Default Re: Does Gauge of Ground Wire Matter

The wires I had were as follows...1 gauge from battery neg. to starter and then 2 gauge from battery positive to disconnect and 2 gauge to frame from disconnect. So I'm ordering all new 0 AWG. Sound good?
Hawk - 300 amps continuous and 500 amps intermittent (i.e. during starter load) is great. I think (happy to be corrected) that the original wire was the equivalent of today's #2 AWG, so #0 AWG (which is higher ampacity than #2) should be fine.
