Sea-Dog 18 AWG Tinned Copper Primary Wire, 100ft Gray — Product description

Need a reliable run of primary wire for your boat? This Sea-Dog 18 AWG tinned copper wire comes on a 100-foot gray spool, ready for nav lights, gauges, and small accessory circuits. The tinned strands stand up to the damp, salty conditions that turn bare copper green. Gray coloring keeps your circuits easy to trace behind the dash.

Anyone who's chased down a corroded connection behind a console knows why tinned wire matters. This Sea-Dog primary wire uses tinned copper strands, so the whole conductor resists the green corrosion that eats plain copper in a marine environment. It's 18 gauge, which is the sweet spot for low-current runs like nav lights, instrument gauges, switch panels, and small accessories.

You get 100 feet on a single spool, enough to wire up a few circuits or keep a roll in the rigging kit for the next project. The stranded conductor stays flexible, so it's easy to route through tight chases and around bulkheads without fighting stiff solid wire. The gray jacket gives you a dedicated color for circuit tracing, which makes troubleshooting a lot less painful down the road.

We rig up boats every day, and having the right gauge in the right color on hand saves real time. Keep this spool in the shop and you're ready for the small wiring jobs that always come up.

Frequently asked questions

What is 18 AWG primary wire used for?

18 gauge wire suits low-current circuits, think nav lights, instrument gauges, switch wiring, and small accessories. For higher-draw loads like windlasses or bilge pumps, you'll want a heavier gauge.

Why tinned copper instead of bare copper?

Every strand is coated in tin, so the conductor resists the green corrosion that creeps into bare copper out on the water. It holds up far better in a damp, salty environment and keeps your connections solid.

How much wire is on the spool?

You get a full 100-foot spool of gray wire, enough to handle several circuits or keep a roll on hand for future projects.

Is the conductor solid or stranded?

It's stranded, which keeps the wire flexible and easy to route through tight spaces and around bulkheads without the stiffness of solid-core wire.
