I've been using the coil and twist method used by sailors (as shown here http://www.youtube.com/watch?v=k2ChlCns4AU
but without the final tight wrap & knot). This requires that a the far end is free to spin around because the twist turns the rope.
I had modified this method so that when the wire gets twisted, I twist it the opposite way and put the loop on the other side of the coil. This keeps the cable from getting twisted overall. I use this on the 20 feet of cable on the 120V brick EVSE. But--it does nothing to help you get it unrolled. I have to unroll it the old fashioned way...
THEN, I watched the video! No more of the old method! I am going to learn this over/under method. As padamson1 said, I learned something new today.
