unpredictable. The over current can weld the contacts, permanently on. Or it can burn the contact surface and leave some "ash" that stops making electrical contact, permanently off. It depends on the conditions in THAT fraction of the second.

'They' calculated what resistance is needed not to exceed the contacts rating. Simplest solution; a wire that limits the current by its resistance. You are correct that when the goal is to get the juice to a piece of gear fatter cable, shorter run is better.

I can't think of any practical situation where a little too big is not good and the shorter runs are better too.

From memory, a minimum length of 6 feet and maximum size of 6 SWG. (please check before using this info.)
