Tinned copper, PVC insulation, red and yellow conductors, 100 feet on the spool. UL and ABYC certified so it passes survey without a second look.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis is Sea-Dog's 12\/2 AWG flat duplex, sold as a 100-foot length. Two 12-gauge conductors run side by side in a single flat jacket, one red and one yellow. That color pairing is no accident. Yellow is the ABYC standard for DC negative and red for DC positive, so when you wire in bilge pumps, cabin lights, accessory panels, or livewell circuits, the run reads correctly to the next person who opens the panel. Nothing to guess at a year from now.\u003c\/p\u003e\n\u003cp\u003eThe conductors are tinned copper, not bare. On a boat that matters more than it does anywhere else. Salt air and bilge moisture chew through bare copper strands from the ends inward, and you end up with green corrosion creeping up under the insulation and voltage drop you can't explain. Tinned strands shrug that off. It's the difference between a run you do once and a run you're chasing down in three seasons.\u003c\/p\u003e\n\u003cp\u003eTwelve gauge is a good middle-of-the-road size. It'll comfortably handle most accessory loads on boats under about 30 feet, and the flat duplex jacket makes it easy to run through tight chases, staple along a stringer, or snug behind a headliner without the two conductors wandering apart. The PVC insulation is abrasion resistant and stays flexible in the cold, so it won't crack when you're pulling wire in a chilly spring fit-out.\u003c\/p\u003e\n\u003cp\u003eThe 100-foot length is the practical size for a re-wire or a new install where you've got several circuits to feed. Buy it once, cut what each run needs, keep the rest on the spool for the next project. And because it carries both UL and ABYC certification, it's the wire you want in the boat if it ever goes across a surveyor's desk or an insurance inspection.\u003c\/p\u003e\n\u003cp\u003eOne note: this is two-conductor duplex, not triplex. If you need a dedicated safety ground alongside your positive and negative, that's a three-conductor run and this isn't it. For straight positive-and-negative DC circuits, though, this is exactly right.\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 conductors handle most DC accessory loads on boats under roughly 30 feet\u003c\/li\u003e\n  \u003cli\u003eTinned copper strands resist the corrosion that eats bare copper in salt air and bilge damp\u003c\/li\u003e\n  \u003cli\u003eRed and yellow conductors follow the ABYC DC color code, red positive and yellow negative\u003c\/li\u003e\n  \u003cli\u003eFlat duplex jacket runs clean through tight chases and stays put along a stringer\u003c\/li\u003e\n  \u003cli\u003ePVC insulation is abrasion resistant and stays flexible in cold-weather fit-outs\u003c\/li\u003e\n  \u003cli\u003e100-foot length feeds several circuits from one spool for a re-wire or new build\u003c\/li\u003e\n  \u003cli\u003eUL and ABYC certified, so it passes survey and insurance inspection\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 does 12\/2 mean on this wire?\u003c\/summary\u003e\n    \u003cp\u003eIt's two 12-gauge conductors in one flat jacket.
