Ancor Dark Blue 12 AWG Tinned Copper Wire - 100'

The Ancor Dark Blue 12 AWG Tinned Copper Wire — 100' spool delivers marine-grade electrical connectivity built to withstand saltwater environments and harsh offshore conditions. Tinned copper construction provides superior corrosion resistance compared to bare copper, making this wire ideal for boat wiring, marine electrical systems, and applications where salt spray, moisture, and UV exposure are constant threats. This 12 AWG wire meets or exceeds UL 1426, ABYC, and US Coast Guard CFR Title 46 standards — the regulatory benchmarks that govern marine safety installations.

Premium vinyl insulation rated at 600V with temperature handling from -40°F to 105°C (dry) and 75°C (wet) ensures the wire remains flexible in extreme cold and maintains electrical integrity in the wet, humid marine environment. The insulation formulation resists salt water, battery acid, oil, gasoline, heat, abrasion, and ultraviolet radiation — the full spectrum of degradation factors found aboard working boats. The 100-foot length accommodates medium runs throughout cabin wiring, bilge pump circuits, battery banks, and navigation system installations without requiring splices.

This wire suits weekend fishermen upgrading basic electrical systems, offshore anglers installing redundant battery and charging infrastructure, and professional boat builders meeting regulatory compliance. The 12 AWG gauge handles 20-25 amp continuous load in typical marine applications, making it suitable for running lights, cabin circuits, and auxiliary equipment without undersizing risk. Tinned copper eliminates the corrosion failures that plague bare copper in salt air, extending service life and reducing maintenance troubleshooting on the water.
