Well, that chart sure explains why our trucks' original wiring doesn't smoke with >30 amp loads. Looks like wire length is just as critical as wire size.
Something else: Although the 12 ga wire running across the radiator support from the battery to the factory "splice" (on the drivers side of the radiator) carries current to the fuse panel, some of that current is supplied by the alternator. And the splice-to-fuse panel wire is only 4.5 ft feet long.
