Product Details

12 Gauge Marine Tinned Primary Wire

12 AWG - Nominal OD Size: 5/32"

Constructed to American Wire Gauge standards, AWG wire is up to twelve percent larger than the equivalent SAE wire sizes. AWG wire provides a greater current capacity when compared to SAE gauge wire.

Marine Tinned Wire and Cables are manufactured from tin coated copper strands for maximum protection against corrosion, electrolysis and resists fatigue due to vibration and flexing.

Rated at 600 volts and 105 degrees C, the heavy duty insulation is resistant to heat and abrasion. Exceeds all UL1426, US Coast Guard Charterboat (CFR title 46) and ABYC standards.
