Pacer Black 18 AWG Primary Wire - 1,000'

The Pacer Black 18 AWG Primary Wire – 1,000' spool is purpose-built for marine electrical systems where corrosion resistance and long-term reliability are non-negotiable. Constructed from Type III class K tinned copper, this marine wire delivers the electrical conductivity and flexibility needed for everything from console wiring to thruster circuits on boats of all sizes. The 1,000-foot length covers most single-vessel projects without multiple spools, and the tinned copper construction resists saltwater corrosion far more effectively than bare copper alternatives.

At 18 AWG, this wire handles mid-range power distribution tasks—ideal for accessory circuits, lighting, and sensor wiring rather than high-amperage direct battery connections. The tinned copper core maintains flexibility in cold water conditions, preventing brittleness that can lead to insulation cracking. Class K construction ensures the wire meets strict marine specifications, exceeding the requirements of the harshest saltwater environments where standard automotive or industrial wire fails within months. The 11.1-pound spool is compact enough to store on deck or in a cabin locker without taking up excessive space, while the 7×7×7 inch footprint allows easy handling when pulling wire through conduit or cable runs.

Weekend fishermen upgrading older boats will find this wire essential for rewiring aging electrical systems; serious offshore anglers and commercial operators rely on tinned copper to eliminate corrosion-related electrical faults thousands of miles from port. Whether you're installing new electronics, rebuilding a livewell system, or running circuits for synthetic fishing lights, this marine-grade primary wire is manufactured in the USA to standards that don't compromise in salt air or spray conditions.

Marine primary wire specifications matter because they directly affect system uptime and safety. A corroded wire connection on the water isn't just an inconvenience—it's a failure point that can leave you stranded. Pacer Group's tinned copper formulation is the industry standard for this reason, backed by decades of performance data in commercial fishing and military marine applications.
