Primary Cable

Primary marine wire for low-voltage DC circuits, accessory wiring, controls, and general-purpose onboard electrical installations. Single-conductor primary marine wire is widely used for low-voltage DC power, bonding and control wiring. Choose conductor gauge by continuous current, run length and allowable voltage drop, then confirm insulation temperature, oil/moisture resistance and color coding. Fine-stranded tinned copper improves flexibility and corrosion resistance where specified for marine use.
