Sea-Dog 10 AWG Black Primary Wire 25 ft | 8010010
Sea-Dog 10 AWG Black Primary Wire 25 ft | 8010010 — Product description
This is Sea-Dog's 10 AWG black primary wire on a handy 25 foot spool. Stranded tinned copper under a black PVC jacket, sized for the higher-draw DC gear on your boat where 12 or 14 gauge just won't cut it.
When you're wiring a bilge pump, a windlass feed, or any accessory that pulls real current, gauge matters. This is Sea-Dog's 10 AWG single-conductor primary wire, and it's the size you reach for when 12 or 14 gauge would drop too much voltage over the run. The 25 foot spool is enough for a couple of accessory runs without leaving you with a giant reel of leftover wire, and it stores easy in a parts bin.
The conductor is stranded tinned copper. That tinning is the whole point on a boat. Bare copper wicks moisture up under the insulation and corrodes green from the inside out, and you don't see it until the connection goes high-resistance and the gear acts flaky. Tinned strands shrug that off, which is why it's the standard for marine DC work. The stranded build also flexes through tight chases and around bulkheads a lot easier than solid wire.
The jacket is black PVC. Black is the traditional color for the negative or ground side of a DC circuit, so running black for your grounds and a color for your positives keeps the loom readable when you or the next owner is chasing a fault two years from now. Keep the color-coding honest and future troubleshooting gets a lot easier.
A few install notes from experience. Cut ends wick water, so seal your terminations and don't leave a bare cut sitting in the bilge. Use a ratchet crimper and give every terminal a firm tug before you button it up. And loom or shrink any run that sees sun, because PVC will chalk and fade with enough UV exposure. Pair it with our Sea-Dog duplex and triplex spools when a job calls for multi-conductor runs. If you're not sure what gauge your load and run length need, give us a shout and we'll walk you through it.

Frequently asked questions
How many amps will this 10 gauge wire carry?
10 AWG handles a good bit more than 12 or 14 gauge, so it's the gauge for higher-draw gear. But ampacity drops as the run gets longer because of voltage drop. Size it off an ABYC ampacity chart for your actual run length and load rather than a single number, and when in doubt go one gauge heavier.
Why tinned copper instead of plain copper?
On a boat, bare copper wicks moisture up under the insulation and corrodes from the inside out, which quietly raises resistance until the gear acts up. The tin coating on each strand blocks that, which is why tinned wire is the standard for marine DC wiring.
Is this a single conductor or a two-wire cable?
It's single-conductor primary wire, one stranded conductor in a black jacket. For paired runs, look at our Sea-Dog duplex and triplex spools instead.
What's the black color for?
Black is the traditional color for the negative or ground side of a DC circuit. Running black for grounds and a color for positives keeps your loom readable when someone traces a fault later.
How much wire is on the spool?
25 feet. Enough for a couple of accessory runs without leaving you a giant reel of leftover wire.
Can I run this outside or in the sun?
You can, but PVC chalks and fades with enough UV. For exposed runs, loom it or run it through conduit so the jacket lasts. In the bilge, seal your cut ends so they don't wick water.
