Three 10-gauge stranded conductors in white, green, and black, wrapped in a flat PVC jacket, on a full 100-foot spool. UL and ABYC certified, so it satisfies your surveyor and your inspector both.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis is Sea-Dog's 10\/3 flat triplex, the three-conductor tinned-copper cable you reach for when a boat needs a proper AC feed run the right way. Ten-gauge stranded conductors in white, green, and black, sealed under a flat PVC jacket, wound onto a full 100-foot spool. It's marine cable built for the environment it actually lives in: damp lockers, salt air, engine-room heat, and the constant low-level vibration of a hull working through a chop.\u003c\/p\u003e\n\u003cp\u003eThe thing that separates real marine wire from the cheap stuff at the hardware store is the tinning. Every individual copper strand is plated with tin before the conductor is bundled, so when moisture and salt find their way to a termination, and on a boat they always do, the copper underneath doesn't turn green and go high-resistance on you. Bare copper corrodes from the strand surface inward and slowly chokes off current. Tinned copper shrugs it off. That's why ABYC leans on it and why your surveyor wants to see it.\u003c\/p\u003e\n\u003cp\u003eStranded, not solid. A boat is never still, and solid conductors work-harden and fracture at vibration points over a season or two. The fine stranding here stays flexible, pulls around bulkheads and through tight chases without fighting you, and takes the flexing of a moving boat in stride. The flat encasement is a quiet nicety too. Flat triplex lies down against a stringer or in a cable tray flatter and neater than round jacket, and it's easier to secure in a run where three round cables would want to roll apart on you.\u003c\/p\u003e\n\u003cp\u003eThe white, green, and black color set follows the standard AC color convention: black for the hot line, white for the grounded neutral, and green for the safety ground. That makes this a natural fit for shore-power branch circuits, inverter and charger feeds, cabin GFCI and outlet runs, and the AC accessory circuits on everything from a weekend cuddy to a liveaboard trawler. Ten-gauge is the common choice for circuits in the 25 to 30 amp range, so it covers most of the AC loads you'll wire on a mid-size boat.\u003c\/p\u003e\n\u003cp\u003eA few notes from the dock. Give yourself dielectric grease at every termination, especially on an aluminum hull, because tinning fights corrosion but it doesn't stop it cold. Route it away from the exhaust and the hottest part of the engine room, since PVC insulation softens once you get much past 105 degrees, and cover any long exposed run in split loom to keep UV off the jacket. And don't crank your cable ties down like you're trying to cut the wire in half. Over-tightened ties deform flat cable and create hot spots. Snug is plenty.\u003c\/p\u003e\n\u003cp\u003eOne honest heads-up on the spool: a 100-foot spool of flat triplex can come up a few feet short once it's fully uncoiled, so if you're planning a long single run, measure the whole path before you cut. Better to find the tight spot with the cable stretched across the cabin sole than up at the panel with your connectors already crimped. If you've got two shorter runs to make, you'll usually get both out of one spool with room left over.\u003c\/p\u003e\n\u003cp\u003eIt's UL and ABYC certified, which is exactly what matters when an inspector or an insurance surveyor is looking over your work. Those two marks tell them the conductor size, the insulation, and the construction all meet the standards written for boats, not for houses. Whether you're rewiring an AC panel, adding an inverter, running a fresh circuit to a new galley outlet, or replacing a tired old run that's gone brittle, this is the cable that does the job once and does it right. Buy the spool, wire the boat the way it should be wired, and don't think about it again for a very long time.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e10 AWG (10-gauge) conductors, the common size for AC circuits in the 25 to 30 amp range on a mid-size boat\u003c\/li\u003e\n  \u003cli\u003eThree-conductor flat triplex in white, green, and black, matching the AC color code for neutral, ground, and hot\u003c\/li\u003e\n  \u003cli\u003eTinned copper strands, every strand plated against corrosion so terminations stay bright in salt air\u003c\/li\u003e\n  \u003cli\u003eFine stranded construction, not solid, so it flexes with a working hull instead of fracturing at vibration points\u003c\/li\u003e\n  \u003cli\u003eFlat PVC encasement lies flatter against stringers and in cable trays than round jacket, and secures more neatly\u003c\/li\u003e\n  \u003cli\u003eFull 100-foot spool, enough for a complete shore-power or inverter feed with margin to spare\u003c\/li\u003e\n  \u003cli\u003eUL and ABYC certified, so it passes muster with marine electrical inspectors and insurance surveyors\u003c\/li\u003e\n  \u003cli\u003ePVC insulation rated for wet and dry marine service in lockers, bilges, and cabin runs\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 10\/3 triplex marine wire used for?\u003c\/summary\u003e\n    \u003cp\u003eIt's a three-conductor flat cable most often used for AC circuits on a boat: shore-power branch circuits, inverter and charger feeds, cabin GFCI and outlet runs, and AC accessory loads.
