Sea-Dog 16/2 AWG Duplex Marine Wire 100 ft | 8016202
Sea-Dog 16/2 AWG Duplex Marine Wire 100 ft | 8016202 — Product description
Sea-Dog's 16/2 duplex wire is 100 feet of two-conductor, tinned-copper cable in a flat PVC jacket. Black and red conductors, UL and ABYC certified, sized for the lower-draw DC circuits all over your boat, from nav lights to cabin fans.
Sea-Dog's 16/2 duplex wire gives you 100 feet of two-conductor, tinned-copper cable in a flat PVC jacket. Two 16-gauge conductors run side by side under one encasement, one black and one red, so you always know which leg is which when you're crimping in a dark bilge.
Sixteen-gauge duplex is the workhorse for the lower-draw DC circuits all over a boat. Nav and anchor lights, courtesy lighting, cabin fans, gauges, small accessory runs. Anywhere you're carrying a modest load and want a clean two-wire run without pulling two separate primary wires and taping them together. The 100-foot spool covers a whole boat's worth of small circuits with plenty to spare.
The reason you buy tinned copper instead of bare copper comes down to salt. Every strand in this wire is tin-plated, so salt air and bilge moisture don't creep in and turn the copper green. Bare copper corrodes from the cut ends inward, and once a conductor starts going, your voltage drop climbs and your lights dim. Tinned copper stays bright and keeps its conductivity for years, which is exactly why the marine standards call for it.
That's the other thing worth knowing here. This wire is UL listed and built to ABYC standards, so it'll pass survey and it's the right call for any circuit you want done properly. The flat encasement lies neat along a stringer or inside a raceway, zip-ties down clean, and won't roll around like round cable.
One honest note on sizing. Sixteen-gauge is right for lower-current circuits over short to moderate runs. If you're feeding a windlass, a big pump, or anything with real amperage, or you've got a long run to the bow, step up to a heavier gauge to keep voltage drop in check. Not sure what you need? We're happy to help you size it against your load and run length.
Key Features
- 16 AWG two-conductor duplex, sized for lower-draw DC circuits like nav lights, cabin fans, and accessory runs
- Tinned copper conductors resist salt corrosion and hold conductivity for years, where bare copper turns green and fails
- PVC insulation with a flat encasement lies neat in a raceway or along a stringer and zip-ties down clean
- Black and red conductors keep polarity obvious at every crimp
- 100-foot length covers a full boat's worth of small circuits with room to spare
- UL listed and ABYC certified so it passes survey and meets marine wiring standards

Frequently asked questions
What gauge and how many conductors is this wire?
It's 16 AWG with two conductors, a duplex cable. Both conductors run side by side under one flat PVC jacket.
Is the copper tinned?
Yes. Every strand is tin-plated copper, which is what keeps salt air and bilge moisture from corroding the conductor and dropping your voltage over time.
What circuits is 16-gauge wire good for?
Lower-draw DC circuits: nav and anchor lights, courtesy lighting, cabin fans, gauges, and small accessory runs. For heavier loads like a windlass or a big pump, or for long runs, step up to a heavier gauge to keep voltage drop in check.
Is it certified for marine use?
It's UL listed and built to ABYC standards, so it's the right wire for a boat and it'll pass survey.
What do the black and red conductors mean?
The two colors let you keep polarity straight from end to end. Wire it to match your circuit, red conventionally to positive and black to the return, and keep it consistent across the whole run.
How much wire is on the spool?
100 feet, enough to cover a whole boat's worth of small two-wire circuits with plenty left over.
