RV 100ft Extension cord question

I just picked up my 2020 cougar 26RBS today and I want to install a 4 prong 240v outlet on the back of my house and from there run a 100ft 6 gauge exterior grade extension cord to the camper I will have to build this myself. My question is do you have any advise or suggestions on this, it will be a 50a panel that the extension cord will plug into.

Thanks

Fran

 

Why so far from the house?
Can you put a Pedestal at the camper location and run power to that underground and then use a short jumper to the camper,usually the 30' cord in the camper will reach or at least if I were parking that one at home I would try to have it work that way.

 

EZDOG,
I could do that but I am planning on selling the house in 2 years and I would remove the 50 amp panel form the back of my house before the house goes on the market

 

I don’t know a lot about electrical. But in my experience, the further I had to run an extension cord, depending on the draw I was going to be placing, the thicker gauge I had to go. Otherwise the cord would start to get hot.

 

You would be better off and much safer to do what @ezdog suggests because running that 100 foot 240 VAC extension cord is risky just one accidental hit from something can really be bad news, The wire sizing certainly will handle the amps. what I did because I have a pad that is 80 foot from the power source I put the panel at the house ran under ground cable to an Post and put a marine type outlet on the post and protected the cable coming up the post with outdoor grade PVC conduit and it has been that way for 3 years now with no issues.

Other thing is do you really need 50 amps? what is the expected load?

 

Electrically that will work. If mine, I'd bury it or surround in perhaps schedule 80 for protection if left above ground. Otherwise have fun with the new trailer!

 

Thanks for input I want to be sure I am not doing something I shouldn't . If I had the extension cord out and plugged into the camper It would be very temporarily and raise off the ground, and lots of caution tape.

We run 50amp 3 phase cables all the time but for this I would highly recommend doing a in ground install as suggested. Much safer and will last your 2 year mark. You take a chance running 220v-240v it can very easily get damaged and or cause damage. The weather alone will have an effect on the longevity.

 

And you won’t have to look at caution tape.

 

Sounds like you need an SEOW cord aka spider box cord and a nema 14-50r for the rv connection.

 

I would think you'd only need 50a if you're planning on running AC and/or Fridge. Otherwise seems like a lot of work to run that charge all that way. If that's the case, then I agree underground would be the way to go.

 

Um....aren’t campers all 120vac?

 

Commercial journeyman electrician here..
I'm assuming with that length of trailer it has a 30A hookup???
If you don't already have the 4 wire #6 cord on hand you might shit your pants when you see what 100' will cost.
Like others have said I'd run it in pipe or direct bury wire.
At 100' long you won't see a lot of voltage drop and will be fine running #10 wire on a 30A breaker.
Let me know if you have any questions

 

It'll be fine but hand trenching just enough for cover and dropping in some PVC and stranded is going to be a hell of a lot cheaper. Probably less than half. However, if you just want to lay the cord on the ground, an SO cable will do the trick. They survive on jobsites much longer than 2 years and see WAY harsher conditions than what you've got going on.

 

I just googled your trailer and saw it is a 50A, sorry.
Not code but a safer option than cord laying on the ground if you want it temporary, run thhn wire in PVC conduit on the surface to a post with a RV plug next to your trailer

 

That is what my brother runs to his on hunting ranch. Ranch owner is an electrician and he said 10 ga was fine. My brothers trailer is a 28' Jayco. Runs underground from box on pole to RV hook up.

 

Thank you everyone for your advice and after listen you guys I realize I’m definitely going to do an underground cable I will have an electrician come in and do the box connection and the plug by the RV but I can do the digging

 

You can do the box connection. It is simple. If you are going to leave it when you sell the ed house you will need to have an electrician inspect it.

 

Yeah, it'll only help your property value to leave it in place, if you do make sure the ditch is deep enough for your county code. Probably 18", have fun!

 

You probably already know this but renting a ditch-witch is the only way to go in digging a long straight ditch.

the only thing running when at home is the battery charger. occasionally the fridge if packing up. not sure you even need 30A unless you plan to run the AC.

 

Thats true and i would prob same a ton of cash
