50 AMP and plugging in at home

Although new to this, I strongly suspect that a coach that has 50 AMP service may not be able to run A/C in the Texas heat on an standard outdoor extension cord plugged into an exterior house outlet. I'll make the assumption the generator can handle but would prefer to run off the electricity from the house when here.

Do I need to install a new breaker at home that has the capacity to power the coach including the A/C units on a 39' coach?

Yes very standard NEMA 14-50 connector, two pole 50 amp breaker, and 6/3 wire to connect. Slam dunk for any licensed electrician. Only thing that might run up the cost is pulling the wire depending on conditions.

No,

It needs to be #6 wire, not #10.

I installed a 30A outlet in my garage and have no trouble running one AC unit. With care (not starting them simultaneously) I can run two. Or I can run one and the fridge.

Getting a full electrical service at home is a really nice thing to do/have done. I love being able to use my RV to the fullest even in the driveway (hell, even the "doghouse" isn't so bad when DW sends me there :))

Next step is to be able to dump tanks at home. This was a real game changer for me. No more waiting in line heading out of the campground on Sunday. No more making the kids "hold it" until we get home.


So is this a 'hostile integration' into the plumbing that goes out to the street assuming city sewage and not septic?

Very appealing to me too.

This is the correct thing to do. You wonโ€™t regret it.

Whoa Kimo Sabbe! It's a bit more complicated than simply replacing a breaker and receptacle. That is unless your home fire insurance is paid in full, you no longer like your house, and the insurance company won't find you at fault for frying all the wiring inside your box. Generally, 20amp service, (Tee shaped receptacle) uses 12 ga wire, 15amp service (Double I shaped receptacle) uses 14 ga wire. 50amp service uses a minimum of 10ga wire, depending on the length of the run. Simply changing out the breaker and receptacle will allow you to power up you A/C units for a bit as your breaker will not trip. However, your house wiring will then become a substitute for your breaker. Once the wiring gets too hot, it will melt and burn through if you're lucky. If you're not so lucky, it'll simply start a fire and burn your house down. Hire a licensed electrician....Dennis


LOVE THIS! I learned a long time ago what I am capable of, what I am not capable of and what is just plain stupid to attempt and this falls under the later.

Anyone who was in the Navy remembers, "The Deadly Shipmate" and I prefer not to mess with electricity at sea or on land unless it's a simple light switch or house outlet.

We have 50amp in our FW and plug in to our 30amp in our house using a 50 - 30 pigtail. We can run only one of our AC's, but one is better than none when needed.

Forget a 20A plug. You might get by on 30A. You'll have no restrictions with 50A.

50A is a 120/240V circuit and RVers use it as 2 50A 120V circuits since it's a very rare RV that 240V appliances. The cons are installation cost and heaver cords and the pros are no RV power limitations.

What is the length of your cords? At my sons house I run 105' of 50A without significant voltage drop.

I can run one 15k A/C on a 20 amp outlet as long as I run nothing else. But I would not do it on a long extension cord. On 30 amp you can easily run a 15k A/C plus a few other lower current things. On 50 amp you can run all you want.

Make sure whoever installs the new outlet understand how it should be done.
