Photovoltaic single strand copper yellow/green ground electrical wires
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 wirelike Ancor's Primary Wire. Ordinary automotive-type wire can suffer a loss of conductivity after a few months in the marine environment.
