Ancor Tinned Copper Marine Wire 16 AWG (1 mm²) — 100 ft Yellow, Type‑3 Ultra‑Flex, 600V

Ancor 103010 is a 100‑foot roll of 16 AWG (1 mm²) tinned copper marine wire in yellow, built for corrosion resistance and extreme flexibility.

This marine‑grade cable combines fine, Type‑3 stranding with a tin coating on each copper strand and a premium vinyl jacket to withstand saltwater, vibration and harsh outdoor conditions. Rated for 600 volts and designed to stay flexible at very low temperatures, it meets UL 1426, US Coast Guard Charterboat (CFR Title 46) and ABYC requirements for marine electrical systems.

How does this wire resist corrosion and electrolysis?

The copper conductors are tinned after stranding, which creates a protective barrier against oxidization, saltwater and galvanic action. Tinning reduces the chance of strand‑by‑strand corrosion that can increase resistance or cause failure in wet or marine environments. The vinyl jacket adds a second layer of chemical and UV resistance.

• Individual copper strands are tinned to prevent oxidation
• Type‑3 ultra‑flex stranding reduces fatigue from vibration
• Vinyl insulation resists salt water, battery acid and UV exposure

Is this cable appropriate for onboard power and battery connections?

Yes — the 16 AWG size and 600‑volt insulation rating make it suitable for many low‑voltage DC circuits, accessory wiring and battery connections where 16 AWG is specified. The wire’s flexibility eases routing through tight spaces and around bends commonly found in boat installations. Always match wire gauge to the circuit amperage and follow boat manufacturer or ABYC recommendations.

• 600 V insulation and 105°C dry / 75°C wet temperature ratings
• Flexible Type‑3 stranding for routing through confined spaces
• Compatible with marine electrical standards and common battery systems

How does the insulation hold up to temperature, chemicals and abrasion?

Ancor uses a proprietary premium vinyl jacketing that remains flexible down to -40°F/C, resists common boat fluids and maintains mechanical protection against chafe and abrasion. The material is tested to withstand UV exposure, gasoline, oil and battery acid — helping prevent cracking or hardening over time. For added mechanical protection, use conduit or loom where chafe is expected.

• Rated flexible at extreme cold temperatures (-40°F/C)
• Resists gasoline, oil, battery acid and UV degradation
• 600‑volt insulation with good abrasion resistance for marine use

What installation and maintenance tips should I follow?

Plan runs to minimize sharp bends and avoid high‑heat areas; secure the cable at regular intervals to reduce vibration stress. When terminating, use compatible marine‑grade heat shrink or solderless crimp terminals designed for tinned copper to preserve corrosion resistance. Inspect connections periodically for signs of chafe, moisture ingress or loose terminations.

• Use marine crimp terminals or heat‑shrink tubing for sealed connections
• Support cable with clamps every few feet to reduce vibration wear
• Avoid routing near exhausts or engine blocks without heat protection

Who is this for: The Ancor 103010 16 AWG yellow tinned copper wire is aimed at boat owners, marine electricians, and hobbyists who need a reliable, flexible conductor for onboard accessories, lighting, small pumps and control circuits. It’s also useful for RV, outdoor power and any application where salt, vibration and UV exposure demand a tougher wire than standard stranded copper.
