30 amp service on home

We keep our trailer outside next to the garage, just about 12' from where the electric service panel is inside the garage. We can plug into a 20 amp and run most everything but the AC. I will sometimes sleep out in the trailer with the grandkids when they stay over, they love it, but on summer days it can get hot until well after their bedtime.



Has anyone gotten an electrician to install a 30 amp plug on the outside of their home, and if so, what did it cost?

I run my 15k AC off of my 20 amp on occasion. Typically, I don't have anything else running at the time.

As has been stated if it's a 20amp circuit (20 amp breaker and #12 wire) you should be o.k. on the air con as long as your fridge and hwh are not on electric. A 30 amp service will vary in cost dependent upon the length of run and the area. You said 12' away so you could look up online at Lowes or Home Depot and get a sense for material costs. You need 30 amp breaker to match your panel, a 30a rv receptacle and box,and guessing at 25' of 4 conductor # 10 wire. Then add labor and any permit costs if applicable. Most electricians will offer a free estimate for that type work.

If you hire an electrician to install a 30A receptacle for your trailer, have them use this. Its a 30A 120V, not 240V.

My Toy Hauler has a 50 amp service and I keep it beside the detached garage under a 36' long carport/shelter. I installed a 50 amp recpt. on the side of the garage to plug it into. I have a 100 amp panel in that garage so it was a pretty simple thing to do. Weatherproof outdoor box/recpt was about $35 and 50' of 6/4 MNB cable was an additional $120 or so. Misc fittings etc another$15-$20, so the total project was well under $200. The catch is, I'm a Journeyman Electrician so there was no installation cost as I did all the work myself. To have it done professionally, would likely be in the 600-$700 range. A 30 amp service would be slightly less.

That is the correct recpt, just make sure it is installed in a NEMA 3R rated enclosure (outdoor approved useage).

We had a 50 amp box mounted on the side of the garage with the panel in our basement for the electrician to add the breaker at the panel run the wiring and a subpanel in the garage and then to the box outside it cost us $950 Canadian. Best money we ever spent. Plus my neighbor has a welding machine and often borrows my 50amp when he needs to weld something and will throw me some money to cover power and I am sure a little more.

My dad put in a 30A for our Class A back in high school (2003 Beaver Marquis 42' - actually had a 50A hookup but that was not needed for driveway use), now I have the house and my TT and it works great. He made sure to get heavy gauge wire that is rated to be buried in the ground (we ran it about 30 yards buried to the TT from our garage).

I paid for 2 different 30a RV outside outlets. #1 at the WA coast on a 4x4 post.
With wiring running around 20 to it was under 200 bucks in 2008.
#2 At my home, I added one to the garage. It was 200 bucks in 2006 wire run was maybe 30ft from the breaker box. Both done by licensed electricians.

I installed my own 30A service at two sites on our property. One is a bit short for parking the RV but I use the other site which is actually a pad now. Put a box on the side of the breaker box and put a 30A RV outlet inside the weather proof box. If memory serves, I used 6 ga. wire to connect to the outlet. Ground goes to the ground strip, white to the common ground (neutral) and black to the Hot lead on the 30A breaker. It took all of 15 minutes or so. I did shut off the power for safety while doing it. I think the box the plug comes in tells you what wire to use for what length and although 6 ga may have been a bit overkill, I had plenty as I have run my own feeder lines and wired up my four shops using it. If you live somewhere where there is an local govt electrical code, have an electrician do the work; buy the stuff yourself at a box store. Even an idiot like me can wire this outlet to code (we don't really have one where I live).

Another route is to do what I did before I got 30A RV service at the house for the AC. Bought some thick board and made it fit the escape window. I forget how I kept it from falling out, but then bought a $99 window AC at a big box store and cut an opening in the wood to slip the AC thru. Worked great! Just another option.

Joe, George brings up a good point. If you are comfortable with doing the wiring you could save a lot. Even if there are inspections they just generally make sure you comply with standard wiring guidelines (need to know them). We have building/electrical inspectors but I wired both my shops (electrician installed mast and breaker panel) - one a real power hog. Inspector reviewed my installation of dozens of outlets, lights and 220v receptacles plus the wiring of the breaker panel and installation of the breakers. Said the tidiness of wiring looked better than most of the installs he reviewed. So, you can do it if you're comfortable and save a few bucks.

Thanks for all of the help. I actually have done wiring and could probably manage this, but with the permit process and inspections here in our city thought it best to have it done by a licensed electrician. The 15' distance is for the trailer power cable, from the breaker box to the outlet is just 2- 3' below, same wall, so very easy installation, and I have an unused 30 amp breaker in the box. It's just drill a hole in the wall, run a cable down and out, attach the outlet. I have run the AC with 20 amps before, but when I tried it with the fridge on electric it blew the breaker after about 20 minutes. I think the first thing to try is the fridge on propane, but of course, will have to wait now until about July when we need the AC again.

Pull the permit, get-r-done, and have it inspected. Improve your self confidence. Don't be intimidated by "you need a Licensed …"

Is the 20 amp circuit powering anything else? I installed a dedicated 20 amp circuit just inside the front of the garage. It only has one receptacle, so the RV is the only thing plugged into it.

Just the garage lights, which have been off when I tried it. Probably was the fridge on electric.

I had one of the Orange outside extension cords. 1 of the heavy duty looking ones. Well it wasn't and that is what was tripping my breakers. Replaced it with a heavier cord and my problem was solved. Just a thought.

Another option that I went with......installed a female, matching cord cap on a length of #8 SO cable at the panelboard. Roll it out or in as needed thru the corner of garage door.......No holes to drill in house and out of sight when not needed. No need for waterproof either as I can run the cord from camper inside to connect if I wish. Went with #8 to compensate for any voltage drop.

you can run one A/C from 20 amp. is it 15 or 20 amp?

and cost to upgrade just too many variables. figure $300-500 if not too much work involved. go to 50 amp is you go that way.
