Ancor Dark Blue 16 AWG Tinned Copper Wire - 25'

Ancor Dark Blue 16 AWG Tinned Copper Wire in 25-foot lengths is the marine electrician's choice for reliable onboard wiring in saltwater and freshwater environments. Whether you're running navigation lights, installing new console instrumentation, or repairing corroded connections on a center console, transom, or cabin cruiser, this wire delivers the durability that separates emergency repairs from lasting solutions. Built to withstand the harsh corrosive marine environment, it meets or exceeds UL 1426, ABYC, and US Coast Guard CFR Title 46 standards—the same certifications required for charter boat electrical systems.

The 16 AWG gauge provides ideal current capacity for mid-load circuits—bilge pumps, trim tabs, and smaller lighting arrays—without unnecessary bulk in tight engine compartments or tight behind-dash runs. Tinned copper construction is the critical difference here: the tin coating resists oxidation and corrosion far longer than bare copper, which is essential when salt spray and moisture exposure are constant threats. Premium vinyl insulation is rated to 600V and 105°C, ensuring the wire remains flexible and protective even after years of vibration, heat cycling, and UV exposure from sun and reflected light off the water. The 25-foot spool length covers most single-circuit repairs or new installations without waste.

This wire is ideal for anglers upgrading fish finders, GPS plotters, and autopilot systems, as well as boaters performing routine electrical maintenance. The 16 AWG diameter suits connections where space is constrained—through bulkheads, along stringers, and behind instrument panels—while still handling the amp load of typical accessory circuits. When paired with proper marine-grade connectors and heat-shrink tubing, Ancor tinned copper wire ensures connections that won't fail mid-season or require replacement after a single saltwater season.
