RV ELECTRICAL PLUG at home?

However a 30A RV receptacle MUST be wired to provide ONLY 120VAC ... whereas 30A dryer or electric stove, (or welder), receptacles are usually wired to provide 240VAC.

Mel, specify 4 wire outlets, as there are 50 amp 3 wire outlets, but of course the plug won't fit.

Just to add to what Mel stated. It is the same but it is the newer 4 wire setup. This is two 120volt hot legs out of phase, a neutral and a ground.
Many older dryer and welder plugs use a 3 wire that has the 2 hots and only a ground. The neutral is missing. Most codes now require the 4 wire plugs.

We had 50 amps installed at our home and our daughters farm. Each time I printed this off and gave to the electrician.

Not a hard job. All #6 wire now includes a ground wire in addition to neutral which need to be paired at the pedestal in older homes that did not use #6 wire with a ground. After pairing at the pedestal I connected to a 8 ft. grounding rod a few feet away. Having 50 amps for the coach has been the best addition I've made. Coach stays plugged up 100% of the time with the fridg. always on.

Many have done it.. I did a 30 myself (Wires existed)

What do you need to be aware of... If you do it yourself proper electrical procedures and installation requirements.

IF you hire it done by a professional: The proper weather protection is about all.. When you hand a RV 50 amp outlet to a professional electrician the odds are in the 'nines' (meaning 99.9999999~% He will do it right (the nines go on a while) and since you are contemplating a 50 amp outlet that's it.

With 30 amps it's a bit more complex and if forum posts are any indication about 50/50 on doing it right. Which is why *I* did mine. I know it was done right.. I'm paranoid (Diagnosed as such in fact).

OK. Here is an electrical question that I just don't know the answer to. Can you run two air cons off 30 A? By the draw I am figuring, there is enough amperage to do it. As long as very little else is on. But I am guessing there is more to it?

Depending on the size of your Air Conditioners, they will draw about 14amps each with a 20+ amp surge when the compressor starts.

With that said, many people have done it but with two running (28amp total) your are on the edge of tripping a 30amp breaker.

And for those touting the 240 volt warning, let's say this correctly.

A standard house 30amp outlet or dryer/welder 30amp outlet is wired for 240 volts. A RV 30amp outlet is wired for 120 volts. Most electricians don't understand the difference, therefore to potential problem.

A 50amp RV outlet is actually wired with 2 50amp 120 volt circuits and 240 volts across the two hot leads. While most RVs today do not use the 240 volt capability, there are a few high-end rigs with 240 volt appliances (dryer and cook tops). There is only one type 50amp outlet scheme, therefore an electrician will not have a problem.

This might help you determine what you can do with True 50amp, Fake 50amp & 30amp:

The quick answer is no. If your running 2 15000 ac units, they'll pull about 12-14 amps running but could pull 15-17 amps at start-up. Your breaker will trip. On my previous 5th wheel that had a 30 amp panel, I added a second ac but wired it separately to the pedestal's 120v outlet with an inline fuse..

I have had 50 amp plugs in my previous home and now at my current and they work perfectly... Just had an electrician run a line from a breaker box to an outside 50 amp plug-in box for just my coach.. (Also had and extra 110 put there as well)...

Currently plugged into it now and it works perfectly....

[wa8yxm]

Bucky, I have run both A/C's 0n 30 amp twice..there are several considerations that must be met.

The condenser coils must be CLEAN, and I mean CLEAN
The outside (and inside) Temps can not be too high, 100+ you likely won't succed The coach batteries must be FULLY charged

No electric water heater, No electric fridge, No electric____ anything.

Just the two A/Cs and your convrter, nothing else running

Park power must also be good (115 minimum) and even then there is no guarantee.

Installed a 50 amp cheap since the breaker panel was on the other side of the wall I mounted it on. I installed 30 in the rv's carport since the power was not so close and I only need it to keep batteries charge and fridge running.

We put in a 50 amp service for the rv 7 years ago and it has been worth every penny it cost.
