I am trying to figure out which awg of wire I need to get for my new, 160 amp, alternator. I found this chart which shows the resistivity/length of different wire gauges. Chances are that I will not be using 160amps but I want to make sure that my wiring is adequate in case I ever draw a large amount of current. If I need 4 feet of wire between my alternator and battery what size would be the safest?
Also, what is the difference between chassis wiring and "power transmission"?
