My 20 year old jumper cables have rotting insulation that is cracking and falling off so it is time for some new ones. I know bigger wire is better and some clamps are cheaply made and do not transfer current well. Longer ones are better but how long do I need for a pickup truck and a SUV before they get too big and heavy.
Cheap ones use extra thick insulation to save on copper. How big a wire is needed for occasional use. I see wire size from #0 to #14. Any recommendations on what makes a good clamp end. Features I should look for. Is rubber still the best insulation in cold weather, more flexible.
I would prefer to buy premade rather then source clamps and cable and make my own. I suppose. a welding ground clamp would carry the currents needed with no problems and no insulation.

Why do makers think insulation for 12 volts has to be several times thicker then the stuff for 600 volts?
