Ancor White Triplex Cable - 12/3 AWG - Round - 250'

The Ancor White Triplex Cable - 12/3 AWG - Round - 250' is a marine-grade electrical solution purpose-built for boats, sailboats, and watercraft requiring reliable power distribution and control circuits. After years on the water, any experienced boater knows that saltwater, moisture, and vibration demand wiring that won't fail when you need it most. This 250-foot spool provides the length and capacity necessary for complete vessel rewiring or major circuit upgrades, whether you're upgrading a center console, cruiser, or sailboat electrical system.

Built to ABYC (American Boat and Yacht Council) standards, the Ancor triplex cable features three individually color-coded marine-grade primary conductors—white, green, and black—twisted together in a single unified round profile and enclosed within a white UV-resistant common jacket. The 12 AWG gauge delivers the amperage capacity needed for lighting circuits, bilge pumps, and other secondary systems without voltage drop across moderate distances. The round design simplifies installation through tight spaces and conduit, while the UV-resistant white jacket protects against sun damage and extends service life in both covered and open-deck applications.

Boaters retrofitting aging electrical systems or building custom wiring harnesses will appreciate the full 250-foot length, which eliminates the need for multiple spools and reduces splices that invite corrosion. The correct color coding—white (neutral/ground), green (ground), and black (hot)—ensures compliance with marine electrical codes and eliminates confusion during installation and future troubleshooting. This cable is ideal for both freshwater and saltwater vessels and integrates seamlessly with Ancor tinned-copper components and marine-grade terminals. Calculate your run length before ordering; the 250-foot spool covers most single systems or partial-vessel rewires with minimal waste.
