Sea-Dog 10 AWG Black Primary Wire 100 ft | 8010012
Sea-Dog 10 AWG Black Primary Wire 100 ft | 8010012 — Product description
Sea-Dog's 10-gauge primary wire gives you 100 feet of tinned copper on a single spool, jacketed in black PVC. It's the stranded, corrosion-resistant wire you reach for when you're running a new circuit or replacing a tired old run below deck. Built for the wet, salty life your boat actually lives.
The Sea-Dog 10 Gauge Primary Wire is a 100-foot spool of single-conductor, stranded tinned copper wire wrapped in black PVC insulation. It's the kind of wire you keep on the shelf because sooner or later you're going to need it. New bilge pump. A pair of deck lights. That accessory circuit you've been meaning to run clean instead of the mess that's back there now.
Here's why the tinned copper matters. Bare copper corrodes fast in a marine environment. Salt air alone will start turning the strands green, and once corrosion creeps up under the insulation you lose conductivity and start chasing voltage drop you can't see. Every strand in this wire is tinned, so it shrugs off the moisture and salt that live on every boat. That's the whole reason marine wire costs more than the stuff at the hardware store, and it's worth it.
Ten gauge is your workhorse size for moderate DC loads. Think bilge pumps, livewell pumps, windlasses on smaller boats, banks of lights, and longer accessory runs where a thinner wire would drop too much voltage. The stranded construction keeps it flexible, so you can route it through tight chases and around bulkheads without fighting a stiff solid conductor.
The black jacket follows the common convention for negative and ground runs, so it's easy to keep your wiring readable when someone, maybe future you, opens the panel a few years from now. A single 100-foot spool covers most jobs on a small to mid-size boat with wire to spare. And because it's a single conductor, you pick exactly the color you need for each leg instead of being locked into a paired set.
One honest note. This is primary wire, a single conductor. If you need two conductors bonded together in one jacket, you want duplex wire instead. For single-leg runs where you're matching colors to a diagram, this is exactly right.
Key Features

Frequently asked questions
What can I use 10-gauge wire for?
Ten gauge is a good match for moderate DC loads, bilge and livewell pumps, banks of lights, small-boat windlasses, and longer accessory runs where thinner wire would drop too much voltage. For heavy loads or long high-current runs, step up to a larger gauge.
Why tinned copper instead of bare copper?
Bare copper corrodes quickly in salt air, and corrosion under the insulation quietly kills conductivity. Every strand here is tinned, so it holds up to the moisture and salt that live on every boat. That's why we don't sell bare-copper wire for marine work.
Is the black wire positive or negative?
By common convention black is used for negative and ground runs. Always follow your boat's wiring diagram and confirm polarity before you connect anything, since color is a convention, not a guarantee.
Is this a single wire or a two-conductor cable?
It's single-conductor primary wire, one insulated conductor on the spool. If you need two conductors bonded in one jacket, you want duplex wire instead.
How much wire is on the spool?
100 feet, enough to cover most wiring jobs on a small to mid-size boat with some to spare.
Can I run this in exposed or damp areas?
The PVC insulation and tinned copper are built for the damp, salty conditions on a boat. Support it properly, keep it away from heat sources and sharp edges, and it'll last.
