, all electric dryers require a 30 amp protected circuit. This means the use of a double 30 amp breaker with a tie between the two toggle levers of the breaker. Any current draw in excess of 30 amps, whither it is hot to hot or hot to neutral, will trip the breaker.

NEC requires that all new electric dryer installations be done using a NEMA 14-30 plug/receptical, which is a 4 bladed connection - two hots, a neutral and a ground. The old three bladed plug NEMA 10-30 plug/receptical is no longer acceptable on new installations. It is still allowed in old installations only if a separate ground wire is used.

Now, the NEMA 14-50 plug/receptical used on stoves and RV's is not interchangeable with a NEMA 14-30 plug/receptical -ON PURPOSE - to prevent a 30 amp device from being plugged into a 50 amp service. The ground blade on a NEMA 14-30 plug/receptacle is a "L" shaped blade while the NEMA 14-50 plug/receptical ground is a straight blade.

So, what does this mean? A 50 to 30 amp dogbone will not work. A special adapter would need to be made.

Checkout NEMA connectors in Wikipedia for more information on NEMA plugs/recepticals.

Even a licensed electrician can cause problems. We had one here at work, the finally started calling him "Sparky" and he lived up to it. I was present at one such "event". He survived but he did get "bit" good.

Done with this thread! Can't be part of advice I don't believe in.

Electricity shouldn't be messed with! Not something for the un-trained!

The OP wanted to plug 30 A 120 Volt RV plug into 30 A dryer outlet by making adapter.

A 30 A dryer outlet will supply ....30 amps.

He is not connecting 50 A 220 RV volt plug. He is not changing the outlet or doing anything hot. He is not changing his mom's wiring.

How did this get so far off topic?
