Sea-Dog 14 AWG Red Marine Primary Wire, 100 ft
Sea-Dog 14 AWG Red Marine Primary Wire, 100 ft — Product description
Sea-Dog's 14 AWG red primary wire gives you a 100-foot spool of stranded tinned-copper conductor for running 12-volt DC circuits on your boat. The tinned strands shrug off the corrosion that eats plain copper in salt air, and the red PVC jacket marks it as a positive lead at a glance.
Every boat runs on wire you can't see, and that hidden wiring is exactly where corrosion likes to start. Sea-Dog's 14 AWG red primary wire is built to hold up out there. You get 100 feet of single-conductor, stranded tinned-copper wire on a spool, wrapped in a red PVC jacket. It's the kind of wire you reach for when you're rigging up nav lights, cabin lights, gauges, a fish finder, or a small accessory circuit.
The tinning matters. Bare copper looks fine the day you install it, but salt air and humidity work their way into the strands over a season or two, and you end up chasing green corrosion and voltage drop. Tinned copper puts a thin coating on every strand, so it resists that corrosion far longer. That's why it's the standard for marine primary wire.
14 gauge is a good middle-of-the-road size. It'll carry the load for most low- to medium-draw DC circuits without overheating. Think running lights, courtesy lights, a bilge blower, instrument power, a stereo head unit. For higher-draw gear like a windlass, a thruster, or a big inverter, step up to heavier gauge. When you're not sure, size the wire to the amp draw and the run length, and give yourself some margin.
Red is the positive convention on a 12-volt DC system, so keep this spool for your positive runs and grab black for the grounds. The stranded construction stays flexible, which makes it easy to route behind panels and through tight chases. A couple of installer habits pay off. Seal every cut end with adhesive-lined heat-shrink so water can't wick up the strands. Use a ratchet crimper for connections that pass a real tug test. And run the wire in loom where it sees sun or chafe.
This is a 100-foot spool, enough for a full small-boat rewire or a good stash of wire for the projects that always come up. It's DC primary wire, not multi-conductor cable, so if you need a two- or three-wire run for a pump or an AC circuit, look at our duplex and triplex spools instead.

Frequently asked questions
What circuits is 14 AWG wire good for?
14 gauge handles most low- to medium-draw 12-volt DC circuits: running lights, courtesy and cabin lights, gauges, a bilge blower, a stereo head unit, small pumps. For heavy loads like a windlass, thruster, or large inverter, step up to a heavier gauge sized to the amp draw and run length.
Why tinned copper instead of plain copper?
Salt air and humidity corrode bare copper strands over time, and that shows up as green corrosion and voltage drop. Tinning coats every strand so it resists that corrosion far longer. It's the standard for marine wiring for exactly that reason.
Is this AC or DC wire?
This is single-conductor DC primary wire. Use it for 12-volt positive runs. For AC circuits, or anywhere you need two or three conductors in one jacket, use duplex or triplex marine cable instead.
Why is it red?
Red is the positive convention on a 12-volt DC system. Keep this spool for your positive leads and use black wire for the grounds, so anyone working on the boat later can trace the circuits.
How long is the spool?
It's a 100-foot spool. That's enough for a full rewire on a small boat or a solid stash of wire for the projects that always come up.
How do I keep the cut ends from corroding?
Seal every cut end with adhesive-lined heat-shrink so water can't wick up into the strands, and use a ratchet crimper so your connections pass a real tug test. Run the wire in loom where it sees sun or chafe.
