Sea-Dog 16 AWG Gray Primary Wire, 100 ft Spool
Sea-Dog 16 AWG Gray Primary Wire, 100 ft Spool — Product description
Sea-Dog's 16 AWG gray primary wire is a 100-foot spool of stranded tinned copper under gray PVC insulation. It's sized for the low-draw circuits on your boat, nav and courtesy lights, gauge feeds, LED and indicator runs. Tinned copper stands up to salt air and damp far better than bare wire, and stranded conductor flexes with the hull instead of cracking.
Sea-Dog's 16 AWG gray primary wire gives you a clean, single-conductor run for the low-draw circuits all over your boat. It's stranded tinned copper under gray PVC insulation, spooled at 100 feet, so you've got plenty on hand for a rewire or a stash in the shop for the next project.
Tinned copper is the part that matters out on the water. Bare copper corrodes, turns green at the ends, and eventually gives you voltage drop and flaky connections. The tin coating on every strand slows that down, which is why it's the standard for marine wiring you'll actually trust a few seasons in.
16 gauge is your low-current wire. Think nav lights, courtesy and cockpit lighting, gauge and sender feeds, LED strips, indicator and dash circuits, small electronics. It's not the wire for a bilge pump, a windlass, or a thruster. Those pull real amps and want heavier 10 or 12 gauge. Match the gauge to the load and the run length and you'll keep voltage drop where it belongs.
Gray is a handy color to keep on the spool. Run it wherever your wiring diagram or your own color code calls for a neutral conductor, and pair it with the other Sea-Dog colors so every circuit is easy to trace a year from now when you're back under the console chasing a fault.
The stranded conductor is the right call for a boat. Solid wire work-hardens and cracks where the hull flexes and pounds. Stranded flexes with it, routes easier through tight chases, and takes a crimp connector cleanly. Strip it, crimp on a heat-shrink connector, seal it up, and you've got a connection that shrugs off spray and bilge damp. And with 100 feet on the spool, there's enough here for a full nav-light run, a new gauge feed, a courtesy light circuit, or just topping off the wire drawer so you're not stuck mid-project.

Frequently asked questions
What is 16 AWG wire used for on a boat?
It's a low-draw wire. Use it for nav and courtesy lights, gauge and sender feeds, LED strips, indicator and dash circuits, and small electronics. It's not sized for high-current loads like bilge pumps, windlasses, or thrusters, which want heavier 10 or 12 gauge.
Is this tinned copper wire?
Yes. The conductor is stranded tinned copper under PVC insulation. The tin coating on every strand slows the corrosion that eats bare copper in salt air and damp, so your connections stay clean longer.
How much wire is on the spool?
100 feet. That's enough for a full nav-light run, a new gauge feed, a courtesy light circuit, or just topping off the wire drawer for the next project.
Can I use this for a bilge pump or windlass?
No. Those pull real amps and need heavier wire, usually 10 or 12 gauge. 16 gauge is for low-current circuits only. Always match the gauge to the load and the length of the run to keep voltage drop in check.
Does the gray color mean anything specific?
Gray is a neutral color. Run it wherever your wiring diagram or your own color code calls for it, and pair it with the other Sea-Dog colors so every circuit is easy to trace later.
Is the conductor stranded or solid?
Stranded. On a boat that's the right call, since solid wire work-hardens and cracks where the hull flexes and pounds. Stranded flexes with it, routes through tight chases easier, and takes a crimp connector cleanly.
