It's the positive-side heavy cable for high-amp DC runs, and it's UL listed and ABYC certified so it meets the standards a surveyor or insurer looks for.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis is Sea-Dog's 4\/0 AWG battery cable in red, wound on a 50-foot spool. It's the positive-side cable for heavy DC runs, the wire you reach for when you're feeding a big inverter, a bow thruster, a windlass, or running from the battery bank to a main bus on a larger boat.\u003c\/p\u003e\n\u003cp\u003eThe conductor is tinned copper, not bare copper, so it stands up to the salt air and damp that kills untinned wire in a few seasons. Every strand is coated, which keeps corrosion from creeping up under the insulation where you can't see it. That's the difference between a connection that holds for years and one you're re-doing next haul-out.\u003c\/p\u003e\n\u003cp\u003eIt ships without terminals, so you cut it to the exact length you need and crimp on your own lugs. It's UL listed and ABYC certified, so it meets the wiring standards that matter on the water. Pair it with the matching black 4\/0 for your negative run and you've got a clean, code-compliant DC feed.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e4\/0 AWG gauge carries high-amperage DC loads like inverters, windlasses, and bow thrusters\u003c\/li\u003e\n  \u003cli\u003eTinned copper conductor resists salt corrosion far longer than bare copper\u003c\/li\u003e\n  \u003cli\u003e50-foot spool lets you cut every run to length with no waste\u003c\/li\u003e\n  \u003cli\u003eRed jacket clearly marks it as the positive conductor\u003c\/li\u003e\n  \u003cli\u003eUL listed and ABYC certified to meet marine wiring standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Sea-Dog reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eDoes this cable come with terminals or lugs?\u003c\/summary\u003e\n    \u003cp\u003eNo. It ships as bare cable without terminals so you can cut it to length and crimp on the lugs your install needs.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhy tinned copper instead of plain copper?\u003c\/summary\u003e\n    \u003cp\u003eThe tin coating on every strand blocks the corrosion that salt air and moisture cause in bare copper.
