I can't believe there are electricians chiming in here and not questioning the use of an 80 amp CB on a circuit that is clearly not designed for 80 amps.
We are talking about less than 4 feet of wire at 12volts.... 10 gauge wire should be able to handle 85 amps. longer wire less amps. 80amps should blow the CB before toasting the wire. But yeah, a larger wire would be better. Guess the question is the gauge of the existing wire. Full disclosure, I am not an electrician, don't play one on TV either.
