Replacing 50A Electric Cord

OK, so I replaced the 35'r with a 30 foot cord, and my electrician is making a 10 foot extension from the original. Feel comfortable now, and ready to hit the road again!

You might want to check out boat cords. They are much lighter and more flexible.

No. Boat and RV cords are not interchangeable. The inlet end to the boat or RV is the same but the pedestal end is different.

All the RV power cords I've seen are S, not SJ rated. In any case, look for rubber or SE--- designations. Cheaper cord will be thermoplastic (ST--), stiff in cold weather. Rubber & elastomer (the E) are much more flexible. For example SEOOW is a good choice. Stay away from STOW and the like...

SOOW is by far the best choice, we full time our cord has seen heat and direct sun, cold and covered with snow, and a slightly flooded site and been under water (cable only not ends). The cable is still as good as new and still easy to coil into the 3 gallon bucket when travel.

It would be interesting to compare our cords side by side. Yours has inner insulation designation “O” and mine does not. I believe mine is a smaller diameter as my ground is #8 and yours is #6 and without the insulation it makes mine smaller. Will this may make it less durable? I don’t know but I do know the conditions my cord was designed to handle on Construction Sites and no doubt is more than needed in the RV world.

Ron, yours might be a bit smaller, but I can't describe the thrill when I grabbed my 3 gallon bucked and started coiling the "New" 40' cable in it and it all fit! That was a great space saver over the old cable!

The old thermoplastic cable was only 25' the new as stated is 40'.

When I got my RV the store had what I call "Super flex" cords.. My 30 amp cord (it was a 50 amp rig but I had a 30 amp cord for it) was a "Super flex" I used it a lot in the winter even in SC it gets cold "Near freezing" is not uncommon, Freezing happens and "Got to worry about it" well once. and as I prepped it was NOT a problem.

The 30 amp "Super flex" cord.. cold or hot, wound up like a piece of string. real easy.

By the time you buy the cable and the cord body, you would be better off buying a manufatured cable remove the unneeded end. Another option would to buy a range pigtail and use a manufactured 50 amp extension cord.

But the manufactured cables are still mostly very heavy and hard to coil up compared to the more supple after market cords you can use. It's more about convenience and ease of use than cost savings.

Not sure about the "E" designation for the outer layer.

This pictured cord is smaller than any I have seen. It came from a Jobsite Power Box. This cord is SOW 6/3 & 8/1. "OO" must give the extra thickness.

These cord caps are good quality, Camco Yellow.
