Power question

We have a 30 amp outlet in out garage.
I need to see if there is a certain length you should not exceed on a 30 amp power cord. Problem is our camper is parked on the side of the house and doesn't come close to reaching outlet with camper power cord and 20 ft extention. Can I safely add another 50 ft cord or would that cause issues?
An electrician quoted $700 to move 30 amp outlet to side of house.
Or can I plug the camper into an adapter so I can use a standard outlet already on the side of the house. I would like run AC (1 - 15k BTU on low) and fridge. Or would this cause issues to our AC over time? Would only run AC while packing and making beds. Currently is a sweat box.

With running the air, I would spend the money and get the 30amp installed properly. I tried everything you described and over time it didn't work out. The adapter is fine for light duty but not for air. And with the rv extension cords, just too many connections too get hot and fail overtime. It's better getting it done right and avoiding a low voltage situation that may cost a lot more in the long run.

Points to ponder:
  • Voltage drop for a 30-amp circuit at 50' using 10 gauge wire appears that it may be borderline at best.
  • In general a 30-amp circuit requires 10 gauge copper wire, but longer runs may even need 8-gauge.
  • I would recommend moving that dedicated 30-amp circuit, although that $700 figure does feel a little high. However, keep in mind that you may need a circuit breaker, wire from your breaker box, some kind of a weatherproof box, and an RV-style 30-amp socket. And depending on local codes, you may need an inspection. (RV 30-amp circuits are not the same as typical home 30-amp circuits used for appliances like dryers and water heaters.)
I see 25' 30-amp RV extension cords for $50 or less on Amazon, somewhat higher at CW. May be your best bet.



As for running the AC on a 20-amp residential circuit, ain't happening. Try it and see - you'll blow your TT's circuit breaker within seconds after the compressor kicks in. I kinda forgot myself and just tried it a couple of weeks ago. That was a whole lotta nope.

FWIW, I know my TT isn't as power hungry as yours but I run my fridge, 8,000 BTU A/C and ALL lights off of a 20A home circuit through 12AWG, 75ft extension cords... Never had a problem in the past 5 years...

I did the same with my SLX 165RB, but a 15,000 btu A/C is going run around 15 amps, possibly nearly 20, all by itself. Doesn't leave much headroom. My 13.5K btu A/C popped the 20-amp home circuit breaker in in a couple of seconds. To be sure, there may have been some household load on that circuit as well.

First, make sure that the 30 amp circuit in your garage is not 220v. Most 30 amp circuits in a garage would be 220v for a dryer, welder, water heater, etc. Second, find a different electrician, $700 is an outrageous charge to run 30 to 40 ft of 10g Romex unless you have some very extenuating circumstances.

For those running the AC on a 20 amp household circuit, consider that if it's on extension cords, the voltage drop is likely a big number. That AC compressor may be running on 106, 107, or 108 volts. The motor will run very hot, and its life will be cut in half for just about every 10 degrees C higher than normal operating temperature. The motor could be 20-30 degrees too hot.

As has been posted you need to make sure the 30 amp "outlet" aka "receptacle" in your out building or garage is 30 amp 120 volt and NOT 30 amp 220 volt. The 30 amp RV service for your travel trailer is most likely 30 amp 120 volt single pole.

Thirty amp (30A) 220 volt double pole which is commonly used for household water heaters and clothes dryers will fry your RV equipment.

This is why you need an electrician. Single pole 120V power uses One Hot lead and One Neutral lead. Double pole 220v power uses Two Hot leads! Mistakingly hooking up your RV to 220v double pole power will send electric current through the 120V hot lead and neutral lead at the same time and will result in over current to your RV electrical power systems and potentially cause serious damage.

Providing your home distribution service has enough power available you should be able to use a 25' RV extension cord hooked to your RV power supply cord. It should be a minimum of 10 gauge wire.

I use a 25' ft extension cord from my shop to my RV power cord which is also 25'. My home has a 400 amp service that is split 200 amp for my shop and 200 amp for my house.

You could go 50' plus the RV cord but that is pushing it. You start getting into voltage and amperage drops due to the increased resistance of the longer wire. That is a power quality problem common in RV parks and campgrounds

$700 is ridiculous!! I put in a 30amp shore station on a 4x4 post outside my barn. Had HD direct bury wire left over from running power to the barn so that was free for this project. The weatherproof box and necessary outlets and breakers was less than $50. This is electricity but it is not brain surgery. LIKE OTHERS HAVE SAID, THE CIRCUIT IN YOUR GARAGE IS MOST LIKEY 220 which is easy to verify by looking at the breaker in the main box. If its a double pole breaker it is 220. Its easy enough to change out the breaker and change the wiring connection to a single pole.

This would be a very small project for an electrician and the quote you got is that is what I would charge to make it worth my time to park and get out of my truck. You need to check around and find a neighbor or friend with some electrical background who would likely be able to do it for the cost of the parts and some cold beer [hold the beer until hands are out of the main breaker panel].

I do this all the time using a 50-foot 10-3 contractor grade YELLOW extension Cord plugged into a 20AMP Garage receptacle. I have to use a good HD RV30A-15A long dogbone adapter to get to my 30AMP Cord laying in the middle of the yard...

You should not have any problems at all. Since you have the 30A RV receptacle already installed just go pick up a RV 30A Extension Cord... I also got two of those I use here. When I bought I new POPUP trailer from a local dealer I just asked if they had a couple of those laying and they put two on them inside the the trailer. They use them all over their dealership display lot...

I have seen them for sale on the ETRAILER.com site...
