ANCOR 10 AWG Primary Wire by the Foot

Marine-grade wiring provides peace-of-mind when you're far from shore.

Sophisticated marine electronics and instruments only operate at peak potential when supplied with power at the right voltage, which necessitates high-quality wire like Ancor's Primary Wire. Ordinary automotive-type wire can suffer a loss of conductivity after a few months in the marine environment. Corrosion takes place, and corrodes the copper conductor, when the wire’s jacket and insulation are compromised by water intrusion. Marine-grade wire from Ancor is rated for oily and wet environments because its jacket is impervious to those conditions. Each strand has a tin coating for extra corrosion resistance (note the “silver” look when you strip it). 

Vibration is always present on a boat, and will quickly fatigue and crack coarsely stranded wire. Ancor wire is Type 3 stranded, meaning that it has 5-10 times more copper strands than Type 2 wire, making it more flexible and fatigue resistant. It is constructed with premium vinyl insulation that is rated at 600 volts, 221°F (105°C) dry and 167°F (75°C) wet. It is also Marine UL-listed, and meets the highest ABYC standards for AC and DC use. Finally, it is based on AWG (American Wire Gauge) wire sizes, which are 6-12% larger than SAE gauge wire. So you get more current-carrying ability than from similar SAE wire.
