It's the wire you reach for when a boat's DC runs need to last.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eSea-Dog's 14\/2 AWG safety duplex is the wire you reach for when a boat's DC runs need to last. It's flat tinned copper, two conductors under one jacket, and it comes on a full 500 foot spool. That's enough to wire out most of a mid-size boat and still have a working remnant left for the next project.\u003c\/p\u003e\n\u003cp\u003eSo what's the safety part? It's the color coding. The conductors run red and yellow, which makes them dead easy to trace months later when you're back under the console trying to remember which leg is which. No guessing, no ringing out every wire. On a busy install with nav lights, bilge pumps, and accessory circuits all sharing a chase, that color discipline saves real time. It's a small thing that pays off every single time you open that panel back up.\u003c\/p\u003e\n\u003cp\u003eEvery strand is tinned copper, and that matters more on the water than anywhere else. Bare copper wicks moisture and corrodes green from the cut end inward, and you won't see it happen until a circuit starts acting flaky. The tin coating seals each strand against salt air and humidity, so the wire you pull today still carries clean current years from now. The conductors are finely stranded too, so the cable stays flexible and takes a bend around a stringer without fighting you.\u003c\/p\u003e\n\u003cp\u003eThe flat encasement keeps the profile low, which helps when you're routing along a hull side or stacking runs in a conduit. Insulation is marine-grade PVC, and the cable carries both UL and ABYC certification. That's not a marketing checkbox. If you're wiring to survey standards or want an insurer to sign off without an argument, ABYC-listed tinned duplex is exactly what they're looking for.\u003c\/p\u003e\n\u003cp\u003eFourteen gauge is the sweet spot for a lot of marine circuits. Think 12V nav light runs on a 25 to 35 foot powerboat, cabin lighting, accessory feeds, small pumps. Keep an eye on distance though. On a longer run pulling real amperage, voltage drop starts to bite, so a 14 gauge leg carrying around 10 amps past 25 feet will lose enough voltage to matter on sensitive electronics. For those long hauls, step up a gauge. For the dozens of shorter runs on a typical boat, this is exactly the wire.\u003c\/p\u003e\n\u003cp\u003eA couple of things we've learned pulling this stuff. The jacket is stiff straight off a cold 500 foot spool, so let it sit in the sun for an hour or run a little pulling lube before you feed it through a tight bilge chase. Support the cable every 18 inches or so, especially near the engine room, because an unsupported 90 degree bend against a hard edge is where a PVC jacket eventually splits. And when you've cut what you need, keep the remnant on a reel stand rather than coiling it loose, or it'll kink.\u003c\/p\u003e\n\u003cp\u003eFuse it properly and terminate it right. A 15 amp blade fuse at the source protects a 14 gauge circuit well, and tinned ring terminals crimped onto tinned wire give you a connection that won't corrode apart at the lug. Untinned lugs on a salt water boat are a false economy. Pair good wire with good ends and the whole run stays healthy for years.\u003c\/p\u003e\n\u003cp\u003eOn sailboats, this duplex runs neatly alongside an existing wiring bundle at the mast base or along a bulkhead. Just add a wrap of chafe tape anywhere it crosses a line or a moving part. Bottom line, it's honest marine wire from a company that's been making deck and rigging hardware for boaters a long time. Buy the spool once, wire the boat right, and don't think about it again.\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 flat safety duplex, two conductors under one jacket for clean, low-profile runs\u003c\/li\u003e\n  \u003cli\u003eTinned copper stranding resists salt-air corrosion for long service life on the water\u003c\/li\u003e\n  \u003cli\u003eFinely stranded conductors stay flexible and bend around a stringer without fighting you\u003c\/li\u003e\n  \u003cli\u003eRed and yellow conductor color coding makes tracing circuits fast months down the road\u003c\/li\u003e\n  \u003cli\u003eMarine-grade PVC insulation stands up to bilge moisture and UV\u003c\/li\u003e\n  \u003cli\u003eUL and ABYC certified, wires to survey and insurance standards\u003c\/li\u003e\n  \u003cli\u003e500 foot spool covers most of a mid-size boat with remnant to spare\u003c\/li\u003e\n  \u003cli\u003eSized right for 12V nav lights, cabin lighting, small pumps, 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 is 14\/2 AWG safety duplex used for?\u003c\/summary\u003e\n    \u003cp\u003eIt's a general-purpose 12V DC marine cable.
