Tinned copper conductors, PVC insulation, red and yellow leads, and a flat bonded jacket that's easy to route and staple down. 100 feet on the spool, UL and ABYC certified.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eSea-Dog's 18\/2 AWG duplex wire is the everyday feeder for the low-draw circuits on your boat. Nav lights, courtesy lights, gauges, bilge sensors, an accessory feed at the helm. If it doesn't pull much current, this is the wire that carries it. Two 18-gauge stranded conductors ride side by side in a flat, bonded jacket, so it's easy to route and lies flat behind a panel or along a stringer.\u003c\/p\u003e\n\u003cp\u003eHere's what matters on the water: every strand is tinned copper. That thin coating of tin is what keeps salt air and bilge moisture from turning bare copper green and brittle over a couple of seasons. Bare wire corrodes from the cut end inward and you never see it until a light flickers. Tinned copper holds its conductivity and takes a crimp that stays tight. It's the difference between wiring you do once and wiring you chase down every spring.\u003c\/p\u003e\n\u003cp\u003eThe two leads are colored red and yellow, following the ABYC convention where red carries the positive and yellow serves as the DC negative return. That makes troubleshooting down the road a lot simpler for the next person at the helm, even if that person is you three years from now. The PVC insulation shrugs off fuel, oil, and the odd splash, and the flat encasement staples down clean without twisting.\u003c\/p\u003e\n\u003cp\u003eYou get 100 feet on the spool, enough to knock out several runs without splicing mid-circuit. And it's UL and ABYC certified, so it meets the standards a surveyor or insurer expects to see in a marine DC system. Match the gauge to your load and run length. 18 AWG is sized for low-amperage circuits, so step up to a heavier gauge for pumps, windlasses, or long high-current runs. For the small stuff, this is exactly the wire you want, and a spool aboard means you're ready for the next project too.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e18 AWG stranded conductors, sized for low-draw DC circuits like nav lights, courtesy lights, gauges, and sensors\u003c\/li\u003e\n  \u003cli\u003eTinned copper strands resist corrosion from salt air and bilge moisture and hold a crimp that stays tight\u003c\/li\u003e\n  \u003cli\u003eTwo-conductor duplex with red and yellow leads follows the ABYC DC color convention for easy troubleshooting\u003c\/li\u003e\n  \u003cli\u003eFlat bonded encasement routes cleanly behind panels and staples down flat without twisting\u003c\/li\u003e\n  \u003cli\u003ePVC insulation shrugs off fuel, oil, and moisture\u003c\/li\u003e\n  \u003cli\u003e100-foot spool covers several runs without splicing mid-circuit\u003c\/li\u003e\n  \u003cli\u003eUL and ABYC certified for marine DC wiring\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 18\/2 duplex wire used for?\u003c\/summary\u003e\n    \u003cp\u003eIt's sized for low-amperage DC circuits: nav and courtesy lights, gauges, electronics accessory feeds, and sensors.
