SO I have a natural gas dryer that has a 30 amp dedicated breaker. The dryer outlet looks like any old 15-20 amp outlet as I understand that it is soley for running the motor as the heating comes from the natural gas. My question is....can I tap into this outlet and put a 30 amp RV outlet directly behind it on the outside wall to plug my RV into? I don't plan on running water heater or AC while camper is plugged in at home...primarily to charge battery and keep fridges on...OR am I better off tapping into an existing 20 amp and just using an adapter?

Considering your gas dryer also uses 120 volts for the "gas valve" (not referred to as an element) you may need some fine tuning on electrical circuits. The 30 amp outlet for your dryer is 240 consisting of two hot, and one ground wire where as your RV uses one hot, one ground and one neutral wire for 120 volts. It would be better to add one 30 amp 120 volt CB and the proper wire to an RV outlet and much safer it would be. The RV outlet polarity must be wired correct as well.

You can google RV outlet wiring schematics and if you are not sure, well?

A 20 amp circuit is fine for just charging the battery and running the fridge. I keep mine plugged into a 20 amp circuit all year long.

Your 30 amp dryer outlet has two hots and a neutral, and uses the neutral as ground. To utilize it as a 30 amp RV outlet, it needs one hot, the neutral, and a separate ground.

I would just use your 20 amp outlet with an adapter.

Wait, on edit I see that your dryer outlet is a plain 15-20 amp outlet with a 30 amp breaker? That isn't right... What size is the branch wire?

If the dryer is on a single pole, 30 amp, circuit breaker the answer is yes. (Inside the breaker panel the wiring from the plug should be 3 wires - hot, neutral and ground.)

Yes you can. Doubt it meets code. Best to install a covered GFCI outlet for the RV. Use an adapter.

If the outlet is 30 amp to power a dryer it will have 240v available and a NEMA 10-30 or 14-30 connector. This cannot be directly used for the 30 amp RV.

Perhaps you need to check your dryer breaker to see if the one in your panel is 30 double pole, and you have another individual breaker that feeds power to your gas dryer. The gas dryer requires a dedicated circuit, but it is 120 volts and should have a 15 or 20 amp single breaker.

In either case, the answer is no, you should not tap into that circuit.

Something is wrong with this picture.
30A breaker ending in a 15A outlet? If one of the slots is sideways, it is a 20A. Still not right and could be dangerous.
Is that a single or double pole breaker?
Was there once an electric dryer there?
As for now, just plug into a 15 or 20A outlet with a dogbone until you know what’s happening with that dryer outlet.

Yes I agree, the explanation doesn’t make sense. A natural gas dryer will use a 20A circuit. So if it looks like a standard outlet it is more than likely 110V 20A (possibly even 15). However there are some outlets that look like a standard 110 outlet that are actually 220. I think you need to do some more research on what you actually have.

To clarify...it is a double pole 30 amp breaker...and it leads to the outlet in the laundry room and the washer and dryer are both plugged into what appears to be a standard 15-20 amp grounded outlet.
