Sea-Dog 16/3 Triplex Marine Wire 100ft, Tinned Copper — Product description

Sea-Dog's 16/3 triplex wire gives you three tinned-copper conductors in one flat, easy-to-run jacket. It's a 100-foot roll of 16 AWG, color-coded white, green, and black, and it's built to UL and ABYC standards so it holds up to salt air and vibration for the long haul.

This is the wire you reach for when a job needs three conductors run together and you don't want to fight three separate spools. Sea-Dog's 16/3 triplex bundles three 16-gauge conductors under one flat PVC jacket, color-coded white, green, and black so you always know which leg is which. The flat encasement lays clean along a stringer or through a chase, and it staples down without the twist you get from loose parallel runs. One pull, three legs, done.

Every strand is tinned copper. That tin coating is what separates real marine wire from the automotive stuff. Bare copper wicks moisture and turns green at the ends, and once corrosion creeps up under the insulation you lose conductivity and start chasing voltage drop you can't see. Tinned strands shrug off the salt air, so a connection you crimp today still reads clean in five years. The conductors are stranded too, not solid, so they flex around bends and take vibration without work-hardening and cracking.

Sixteen gauge is the sweet spot for a lot of low-current three-wire runs. Think nav light circuits that need a hot, a ground, and a second feed, three-wire bilge setups, accessory lighting, or any spot where you'd rather pull one tidy jacket than three. The white, green, and black coloring keeps your wiring diagram honest, which matters when the next person opens that panel and has to figure out what you did.

The whole thing is a 100-foot roll, enough to wire a small boat's worth of accessory circuits or keep a good length on the shelf for the next project. It carries both UL and ABYC ratings, so it meets the recognized standard for boat wiring and it'll pass a survey. Strip it, crimp on a heat-shrink connector, and you're done. It's honest wire that does exactly what marine-grade wire is supposed to do.

Key Features

  • 16 AWG, three-conductor triplex construction bundles three legs under one flat jacket for clean, single-pull runs
  • Tinned copper conductors resist corrosion and voltage-drop creep in salt air far better than bare copper
  • Stranded conductors flex easily for routing through tight chases and around bends
  • Color-coded white, green, and black insulation keeps three-wire circuits easy to trace and service
  • PVC insulation and flat encasement lay flat and staple down without twisting
  • 100-foot roll covers most accessory and lighting circuits with length to spare
  • UL and ABYC rated to meet recognized marine wiring standards

Frequently asked questions

What does 16/3 mean on this wire?

It means 16 AWG gauge with three separate conductors bundled together. Each of the three legs is a 16-gauge stranded conductor, color-coded white, green, and black under one flat jacket.

Why tinned copper instead of plain copper?

The tin coating on each strand protects the copper from the moisture and salt air on a boat. Bare copper corrodes at exposed ends and under insulation, which raises resistance and causes hidden voltage drop. Tinned wire keeps a clean connection for years.

Is this wire ABYC compliant?

Yes. It carries both UL and ABYC ratings, so it meets the recognized standards for marine wiring and will pass a survey.

What is triplex or flat encasement wire used for?

Triplex bundles three conductors under one flat jacket so you can run three legs as a single tidy pull. It's handy for nav light circuits, three-wire bilge setups, and accessory runs that need a hot, a ground, and a second feed.

How long is the roll?

This is a 100-foot roll, enough to wire a small boat's accessory and lighting circuits with length left over for the shelf.
