Sea-Dog 16 AWG Red Primary Wire 500ft | 8016027
Sea-Dog 16 AWG Red Primary Wire 500ft | 8016027 — Product description
This is Sea-Dog's 16-gauge red primary wire on a full 500-foot spool. Stranded tinned copper with PVC insulation, UL and ABYC certified. It's the everyday hookup wire for nav lights, pumps, and the dozen small DC accessories that live on a boat.
This is Sea-Dog's 16-gauge single-conductor primary wire, red, on a full 500-foot spool. It's the everyday hookup wire you reach for when you're running power to nav lights, a bilge float switch, courtesy lighting, a stereo, or any of the dozen small DC accessories that live on a boat. Sixteen gauge handles the low-amperage runs where 12 or 10 gauge would just be overkill.
The conductor is stranded tinned copper. That tinning matters more on a boat than just about anywhere else. Bare copper corrodes fast in salt air, wicks moisture up under the insulation, and turns green and brittle at the worst possible spot behind a panel. The tin coating on every strand slows that down for years. And it's stranded, not solid, so it flexes as the hull works and takes a terminal crimp cleanly.
Insulation is PVC, color-coded red so you can keep your positive runs straight when you're staring at a bundle behind the helm. The wire carries both UL and ABYC certification, which is what a surveyor or an insurance inspector wants to see on marine DC wiring. If you're rewiring to code, this is the stuff that passes.
Five hundred feet is a working spool. It's enough to rewire a mid-size boat's accessory circuits and still have plenty left on the reel for the next project. Buy it once, pull off what each job needs, and stop making parts-store runs for three feet of wire at a time.
One honest note. This is single-conductor primary wire, not duplex or triplex. If you need paired positive and negative in one jacket for a longer run, that's a different Sea-Dog part. And red is red. If you want to color-code your grounds or a second circuit, grab a spool in another color too. For straightforward positive runs on 12-volt systems, though, a 500-foot spool of this red 16-gauge is about as useful as marine wire gets.
Key Features

Frequently asked questions
What's 16-gauge wire good for on a boat?
It's the right size for low-amperage DC circuits: nav lights, courtesy lighting, a bilge float switch, a stereo, small accessory runs. For higher-draw loads you'd step up to 12 or 10 gauge, but for the small stuff 16 gauge is exactly right.
Why tinned copper instead of plain copper?
Salt air eats bare copper. It corrodes, wicks moisture under the insulation, and goes green and brittle right where you can't see it. The tin coating on every strand slows all of that down, which is why tinned wire is the standard for boats.
Is this wire actually marine rated?
Yes. It carries both UL and ABYC certification, so it meets the marine DC wiring standard a surveyor or insurance inspector looks for. If you're rewiring to code, this passes.
Is this a single wire or a two-conductor cable?
Single conductor. It's primary wire, one red conductor in PVC insulation. If you need paired positive and negative in one jacket, that's duplex wire, a different Sea-Dog part.
How much wire is on the spool?
500 feet. That's a working spool, enough to rewire a mid-size boat's accessory circuits and keep plenty on the reel for the next job.
Can I use the red wire for a ground?
You can, but red is conventionally the positive color, and mixing it up makes troubleshooting harder later. For grounds or a second circuit, grab a spool in another color so your wiring stays easy to read.
