Two stranded, tinned copper conductors in a flat PVC jacket, red and black for easy polarity, built to UL and ABYC standards. It's the wire we reach for on lighting, pump, and instrument circuits, and the spool size means you cut clean runs with no splices buried in a bilge.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis is Sea-Dog's 14\/2 AWG flat duplex marine wire on a full 500-foot spool. Two 14-gauge stranded conductors, tinned copper, wrapped in a flat PVC jacket with a red and black lead so you never lose track of polarity halfway through a run. If you rig boats for a living or you're finally redoing the tired factory harness on your own hull, a spool this size means you stop buying wire by the foot and start pulling exactly the length each circuit needs.\u003c\/p\u003e\n\u003cp\u003eThe thing that matters most on a boat is the tinned copper. Bare copper looks fine the day you install it and then quietly turns green inside the insulation a season later, especially anywhere salt air gets to it. Every strand in this cable is tin-coated, so it shrugs off corrosion and keeps a clean connection at the lug for years. That's the whole reason marine wire costs more than the spool at the hardware store, and it's the reason we don't stock the hardware-store stuff.\u003c\/p\u003e\n\u003cp\u003eIt's built to UL and ABYC standards, which is the part your insurance surveyor cares about. The flat duplex construction lays nice and tight against a stringer or behind a panel, and it feeds through split loom cleanly. We run 14\/2 for cabin and courtesy lighting, nav and anchor light circuits on smaller boats, livewell and washdown pump feeds, instrument power, and plenty of the mid-load DC jobs on a 25 to 35 foot boat.\u003c\/p\u003e\n\u003cp\u003eThe red and black conductors take the guesswork out of polarity. Red is your positive, black is your negative, and because the jacket is flat and the two leads stay side by side, you can trace a circuit end to end without a meter. On a rewire that's a real time saver, and it makes the next person who opens that panel, maybe you in five years, actually able to follow what you did.\u003c\/p\u003e\n\u003cp\u003eNow, a word on sizing, because this is where people get into trouble. 14 gauge is good for about 15 amps, but amperage isn't the whole story on a boat. Voltage drop is. The longer the run, the more voltage you lose along the way, and a light that's dim or a pump that's sluggish is almost always an undersized wire on a long run, not a bad component. For a short hop to a courtesy light, 14\/2 is perfect. For a windlass, a thruster, or anything hungry way up in the bow, step up to a heavier gauge. When in doubt, measure the round-trip distance and check it against an ABYC drop chart. Or just ask us. We do this all day.\u003c\/p\u003e\n\u003cp\u003eA couple of install tips from the shop. A 500-foot spool is heavy and it likes to kink if you yank it, so set it on a spindle or a length of pipe and let it feed instead of flaking it onto the deck. Terminate with tinned ring or spade lugs and adhesive-lined heat shrink, not the cheap PVC crimps, and your connections will outlast the boat. Where the cable passes through a bulkhead or over an aluminum edge, use a grommet or a wrap of chafe tape so the jacket doesn't wear through with vibration.\u003c\/p\u003e\n\u003cp\u003eOne more note on the 500-foot count. It sounds like a lot until you start adding up a boat's DC circuits. Between lighting fore and aft, pumps in every compartment, and instrument runs to the helm, a mid-size boat eats wire fast. Having a full spool on the bench means you cut clean, continuous runs with no splices buried in a bilge, and splices buried in a bilge are exactly what you don't want on a boat.\u003c\/p\u003e\n\u003cp\u003eBottom line: it's honest, standards-built marine wire in a quantity that makes sense for a full rewire or a busy rigging bench. Buy the spool once, and you've got clean tinned duplex on hand for every 14-gauge circuit on the boat.\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 stranded conductors handle mid-load DC circuits like lighting, pumps, and instruments\u003c\/li\u003e\n  \u003cli\u003eTinned copper strands resist salt-air corrosion and hold a clean connection at the lug for years\u003c\/li\u003e\n  \u003cli\u003eFlat duplex PVC jacket lays tight against stringers and feeds cleanly through split loom\u003c\/li\u003e\n  \u003cli\u003eRed and black conductors make polarity obvious end to end, no meter needed\u003c\/li\u003e\n  \u003cli\u003e500-foot spool lets you pull continuous, splice-free runs for a full rewire\u003c\/li\u003e\n  \u003cli\u003eBuilt to UL and ABYC standards, the spec your surveyor and insurer want to see\u003c\/li\u003e\n  \u003cli\u003eRoughly 15-amp capacity suits courtesy lights, nav lights, livewell and washdown pumps, blowers, and instrument power\u003c\/li\u003e\n  \u003cli\u003eStranded construction flexes and shrugs off vibration fatigue better than solid 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\u003eWhat gauge is this and how many amps can it handle?\u003c\/summary\u003e\n    \u003cp\u003eIt's 14\/2 AWG, meaning two 14-gauge conductors. 14 gauge is good for roughly 15 amps, but on a boat voltage drop over the length of the run matters more than raw ampacity.
