What is the recommended wire gauge for a 12v system battery harness? 14,12, or 10 gauge?

What is the factory harness gauge?


Thanks!

I believe it is 14 gauge. I use 14g marine wire for all my batteries with 40A circuit breaker

Thanks for the reply! Can anyone second the 14 gauge?

14 AWG with a 40A breaker is on the hairy edge of acceptability with a run longer than 2 ft round trip.

I'd stick with 14 AWG with a 30A or upgrade to 12 AWG with a 40A personally.
