Ancor Brown 18 AWG Tinned Copper Wire - 100'

Ancor Brown 18 AWG Tinned Copper Wire in 100-foot spools is purpose-built for marine electrical systems where corrosion resistance and long-term reliability are non-negotiable. Whether running power circuits on a fishing vessel, installing navigation equipment, or wiring auxiliary systems on offshore platforms, this marine-grade wire exceeds UL 1426, ABYC (American Boat and Yacht Council), and U.S. Coast Guard standards for charter vessel wiring (CFR Title 46). The tinned copper construction prevents oxidation in salt-air environments where bare copper would fail within months.

The 18 AWG gauge handles up to 16 amps at 12-volt systems—sufficient for running cabin lighting, bilge pumps, fish finders, and autopilot systems without voltage drop over moderate distances. Premium vinyl insulation rated at 600V with a 105°C dry/75°C wet temperature rating maintains flexibility even in harsh conditions (rated to -40°F/C), resisting salt water, battery acid, fuel, oil, UV radiation, and mechanical abrasion. Unlike standard electrical wire, this formulation won't harden or crack in extreme marine environments, ensuring long-term circuit integrity and safety. The 1.1-pound spool provides enough wire for typical cabin re-runs, control circuits, or system expansions without waste.

This wire is essential for weekend anglers upgrading fish finder wiring, serious offshore operations expanding electrical capacity, and professionals maintaining charter fleets or commercial vessels. The brown insulation aids circuit identification in complex wiring harnesses, reducing installation errors. Paired with quality marine connectors and proper crimping tools, Ancor tinned copper wire forms the foundation of electrical systems that function reliably for 10+ years in saltwater service—a standard that uninsulated or bare-copper alternatives simply cannot meet.
