[QUOTE="Hydrilla, post: 115690, member: 863"] I bought a 12V plug from BPS that according to the packaging is rated for 50 amps. My trolling motor pulls 39 amps and recommends recommends 6 gauge wire from the receptacle back to the battery, and a 50 amp manual reset circuit breaker. Here's what doesn't make sense to me- the wire that goes to the receptacle is 8 gauge wire, which according to the wire you can buy from the hardware store is rated for 40 amps. 6 gauge wire is rated for 50 amps. So it seems that even if the plug is rated for 50, because of the 8 gauge wire being a weaker link, it's actually rated for 40 amps. All that just to ask if you think I'd be ok for my wiring going back to the battery to be 8 gauge wire? If so, should I use a 40 amp inline circuit breaker, since 50 amps could fry 40 amp rated wire? I know I'm probably overthinking this, I just don't want to create a fire hazard. [/QUOTE]
