Tinned strands fight corrosion in the bilge, the flat profile snakes through tight spaces, and it carries the UL and ABYC label your surveyor wants to see.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eSea-Dog built this cable for the wet, salty places where regular wire gives up. It's 10\/2 AWG, which means two 10-gauge conductors, one red and one black, run side by side inside a single flat jacket. Every strand is tinned copper, so it shrugs off the corrosion that turns bare copper green and brittle after a couple of seasons. You get a full 100-foot roll, enough to wire up most of a small boat's DC system or knock out several longer runs on a bigger one.\u003c\/p\u003e\n\u003cp\u003eThe red and black color code tells you what this is for. Red is your positive, black is your negative return, and that's the standard for 12V and 24V DC circuits. Think bilge pumps, cabin and nav lighting, livewell pumps, electronics feeds, and short runs to a windlass or trolling motor. Ten gauge is a common size for DC circuits in the 25 to 30 amp range, but always size your run off an ABYC voltage-drop table, not just the amp rating. On a long pull, voltage drop matters more than ampacity. If your run gets past 25 feet at higher current, step up to 8 gauge instead.\u003c\/p\u003e\n\u003cp\u003eThe flat encasement is the quiet hero here. A flat jacket lies down against a stringer or a bulkhead and feeds through a tight lazarette or a packed conduit a lot easier than a fat round cable. Just don't yank it hard around a sharp 90. Flat duplex will kink if you fight it, so take your time on the tight turns and use a gentle radius. Once it's run, the flat profile also makes it easy to clamp down neat and flush.\u003c\/p\u003e\n\u003cp\u003eTinned copper is the whole point of marine-grade wire. We've pulled untinned wire out of bilges that had gone hard and cracked at every bend, while the tinned stuff next to it was still flexible and bright. This cable stays workable for years in a damp bilge. When you terminate it, use adhesive-lined heat-shrink ring terminals sized for 10 gauge and crimp them properly to hit ABYC torque and pull-test specs. Skip the open-barrel automotive crimps. They corrode and back out.\u003c\/p\u003e\n\u003cp\u003eAbout that 100-foot roll: it sounds like a lot until you start pulling. A full DC rewire on a 25-foot center console can eat most of a roll once you account for the twists, the service loops, and the runs you'd rather not splice. If you're doing a whole system, it's worth buying two rolls up front so you're not stopping halfway to order more. Uncoiled and measured, a roll also tends to come up a touch short of the marked length, so plan your longest runs with a few feet of margin.\u003c\/p\u003e\n\u003cp\u003eOne thing to watch: any wire that rubs a hard edge will chafe through eventually. If your run crosses an aluminum stringer or a sharp bracket, add split loom or a chafe guard where it passes. And because this cable carries the UL and ABYC label, it passes survey inspection without you having to dig up extra paperwork, which is a real relief on an older boat.\u003c\/p\u003e\n\u003cp\u003eIt's tempting to grab cheaper wire from the auto parts store, but that's a mistake on a boat. Standard building or automotive wire uses bare copper and thin insulation that wasn't made for constant humidity, salt air, and vibration. This is boat cable. The tinning, the finer stranding, and the tougher jacket are all there for a reason, and they're the difference between a connection that lasts a decade and one you're chasing with a multimeter next spring. Whether you're rewiring a center console, sorting out a sailboat's DC panel, or just replacing a tired old run, buy the length you need with a little extra, and wire it once.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e10\/2 AWG duplex construction, two 10-gauge conductors in one flat jacket for clean two-wire DC runs\u003c\/li\u003e\n  \u003cli\u003eTinned copper strands resist corrosion and stay flexible for years in a damp bilge\u003c\/li\u003e\n  \u003cli\u003eRed and black color code follows the standard for 12V and 24V DC positive and negative\u003c\/li\u003e\n  \u003cli\u003eFlat encasement lies flat against stringers and bulkheads and feeds through tight spaces\u003c\/li\u003e\n  \u003cli\u003ePVC insulation and outer jacket built for salt air, humidity, and vibration\u003c\/li\u003e\n  \u003cli\u003e100-foot roll covers a small boat's DC system or several longer runs\u003c\/li\u003e\n  \u003cli\u003eUL and ABYC certified, passes survey inspection without extra paperwork\u003c\/li\u003e\n  \u003cli\u003eFinely stranded for flexibility, easier to route and terminate than coarse-stranded wire\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\u003eIs this AC or DC wire?\u003c\/summary\u003e\n    \u003cp\u003eIt's DC wire.
