Ancor 14 AWG Tinned Copper Marine Primary Wire — 100 ft Black, Ultra-Flexible, Corrosion-Resistant

Ancor 14 AWG tinned copper primary wire is a 100-foot black, ultra-flexible marine cable designed to resist corrosion, vibration and harsh marine conditions.

This heavy-duty 14 AWG wire from Ancor is built for boats, RVs and other demanding environments where long-term electrical reliability matters. It combines fine Type 3 stranding with a tin-plated finish and premium vinyl insulation so the conductor stays flexible, resists saltwater and chemical exposure, and meets marine safety standards. The single-reel 100' length gives you enough lead for runs, replacements or retrofit projects without splicing multiple lengths.

How does this wire hold up in saltwater and humid environments?

The conductor is made from multiple fine copper strands that are tinned, creating a barrier to oxidation and galvanic corrosion. Tinning significantly slows the formation of copper oxides, which helps maintain low resistance and good conductivity in wet or salty conditions.

• Type 3 fine stranding for fatigue resistance under vibration
• Tinned copper finish reduces corrosion in marine atmospheres
• Insulation resists salt water, battery acid and UV exposure

Is this cable flexible enough for tight spaces and frequent movement?

Yes — the wire uses ultra-flexible Type 3 stranding that bends easily and withstands repeated motion without breaking. The vinyl jacket remains pliable even at very low temperatures, making routing through confined conduits or around bilge areas straightforward.

• Type 3 multi-strand construction for increased flexibility
• Remains flexible down to -40°F/°C for cold-weather performance
• Suitable for vibration-prone installations like engines and helm stations

Does this meet marine and safety standards for on-board wiring?

Ancor's 14 AWG tinned wire is built to exceed relevant marine and electrical codes, giving installers confidence that it complies with common regulatory requirements. It carries ratings suitable for both dry and wet conditions and matches industry expectations for vessel wiring.

• Exceeds UL 1426 for marine wiring applications
• Meets US Coast Guard charter boat requirements (CFR Title 46) and ABYC standards
• Insulation rated 600 volts, 105°C dry and 75°C wet

What chemicals, temperatures and mechanical stresses can this insulation withstand?

The premium vinyl insulation provides broad resistance to common onboard hazards so the wire continues to perform in aggressive environments. It protects the conductor from oils, fuels and sun exposure while maintaining safe voltage ratings and temperature tolerance.

• Resists battery acid, oil, gasoline and abrasion for long service life
• UV-resistant jacket prevents cracking and degradation from sunlight
• Thermal ratings support typical marine and vehicle electrical systems

Who is this for? This 100-foot spool of Ancor 14 AWG tinned copper wire is tailored for boat owners, marine electricians, RV builders and anyone needing a reliable, corrosion-resistant conductor for 12V–24V systems and similar applications. It’s ideal for repowering panels, replacing degraded wiring, wiring accessories, or running new circuits where flexibility, environmental resistance and code compliance are priorities. Choose this wire when you want a durable, inspection-friendly cable that stands up to vibration, moisture and chemical exposure without sacrificing ease of installation.
