Sea-Dog 16 AWG Yellow Marine Primary Wire | 8016032
Sea-Dog 16 AWG Yellow Marine Primary Wire | 8016032 — Product description
This is Sea-Dog's 16 gauge single-conductor primary wire in yellow, wound on a 100 foot spool. Tinned copper under a PVC jacket, so it fights corrosion the way marine wire should. It's the right size for low-draw runs, think nav lights, gauge feeds, panel indicators, and small accessories.
Sea-Dog's 16 AWG primary wire is the thin, flexible workhorse you reach for when a circuit doesn't pull much current. It's a single stranded conductor of tinned copper, wrapped in a yellow PVC jacket, and it ships on a 100 foot spool so you've got plenty on hand for a rewire or a season of small projects.
Sixteen gauge sits at the light end of the scale. That makes it the right call for low-draw runs over short distances. Think navigation and courtesy lights, gauge and sender feeds, panel indicators, LED accents, and other small accessories that sip amps rather than gulp them. It's not the wire for a bilge pump on a long run, a windlass, or a thruster. Those want heavier copper. When you're not sure, size up rather than down and keep the run as short as the layout allows.
The tinned copper is what earns this wire its spot on a boat. Every strand carries a thin coat of tin, so when moisture works its way into a cut end or a crimp, the copper underneath doesn't turn green and go brittle the way bare copper does. Salt air, bilge damp, a splash over the gunwale, tinned wire shrugs it off far longer. And the stranded construction keeps it flexible enough to route around bulkheads and through tight chases without fighting you.
A few install notes. The spool holds a gentle curve, so pull off a little more than you need and let it relax before you cut. Seal both ends, because an open cut on tinned wire will still wick water up the strands over time. A quality adhesive-lined heat-shrink connector at every termination keeps the joint dry and takes the strain off the crimp. And that yellow jacket is there to help you color-code, so you can trace a run months later without pulling half the panels apart.
Running a full harness? We stock this same primary wire in other gauges and colors, plus Sea-Dog duplex and triplex spools when you need two or three conductors in one jacket. Tell us what you're wiring and we'll point you at the right gauge for the load.

Frequently asked questions
What is 16 gauge primary wire good for?
It's sized for low-draw circuits over short runs. Navigation and courtesy lights, gauge and sender feeds, panel indicators, LED accents, and small accessories are all good uses. Save the heavier gauges for pumps, windlasses, and anything that draws a lot of current.
Is the copper tinned?
Yes. Every strand carries a thin coat of tin, which is what keeps the copper from corroding when moisture reaches a cut end or a crimp. That's the difference between marine-grade wire and the bare copper automotive stuff.
How much wire is on the spool?
You get 100 feet on the spool. Enough for a full rewire of small circuits or a whole season of odd jobs.
Is this a single conductor or a two-wire cable?
It's single-conductor primary wire, one insulated conductor. For a complete circuit you'll run a separate return, or step up to a Sea-Dog duplex spool that carries two conductors in one jacket.
Can I wire a bilge pump with it?
Depends on the pump's draw and how long the run is, but 16 gauge is on the light side for most pumps. If in doubt, size up to a heavier gauge and keep the run short. Undersized wire runs warm and drops voltage.
Is this for 12-volt DC or household AC?
It's primary wire for low-voltage DC circuits, the 12-volt systems you find on most boats. It isn't AC branch wiring for shore-power circuits.
