T&T: Battery cable

There might be an issue with the Insulation Temperature Rating. Maybe with an extra slit loom cover that is fire rated.

I have a question about the statement that welding cable is not suitable.
Admittedly it is not tinned but none of the other wires in my 30 year old
boat are tinned and they are still functioning fine with no sign of heating
at any of the terminals.  In a corrosive environment tined cables would have
some advantage but in the interior of most trawlers this would not be a
problem unless the boat takes on water and then you should replace submerged
cables regardless if they are tinned or not. The outer sheath of a welding
cable is designed for extremely rough service of being dragged around on
shop floors or outside in inclement weather where abrasion, oil, fuels and
water are a constant problem so I think that welding cable would stand up as
well or better then marine cable in a marine environment.  Welding cable
also uses extremely fine strands of wire so it is very flexible and stands
up well to vibration and movement and has excellent current carrying
ability. If closed end fittings are used and covered with adhesive shrink
tubing I suspect they could even be submerged in salt water with no ill
effects.

Is this one of those code things that does not really make sense?
