[QUOTE="RivRunR, post: 255611, member: 1928"] I'm not sure what you mean by [i]"the main positive line on the fuse panel has 12AWG coming out of it"[/i]...do you mean the panel came equipped with 12AWG as the main feed...the #1 circled below? [ATTACH type="full" alt="Blue Sea 4376.jpg"]35775._xfImport[/ATTACH] If that's what you're looking at, I'd still go with 6AWG [b]IF[/b] you can make a direct connection to the panel. Overkill on the wire gauge won't hurt anything, and assuming that your CB is correct at 40A, then 12AWG seems small. If you can't replace the installed 12AWG lead with the 6AWG, then you need to calculate your total amp draw coming thru the panel to make sure 12AWG will handle the load by checking one of the online charts. Don't try to splice/connect the 6 to the 12, that's just another potential fail point. And you can leave the battery-to-breaker at 6AWG regardless of what you end up with on the breaker-to-panel lead. For the cig lighter it depends on the length of run, but again overkill on the gauge doesn't hurt, so you can run the 16AWG (both sides) if you can make direct connections at the plug. [/QUOTE]
