Sea-Dog 4/0 AWG Tinned Copper Battery Cable, Black, 50 ft Spool
Sea-Dog 4/0 AWG Tinned Copper Battery Cable, Black, 50 ft Spool — Product description
Heavy-gauge 4/0 tinned copper battery cable from Sea-Dog, on a full 50-foot spool. The black jacket flags your negative and ground runs, and it ships without terminals so you cut each length to fit. UL and ABYC certified for high-current jobs like inverters, windlasses, and main battery banks.
When you're wiring a big house bank, an inverter, a windlass, or a bow thruster, you need cable that moves serious current without heating up. This Sea-Dog 4/0 AWG battery cable does exactly that. It's tinned copper, so every strand is coated to fight the corrosion that plain copper picks up in a damp, salty bilge. The black jacket marks it as your negative or ground run.
You get a full 50-foot spool, and it ships without terminals so you can cut each run to the exact length you need and crimp on your own lugs. That's how the pros do it. No wasted cable, no pre-made lengths that don't fit your layout.
It's UL and ABYC certified, which matters if you care about doing the job right and passing a survey. 4/0 is heavy gauge, rated for high-amperage cranking and inverter runs where voltage drop is the enemy. Wire it in once, and you won't think about it again.

Frequently asked questions
Does this cable come with terminals or lugs?
No. It ships as a bare 50-foot spool without terminals, so you cut each run to length and crimp your own lugs. That lets you wire the exact runs your boat needs with no wasted cable.
Why is the jacket black?
Black marks this as a negative or ground conductor. Keep your positive runs on red cable so polarity stays clear at a glance during install and future service.
Is the copper tinned?
Yes. Every copper strand is tinned, which coats it against corrosion. In a marine environment bare copper wicks moisture and corrodes, so ABYC installs call for tinned cable that holds up far longer.
What is 4/0 cable used for?
4/0 (four-aught) is heavy-gauge cable for high-current runs: main battery cables, inverters, windlasses, bow thrusters, and large engine cranking circuits where you can't afford voltage drop.
Is it certified for marine use?
Yes. It's UL and ABYC certified, so it meets recognized standards for marine electrical wiring and will pass a surveyor's check.
