Sea Dog 4/0 AWG Tinned Battery Cable, Yellow, 100 ft Spool
Sea Dog 4/0 AWG Tinned Battery Cable, Yellow, 100 ft Spool — Product description
This is Sea Dog's 4/0 AWG battery cable in yellow, sold as a 100-foot spool with no terminals attached so you cut it to your exact runs. The conductor is tinned copper, which is what you want on a boat where salt air eats bare copper alive. It's UL listed and ABYC certified for marine DC work.
If you're wiring up a battery bank, a big inverter, or a bow thruster, 4/0 gauge is the cable that carries serious current without heating up. This is Sea Dog's yellow 4/0 AWG cable on a full 100-foot spool. It ships without terminals, so you measure your runs, cut, and crimp your own lugs to fit the job.
The conductor is tinned copper. That tinning matters more than folks think. Bare copper corrodes fast in a marine environment, and once corrosion creeps up under the insulation you lose conductivity and gain heat. Tinned strands hold up to salt air and bilge moisture for years.
Yellow is the common color for negative runs, so it's easy to keep your polarity straight at the panel. The cable is UL listed and ABYC certified, which is what surveyors and insurers want to see on a boat's DC system. Buy the length you need and terminate it yourself for a clean install that'll pass inspection.
Key Features
- 4/0 AWG gauge: heavy conductor sized for high-current runs like inverters, thrusters, and battery banks

Frequently asked questions
What gauge is this cable?
It's 4/0 AWG, one of the heaviest common battery-cable sizes. It's sized for high-current DC runs like inverters, windlasses, bow thrusters, and main battery leads.
Does it come with terminals or lugs?
No. It ships as bare cable without terminals, so you cut it to length and crimp your own lugs to match your setup. That's the standard way to wire custom runs.
Why tinned copper instead of bare copper?
Tinned strands resist corrosion from salt air and moisture. On a boat, bare copper corrodes under the insulation over time, which robs you of conductivity and creates heat. Tinning is the marine standard for that reason.
Is the yellow cable positive or negative?
Yellow is typically used for negative, or ground, runs in marine DC wiring. Using yellow for negative keeps your polarity clear at the panel and helps anyone servicing the system later.
Is it certified for marine use?
Yes. It's UL listed and ABYC certified, which is what surveyors and insurers expect to see on a boat's DC electrical system.
