It's stranded tinned copper, so it flexes with the hull and shrugs off the corrosion that kills solid automotive wire. A hundred feet on the spool covers most rewires with plenty to spare.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis is Sea-Dog's 12-gauge primary wire in red, wound onto a 100-foot spool. If you've done any wiring on a boat, you know why the color matters. Red is the one you run to the positive side, and having a full spool on the shelf means you're not splicing three short leftovers together to reach the helm.\u003c\/p\u003e\n\u003cp\u003eWhat makes it marine wire and not the stuff off the auto-parts rack is the conductor. It's tinned copper, stranded. Every one of those fine copper strands wears a thin coat of tin, and that coating is what stands between your wiring and the slow green corrosion that creeps up bare copper in a salt-air bilge. Solid automotive wire work-hardens and cracks where it flexes. Stranded wire bends with the boat and takes the vibration without fatiguing. The PVC insulation seals the whole run against moisture.\u003c\/p\u003e\n\u003cp\u003eTwelve gauge is the workhorse size for most of what you add to a boat: bilge pumps, nav and courtesy lights, a stereo feed, livewell pumps, the power lead to a fish finder or chartplotter. It's heavy enough to carry those mid-size loads over a typical run without a meaningful voltage drop, and thin enough to pull through a rigging tube or a crowded chase without a fight.\u003c\/p\u003e\n\u003cp\u003eA word on picking gauge: match it to the load and the length of the run, not just what fits the terminal. If you're feeding a windlass, a thruster, or an inverter, you'll want to step up to heavier wire. But for accessory circuits and the everyday rewire, 12 AWG red is what most of these jobs call for.\u003c\/p\u003e\n\u003cp\u003eOne hundred feet is enough to rewire a small center console top to bottom, or to keep on hand for the odd repair and addition that always comes up mid-season. Pair it with the matching black or yellow for your negative returns and you've got both sides of the circuit covered.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e12 AWG stranded conductor, sized for bilge pumps, lighting, and electronics feeds\u003c\/li\u003e\n  \u003cli\u003eTinned copper strands resist the corrosion that eats bare copper in salt air\u003c\/li\u003e\n  \u003cli\u003eStranded core flexes with the hull and shrugs off vibration without fatiguing\u003c\/li\u003e\n  \u003cli\u003ePVC insulation seals the run against moisture\u003c\/li\u003e\n  \u003cli\u003eRed jacket for clean, easy-to-trace positive DC runs\u003c\/li\u003e\n  \u003cli\u003e100-foot spool covers a full small-boat rewire with wire to spare\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Sea-Dog reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat is this wire used for?\u003c\/summary\u003e\n    \u003cp\u003eIt's primary wire for the positive side of low-voltage DC circuits on a boat: bilge pumps, nav and courtesy lights, stereo feeds, livewell pumps, and power leads to electronics.
