Sea-Dog 14 AWG Tinned Copper Wire, Black 100 ft
Sea-Dog 14 AWG Tinned Copper Wire, Black 100 ft — Product description
Sea-Dog's 14-gauge primary wire is a single-conductor, stranded tinned copper wire on a 100-foot black spool. The tinned strands shrug off the corrosion salt air brings, and the stranded core flexes with a boat that's always moving. It's your go-to for 12-volt accessory and ground runs.
Sea-Dog's 14-gauge primary wire is the stuff you reach for when you're running a new accessory circuit and you want it done right. It's a single-conductor, stranded wire with a tinned copper core and a black PVC jacket, wound on a 100-foot spool. Tinned copper is the detail that matters out on the water. The tin coating over every strand fights off the corrosion that plain copper gives in to once salt air and bilge moisture get to it.
Why stranded instead of solid? Because boats move. They pound through chop, they flex, they vibrate all day. Stranded conductor takes that flexing without the strands work-hardening and snapping the way a solid core eventually would. It's also just easier to route through tight chases and around bulkheads. This is the wire for 12-volt accessory runs: nav lights, courtesy lighting, a bilge pump, electronics, a stereo, whatever low-to-moderate-draw gear you're wiring in.
The black jacket makes it your go-to for negative and ground returns, or the negative leg of a two-color run. Pair a spool of black with a spool of red and you've got a clean color scheme the next person to open the panel will actually understand. 100 feet is enough to wire up most of a small-to-mid boat's accessory circuits without running to the store mid-project.
A few honest notes. This is primary wire, so it's a single insulated conductor, not a sheathed two or three-wire cable. If you need a duplex or triplex run inside one jacket, that's a different product. And PVC insulation is happy in the usual spots, but keep it away from constant high heat like a manifold or exhaust. Give yourself a little slack at every connection, use adhesive-lined heat shrink on your terminals, and this wire will outlast most of what you connect it to.

Frequently asked questions
Is this single-conductor primary wire or a multi-wire cable?
It's single-conductor primary wire, one tinned copper conductor in a PVC jacket. If you need two or three conductors inside one sheath, you'd want a duplex or triplex cable instead.
Why tinned copper instead of bare copper?
The tin coating on each strand slows the corrosion that salt air and bilge moisture cause in bare copper. On a boat that means connections that stay bright and conductive for years instead of going green.
What are the downsides of tinned copper wire?
Honestly, the main one is cost. Tinned copper runs a little more than bare copper because of the extra plating step. Out on the water that trade is worth it, the corrosion resistance pays for itself in fewer failed connections.
What are the downsides of stranded wire?
Stranded is a touch more work to terminate cleanly, and a loose strand can cause a short if you're sloppy at a connection. But for anything that moves or vibrates, like a boat, stranded is the right call over solid. Just crimp clean terminals and you're set.
What circuits is 14 gauge good for?
14 AWG is a common size for accessory and lighting circuits: nav lights, courtesy lights, a bilge pump, electronics, a stereo. For higher-draw gear or long runs, step up to a heavier gauge to keep voltage drop in check.
How much wire is on the spool?
100 feet, wound on a single spool of black wire.
