Topic: 50 Amp Power Cord

Posted By: Duck on 01/10/11 08:32am

The 50 amp power cord that came with our trailer is stiff and a real pain in the but to handle. The MH next to us has a 50 amp power cord that looks a little smaller in diameter and much easier to coil up. What could be the difference between the two cords?

The insulation determines the physical size of the cord. The conductors (wires) are both rated to handle the 50 amp current.

Our 50 amp cord is 30 ft long...sites we frequent only require a 12 to 15 ft long cord.
Should I invest and carry both size cords ?
Where would I find the short cord ?
Thanks

This one looks interesting. Not sure where they are sold. Flexible, handle to unplug and led indicator.

I use a 50amp that goes down to 30amp which is smaller in diameter 90% of the time, much easier to handle. I still carry my 50amp cord if I'm in hot climates because that's the only way I can run my two AC's.

I had the same problems and my cord had some damage so I got one from Glendining products. Much more flexible high quality cord but a bit expensive. I haven't checked it at 0deg. but still very flexible at 40deg. I bought direct from them they will sell you the length you want.

I cut my 30 footer in half & put a new receptacle on one end & a new plug on the other. Total cost was $53 from Camping World. I use one half most of the time.

The differance is the outer coating. I too had a very stiff cord and scrapped it out. Do your ends come off or is yours a molded cord. Can you unplug it from the camper or is it wired in? If you can remove the ends, get a new piece of cord. Get a S, SO or SJO cord. It will be very flexible but be prepared to pay. With scrap copper around $3 a pound that cord is going to cost some serious money.As far as having 2 cords of various lengths, I would not because every connection (Plug and outlet) is another source for resistance and chance for bad connections.(read Burning) You may have to go to an electrical supply house I doubt that Home Depot will have that cord.

My current cord has the molded marinco type fittings. The cord is not wired into the trailer.

The MH you saw had a better quality cord.
(Kinda like the tire threads - the mfgs *don't* furnish the best - simply whatever they can get by with).

You have a few choices, but (IMO) *don't* cut your cord!

Easiest:
Coil the cord in a laundry tub or some other means to make usage easier.

Next would be to buy a short(er) cord. Fifteen footers are available from suppliers.
But . . . you will need a Marinco connection which will cost almost as much as the cord itself!

Yes, you could cut your existing cord in half. You still have one section with the Marinco.
Buy std 50 amp connector/s (any hdwe store) for the original length if needed.

Drawback: If you need both sections - you now have the connection on the ground during inclement weather, and of course - when it's cut, no going back!

*If* you don't always want or need 50 amp - buy a Marinco 50 to 30 amp adaptor
(about $50) and use a 30 amp cord (about $20. - Wally).

(IMO) the *BEST*:
Powered (12V) cord reel with 50 amp cord (it's much more flexible).
Note: It's pricey - but, for me, hands down the best accessory I ever added.
Pull out as much as you need - push button to reel it back in.
I hard wired mine - pig-tail male to/from the power center to either of 2 female "options".

1. To the cord reel.
Cord reel is mounted in front storage compt with slot in door to accommodate cord when extended.

2. To the original Marinco outlet at the back of the trailer.
(When -if- I were to sell the trailer, the cord reel can be included in the deal - or move on with me.)
It also gave an option of using the original outlet at the opposite end of the trailer (campground power pedestal at rear).
I've only seen that once - don't carry the original cord anymore - just a 15' extension.

BTW it can only go to *one* power source at a time - also with or without an "inline" PI EMS.
My normal, standard set-up is: pig-tail to EMS, to cord reel.

Disclaimer:
*If* you're not handy with electrical work, seek out someone who is.

Make sure he is using 50 amp service by looking at which receptacle he is using on the pedestal.

He could be using only 30 amp service by utilizing an adapter cord that has the conversion plug on the female end such as THIS.

Probably more than most people are interested in, but some general information on cord:

S types without the "J" are 600v Extra Hard Usage Service Grade.
SJ types are 300v Junior Hard Service Grade.

Code does not specify which cord type (S or SJ) is required for an RV, only length (minimum of 25'). Although SJ cords are lighter & less expensive, they are more easily damaged. Type S cords have thicker jackets, more fillers, and are much tougher (most could be used as a tow chain).

Either can be made with a thermoplastic or synthetic rubber jacket. Thermoplastic insulations are less expensive, but get very stiff when cold, while synthetic rubber are flexible warm or cold, but cost quite a bit more than thermoplastic. To add even more confusion, there are Thermoset cord types that can have good cold flexibility.

The "O" stands for oil resistant and can be added to either weight cord.

An additional "O" stands for Outdoor, a "W" for weather resistant. If there is a "T" in the cord description, it will be thermoplastic, however some thermoplastic cords leave out the "T".

Carol Wire produces both an S & SJ "Super Vu-Tron" rubber cord, however #10 is the largest size available on a standard order. This is an extremely flexible cord even below freezing.

Coleman Wire manufactures Seoprene 105 SEOOW & SJEOOW cord that is rated as extremely flexible at cold temperatures.

More information at LEX Products and Coleman Wire.

Lastly, most of the cord you can purchase at your local big box hardware store will be thermoplastic. You will need to go to a real electrical supplier to get the better quality cords, and they will not be inexpensive.

Hi Don, Imagine taking your cord up to Michigan and trying to use it in November or April-talk about stiff. I use an old style milk crate which allows me to coil and I store it in my unit. Hope this helps
Stay safe.

That MH may be using a 10-4 cord, that is what I use as I never exceed 30 amps on each leg.

One would need to determine what the size and specs are of each conductor in the smaller 50 amp cord to see if they are adequate. 50 amp service is supposed to handle 50 amps on each seperate out of phase 110V circuit. However, many RV parks are not wired that way.

Same here twist locks on 10/4 30’ 20’ 15’ lengths 65’ if needed most of the time the 15’ does the job. Two 30 amp breakers on the pedestal end of the cord. Have yet to trip these breakers. I have used the 65’ in extreme situations.

My thoghts exactly.

Myself, I would consider striking up a conversation and ask him.


I talked to him and it is 50 amp.

The power cords on the MH had a power cord electric reel that would probably require the more flexible, expensive, cord.

The difference between the two cords is that the MH cord next to you is smaller and easier to coil up.[emoticon]

I have found the ambient temperature has a lot to do with the stiffness of my 50 amp cord. During winter camping (Southern winter camping), I find I really have to wrestle it to coil in up. Sometimes I almost lose!
I too have an extension. I had one too many times where I could not park my trailer where I wanted due to the reach to a poorly sited electrical service post. Fort Wilderness was a prime example.

I'm glad this topic came to light again, I know now what I'm going to do. I have now a 30 AMP 25' cord, I'll be buying an adapter plug that will connect to my trailer and allow me to use my 30 AMP cord to avoid struggling with the 25' "stiff 50". I'll keep the 50 AMP cord bundled in the basement until I "need" to use it. Most of the time I can easily get away with 30 AMP hook ups.
