Sea-Dog 16 AWG Light Blue Marine Primary Wire 100ft
Sea-Dog 16 AWG Light Blue Marine Primary Wire 100ft — Product description
Sea-Dog's 16 AWG primary wire in light blue, on a 100 foot spool. Single-conductor stranded tinned copper with PVC insulation, sized for the low-draw DC circuits on a boat: nav and courtesy lights, LED strips, and gauge feeds. Tinning fights corrosion so your connections stay clean season after season.
This is Sea-Dog's 16 AWG primary wire in light blue, wound on a 100 foot spool. It's single-conductor stranded wire built for the low-draw DC circuits that run all over a boat. Think nav and anchor lights, courtesy lighting, LED strips, and the feeds to your gauges and senders. If a circuit doesn't pull much current, this is the wire that carries it.
The conductor is stranded tinned copper, and that tinning matters on the water. Bare copper starts to green and corrode the moment salt air and humidity get to it, and once a strand corrodes you lose conductivity and start chasing voltage drop. The tin coating slows that down, so a connection you crimp today still reads clean a few seasons from now. Stranded construction also flexes. You can pull it through conduit, snake it behind a panel, and bend it around a tight corner without a solid conductor work-hardening and cracking on you.
Around the copper is a PVC insulation jacket that shrugs off the usual abuse in a wiring run. Abrasion where the wire passes a bulkhead. The odd splash of oil or fuel. General moisture. The light blue color isn't tied to any fixed circuit standard here. It's there so you can color-code your own system and actually trace a run months later when you're back under the dash trying to remember what goes where.
A word on sizing, because it matters. 16 AWG is a small-gauge wire meant for light loads. It's great for lighting and instrumentation, but it's not the wire for a bilge pump, a windlass, a thruster, or anything else that pulls real amperage. Those loads need a heavier gauge and shorter runs to keep voltage drop in check. Match the gauge to the load and you'll have a clean, reliable circuit. Undersize it and you'll cook the insulation. So keep this one for the low-draw stuff, where it does its job quietly for years.
The 100 foot spool is a practical length. Enough to handle a full lighting rewire on a small boat, or to keep a color on the shelf so you've always got some when the next project shows up. And it will.

Frequently asked questions
What should I use 16 AWG primary wire for?
Low-draw DC circuits: navigation and anchor lights, courtesy and cabin lighting, LED strips, and the feeds to your gauges and senders. It's a small gauge meant for light loads.
Can I run a bilge pump or windlass on this wire?
No. Those are high-amperage loads that need a heavier gauge and shorter runs to control voltage drop. Keep 16 AWG for lighting and instrumentation, and size up for anything that pulls real current.
Is the conductor tinned?
Yes. It's stranded tinned copper. The tin coating slows the corrosion that bare copper suffers in salt air and humidity, so your connections hold up over time.
How much wire is on the spool?
100 feet, all one continuous light blue conductor.
Why stranded instead of solid wire?
Stranding flexes. On a boat that vibrates and where you're pulling wire through tight spaces, stranded conductor bends around corners and stands up to movement without work-hardening and cracking the way solid wire can.
Does the light blue color mean a specific circuit?
Not here. The color is for your own wiring scheme, so pick a color per circuit type and keep it consistent. That's what makes tracing a run easy later.
