As a matter of fact, the longer the distance to fault, the more resistance in the wire, and thus, the less fault current the wire will experience. A longer wire is somewhat safer in this regard.
You said it yourself there, "more resistance". Which directly mean more heat. Basic physics. Resistance produces heat. Ever touch a resistor. They get hot.
(Copper wire)
gauge - resistance per foot
4 - .000292
8 - .000739
4 feet of 8 gauge will have 4(.000739) = 0.002956
20 feet of 4 gauge will have 20(.000292) = 0.00584
Put it at close to double the resistance. hence almost 2 twice as much current can run thought the short 8 gauge. Which means the the fuse on by your battery on the 4 gauge will blow before you even come close to pulling the max current for the 8 gauge.
