Sea-Dog 14/2 AWG Duplex Marine Wire 100ft | 8014222
Sea-Dog 14/2 AWG Duplex Marine Wire 100ft | 8014222 — Product description
If you're running a new DC accessory circuit and want it done right, Sea-Dog's 14/2 flat duplex is the wire you reach for. Two 14-gauge tinned copper conductors, red and yellow per the ABYC code, on a 100-foot spool. UL and ABYC certified, so it holds up in salt air and passes survey without a second look.
Sea-Dog's 14/2 flat duplex is the everyday boat wire you reach for when you're running a new accessory circuit and want it done right the first time. Two 14-gauge conductors, tinned copper, wrapped in PVC and bonded side by side in a flat jacket. You get a 100-foot spool, which is enough to cover most of the small-to-mid runs on a boat under 30 feet.
The tinned copper is the part that matters out here. Bare copper corrodes the moment salt air gets to it, and once a conductor starts to green up, resistance climbs and your accessory starts acting flaky. The tin plating on every strand slows that down for years. It's why UL and ABYC both list this wire, and why a surveyor won't blink at it.
The two conductors follow the ABYC DC color code: red is your positive, yellow is your negative. That takes the guesswork out of a run you're pulling through a dark bilge or up inside a console. Match red to red, yellow to the ground side, and you're done. The flat encasement lays nice and tight against a stringer or a conduit wall, so it doesn't bunch up the way round cable does.
Fourteen gauge is the sweet spot for a lot of DC work. Nav lights, bilge pumps, livewell pumps, small electronics, courtesy lighting. If you've got a longer run and your 16-gauge is dropping too much voltage by the time it reaches the load, stepping up to this 14/2 usually fixes it. For heavier loads or runs past what 14 can carry, move up to a 12 or 10 gauge instead.
One thing to know: this is two-conductor duplex, not triplex. There's no separate dedicated ground conductor in the jacket, so if your circuit needs a third wire, this isn't the one. For a straight positive-and-negative accessory run, though, it's exactly what you want. Seal your splices with adhesive-lined heat shrink and you'll get a clean, dry connection that lasts.

Frequently asked questions
What do the red and yellow colors mean?
They follow the ABYC DC color code. Red is your positive conductor and yellow is your negative. It keeps a run clear when you're wiring in a dark bilge or behind a console.
Is this duplex or triplex wire?
It's two-conductor duplex, positive and negative only. There's no separate dedicated ground conductor in the jacket. If your circuit needs a third wire, this isn't the one.
What can 14/2 wire handle on a boat?
It's a good fit for nav lights, bilge and livewell pumps, courtesy lighting, and small electronics. For heavier loads or runs longer than 14 gauge can carry, step up to a 12 or 10 gauge instead.
Why tinned copper instead of bare copper?
Bare copper corrodes fast in salt air, and corrosion raises resistance until your accessory gets flaky. The tin plating on every strand slows that down for years, which is why marine wire is tinned.
Is this wire UL and ABYC certified?
Yes. It carries both UL and ABYC listings, so it passes survey without a surveyor raising an eyebrow.
How much wire is on the spool?
You get 100 feet, which covers most small-to-mid accessory runs on a boat under 30 feet.
My 16-gauge run is dropping voltage. Will stepping up to 14/2 help?
Usually, yes. A heavier gauge carries the same load over a longer distance with less voltage drop, so moving from 16 to 14 gauge is a common fix for a run that's reaching too far.
