Here is that specific thread in case some people here would like to read through it.

30A to 50A Adapter Causes MH Fire

I don't have a reel but I do have the Glendinning Cablemaster which loosely coils up the 50 amp cord in a small compartment at the rear of my coach. I only remove enough to reach the pedestal and allow the cord to drape correctly without any strain.

My cord has NEVER been hot or even warm.

I'd think if the coach mfgrs. even thought this might become an issue, their lawyers would nix them(cord reels) before the company could even find a vendor.

Best advice: Bury a thermal sensor in the coil and see how hot it gets.

I have used a 12 ga 100' cord to power a computer or two, Not a lot of load for a 12 ga cord, but the reel got uncomfortabally warm from the heat build up.. It is not just inductive heat but the fact that air can not circulate around the wires.. If they get so hot you can not hold them in your hand comfortablly worry.

The only time my RV cord has gotten that hot.. Well, it was sunlight, not current, doing the heating. (Actually it was not the RV's cord but the house's cord.. I had a 27' heavy duty cord to power the house off the RV in the event of power fail. Used it too, this day I was using it for something else, sucking peprhaps 5-010 ams on a cord designed for 30-40, and streatched full out (We needed every foot). the shaded part of the cord was COLD to the touch, the sunny part I needed gloves)

I believe most 50 amp power cords are #6 wire gauge( the ground is #8) #6 copper wire is good for 100 amps. Your 50 amp power cord is only pulling 50 amps ( I know they pull 100 but it is on each leg.) You are not going to get any where near getting that cable hot enough to melt in normal operating circumstances. Abnormal would be a short with a bad breaker or a high impedance connection. To get inductance heating would require a very special set of circumstances that would have to be manufactured for that purpose rather than just an accident. ( If you are worried about it then pull all of your cord out and find somewhere to put it where it is not a trip hazard ( I think having 30 or so feet of cord laying on the ground is much more dangerous as a trip hazard) Other wise just leave it on the reel and pull out however much you need which is a very popular way to deploy the reel.
