It's the everyday workhorse gauge for 12V DC runs, nav lights, pumps, cabin lighting, and accessory feeds, and it's UL and ABYC certified for new installs and surveys.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis is the Sea-Dog 14\/2 AWG flat duplex cable, sold as a full 250 foot spool with one red and one black conductor. It's tinned copper wire built for the salt air and damp bilges of a real boat, not the dry, easy life of a car dashboard. If you're rewiring nav lights, dropping in a new bilge pump, feeding an accessory panel, or you just want a spool of honest marine cable on the shelf for the next job, this is the everyday gauge that handles most 12V DC runs on the boat.\u003c\/p\u003e\n\u003cp\u003eThe thing that makes marine wire marine wire is the tinning. Every copper strand is coated in tin, so when moisture finds its way in, and on a boat it always does, the copper underneath doesn't turn green and go brittle. Bare automotive wire wicks water right up the strands and corrodes from the inside out. Tinned copper shrugs it off. Boaters who've pulled panels apart after ten years of salt-water service regularly find tinned runs still bright and clean, where the cheap stuff would be crumbling green. That's the whole point of paying for the good stuff, and it's why the surveyors care.\u003c\/p\u003e\n\u003cp\u003eThe flat encasement is the other detail worth understanding. Two conductors sit side by side in a single jacket, so the cable lies flat instead of rolling. That flat profile slips behind a headliner or along a stringer far easier than a round bundle, and it's simple to clamp down tidy. One caution from folks who've run miles of it: don't force it around tight 90 degree corners. Flat duplex will take a permanent kink if you yank it around a sharp bend, so give it a gentle sweep instead.\u003c\/p\u003e\n\u003cp\u003eFourteen gauge is the workhorse size for 12V DC branch circuits. Think nav and anchor lights, cabin and courtesy lighting, small pumps, electronics power feeds, and most accessory runs. The one thing to keep an eye on is voltage drop. The longer the run, the more voltage you lose along the way, and ABYC wants critical circuits like nav lights held to a 3 percent drop. On the boat that means a long round trip to a bow light can push you toward stepping up to 12 gauge instead. Measure the round-trip distance, not just the one-way, before you commit a reel to a long run. Get that right and 14 gauge covers the vast majority of the circuits on a typical boat.\u003c\/p\u003e\n\u003cp\u003eThis cable is UL and ABYC certified with PVC insulation and the red and black conductor pair that's standard for DC positive and negative. If you're doing a new install or heading into an insurance survey, that certification matters. Surveyors and inspectors flag non-tinned, non-rated wire the moment they see it, and a certified tinned cable keeps the whole job above board.\u003c\/p\u003e\n\u003cp\u003eA few install notes from people who do this for a living. Support the run about every 18 inches so it doesn't sag or chafe. Anywhere the cable passes through a bulkhead or a drilled hole, drop in a grommet, because the number one failure on these runs is the jacket chafing through where it rubs bare fiberglass. And finish every termination with adhesive-lined heat-shrink connectors so water can't creep into the strands at the joint. Do that and a run of this wire will outlast most of the gear it feeds.\u003c\/p\u003e\n\u003cp\u003eAt 250 feet, this spool is more than most single projects need, which is exactly why boaters like it. Wire one system now, keep the rest on the shelf, and the leftover covers the next accessory rewire without another trip to the store. It's the kind of cable you buy once and chip away at for years, and every foot of it is the same quality tinned copper as the first run you pull.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e14\/2 AWG duplex construction pairs a red and a black conductor in one jacket for clean 12V DC positive and negative runs\u003c\/li\u003e\n  \u003cli\u003eTinned copper conductors resist salt corrosion and stay bright for years where bare copper would turn green\u003c\/li\u003e\n  \u003cli\u003eFlat encasement lies flat behind headliners and along stringers, easier to route and clamp than round cable\u003c\/li\u003e\n  \u003cli\u003eStranded conductors flex with the bends and vibration of a moving boat without work-hardening\u003c\/li\u003e\n  \u003cli\u003ePVC insulation rated for wet marine service\u003c\/li\u003e\n  \u003cli\u003e250 foot spool covers a full rewire plus spare for future projects\u003c\/li\u003e\n  \u003cli\u003eUL and ABYC certified, so it passes surveys and insurance inspections\u003c\/li\u003e\n  \u003cli\u003eStandard 14 gauge sizing suits nav lights, pumps, cabin lighting, and accessory feeds\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 can I power with 14\/2 AWG duplex wire?\u003c\/summary\u003e\n    \u003cp\u003eIt's the standard workhorse size for 12V DC branch circuits: nav and anchor lights, cabin lighting, small pumps, electronics feeds, and most accessory runs.
