Marine-grade wiring provides peace-of-mind when far from shore.
Sophisticated marine electronics and instruments operate at peak potential only when supplied with power at the right voltage, which necessitates high-quality wire like the primary wire from anchor.
Ordinary automotive-type wire can suffer a loss of conductivity after a few months in the marine environment.
Corrosion occurs and corrodes the copper conductor when the wire's jacket and insulation are compromised by water intrusion.
Marine-grade wire from Amcor 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 stripped).
Vibration is always present on a boat and will quickly fatigue and crack coarsely stranded wire.
Amcor wire is type 3 stranded, meaning 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 rated at 600 volts, 221 degrees (105 degrees) dry and 167 degrees (75 degrees) 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 sea gauge wire.
Thus, it offers more current-carrying ability than similar sea wire.
