Length of 30Amp cord?
What is the longest a 30Amp cord can be without resistance of the length causing a problem? I ask this because I can't park my camper that close to my house, and there are times I would like to hook up the camper to 30Amp.

It would probably be easier if you can tell us how much you need and we can work it out from there.

I probably need about 120 feet, but I may be able to get by with 100 feet.

OK. Sorry for more questions but do you want it to be temporary or permanent?

Another factor is how much current you want to draw.

Well if you try and run a extension cord type cable that far it is going to get expensive. I personally would use #8 to go that far.

A full 30 amps is a lot to push through 100 feet of cord. But if you are drawing a lower amount, like closer to 15 amps, a 12 awg cord should be okay, and a heck of a lot cheaper.

My 30 amp box is on the side of house by driveway and I park MH in back yard and on occasion when kids come they stay in MH and I use the MH cord and two 30 amp extensions. I believe they are 25 or 30 ft each so I am probably 90 ft or so. A/C has always worked fine. Have had the 30 amp cords for years and believe I may have purchased at Walmart. Have never had any issues.

A #8 would be over the 3% amp drop rule but it would work, it you want to do it right go with #6 at 100' and not worry about it.

mtbbrewer74 I know I kick this horse every time this subject comes up.
If you do not have a EMS get one. It will help you from having any problems with this kind of stuff. If you do not have enough power it will shut you down.

You could likely run a fixed connection and a breaker box at the site for the cost of that much extension cord.

That is exactly what I did Norty. Well over a hundred foot run and a permanent box on a pole. Water line as well. All set!

I ran #10 wire but sometimes wish I had used #8. I noticed my power cord fells warmer than I like when the ac runs longer on hot days, which we are having to much of lately.

Borrowed ,or was given, a 50 foot 30 amp cord by a campground once due to the vicinity of the power box & plugged my existing power cord (25ft) into that one without issue, A/C ran fine.

There is an app called "Southwire Voltage Drop Calculator" which I used for a solar power installation to determine the wire size required for different parts of the project. Basically you enter the distance of the run, the number of amps carried, and it will give you the minimum size wire for a 3% voltage drop. You need to know the size wire for your 30 amp cord and the app will tell you the length that will allow the current to flow at full voltage. Otherwise the cord will get very hot and voltage will drop, causing brownout and appliances not working correctly.

I like this idea as well, not hooking together multiple cords which invite arcing issues and water intrusion causing shorts would be a plus. Also having the box right by the camper so you could have a dedicated breaker close by in case of emergency would be good too. A friend did this at his property and it was an easy task.
