Seachoice 4TC-BLACK-BATTERY-50 Tinned Copper Marine Wire 4 AWG Black 50 Feet

The Seachoice 4TC-BLACK-BATTERY-50 is a premium 4 AWG tinned copper marine wire designed for demanding marine electrical applications. This 50-foot spool of black marine-grade wire exceeds industry standards including UL 1426, ABYC, and USCG requirements, ensuring reliable performance in harsh saltwater environments.

Key Features:

• Ultra-flexible Type 3 tinned copper stranding resists corrosion, electrolysis, and fatigue from vibration
• Premium vinyl insulation rated for 600 volts, 105°C dry and 75°C wet conditions
• Maintains flexibility in extreme cold down to -40°F/-40°C
• Excellent resistance to salt water, battery acid, oil, gasoline, heat, abrasion, and UV radiation
• 4 AWG gauge suitable for high-current battery, starter, and windlass applications
• 50-foot length provides ample wire for installation projects

This marine-grade wire is ideal for battery connections, bilge pumps, windlasses, bow thrusters, and other high-amperage 12V or 24V marine electrical systems. The tinned copper construction provides superior protection against the corrosive marine environment compared to bare copper wire, extending service life and maintaining conductivity.
