It's finely stranded and built to meet UL and ABYC standards, so it stands up to salt air and stays low-resistance for the DC grounding and bonding runs on your boat.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis is Sea-Dog's 8-gauge marine primary wire, sold as a full 100-foot spool in green. It's tinned copper, finely stranded, and built to meet UL and ABYC standards, so it holds up to the damp, salty life a boat's wiring actually lives. If you're pulling a new DC circuit or replacing tired old wire that's gone dark and brittle at the ends, this is the kind of conductor you want behind the panel and down in the bilge.\u003c\/p\u003e\n\u003cp\u003eThe big reason to spend on marine wire instead of the automotive stuff at the hardware store is the tinning. Every copper strand is coated in tin, which keeps moisture and salt air from corroding the conductor over time. Bare copper looks fine on day one, but a few seasons in a wet locker and it starts turning green and going high-resistance right where you can't see it. Tinned copper shrugs that off. There's no exotic maintenance to it either, you just install it and forget it. It's the difference between wiring you do once and wiring you keep chasing.\u003c\/p\u003e\n\u003cp\u003eThe green jacket matters too. Under ABYC color conventions, green is the standard color for grounding and bonding conductors, so keeping a spool on hand lets you wire your bonding system and safety grounds in the right color instead of guessing later. Consistent color coding is what makes a panel readable to the next person who opens it up, whether that's a surveyor, a yard tech, or you three years from now.\u003c\/p\u003e\n\u003cp\u003eAt 8 AWG, this wire suits medium-draw DC circuits. Think bilge pump feeds, windlass and winch grounds, accessory panels, and mid-size equipment runs. How many amps 8-gauge can carry depends on the temperature rating and how tightly it's bundled, so always size the circuit against the ABYC ampacity table rather than a rule of thumb. And remember voltage drop. On a 12-volt boat, a long run at real current can drop enough voltage to matter, so keep runs as short as practical or step up a gauge when the distance gets away from you. Whatever the circuit, fuse or breaker it at the wire's rating and not just the load, so the conductor is always protected before it can overheat.\u003c\/p\u003e\n\u003cp\u003eThe conductor is finely stranded, not solid, which is exactly what you want on a boat. Stranded wire flexes around stringers, bulkheads, and into tight engine spaces without work-hardening and cracking the way solid wire does. Terminate it with proper marine crimp terminals and the right die, add adhesive-lined heat shrink over the crimp, and you've got a connection that'll take vibration and spray for years. Leave a little slack at each end so future service is easy, because you will be back in there eventually.\u003c\/p\u003e\n\u003cp\u003eA couple of honest notes. This is single-conductor primary wire, not a two- or three-wire duplex or triplex cable, so you're buying one color to pair with your positive and other conductors as your layout needs. It also isn't a pre-made battery cable with lugs attached. You cut and terminate it to your run. And if any of it runs somewhere exposed to sunlight, route it through split loom or conduit. Insulation takes a beating from UV over a few years, and a little protection keeps it flexible.\u003c\/p\u003e\n\u003cp\u003eThe 100-foot spool is the practical buy for a rewire or a bigger project, where you'll cut several grounding and bonding runs from one roll and still have wire left for the next job. Seal or terminate any cut ends you're not using right away so they don't oxidize in storage. It's plain, well-made wire that does its job and stays out of trouble, which is all you really want out of the stuff hiding behind your helm.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e8 AWG stranded conductor sized for medium-draw DC circuits like pump feeds, panel grounds, and mid-size equipment runs\u003c\/li\u003e\n  \u003cli\u003eTinned copper core resists salt-air corrosion, so connections stay low-resistance season after season\u003c\/li\u003e\n  \u003cli\u003eGreen insulation follows ABYC color conventions for grounding and bonding conductors, keeping your wiring readable\u003c\/li\u003e\n  \u003cli\u003eFinely stranded construction flexes into tight engine spaces and around bulkheads without cracking\u003c\/li\u003e\n  \u003cli\u003eBuilt to meet UL and ABYC standards for marine electrical systems, so it passes survey and inspection\u003c\/li\u003e\n  \u003cli\u003eFull 100-foot spool gives you enough wire for a complete rewire or several grounding runs from one roll\u003c\/li\u003e\n  \u003cli\u003eSingle-conductor primary wire you cut and terminate to your own run length\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\u003eHow many amps can 8 AWG marine wire carry?\u003c\/summary\u003e\n    \u003cp\u003eIt depends on the insulation temperature rating and how many conductors are bundled together, so there's no single number.
