Pacer Black 18 AWG Primary Wire - 250'

The Pacer Black 18 AWG Primary Wire – 250' is purpose-built for marine electrical systems where durability and reliability are non-negotiable. Whether you're wiring a new console, upgrading your boat's charging system, or running power to auxiliary equipment, this 250-foot spool delivers the length needed for most mid-sized vessels without splice joints in critical runs. Marine environments demand wire that resists corrosion, salt spray, and the constant vibration of the engine compartment—this product is engineered exactly for those demands.

Constructed to meet and exceed stringent marine specifications, this 18 AWG primary wire is manufactured in the USA using materials proven to handle harsh saltwater and freshwater environments. The 18-gauge copper conductor is appropriately sized for moderate-amperage circuits—typical applications include nav lights, bilge pump wiring, and auxiliary charging systems—while the marine-grade insulation resists UV degradation, oil, fuel, and temperature extremes found in engine rooms and exposed deck installations. The black jacket provides visibility against wiring harnesses and makes tracing connections straightforward during troubleshooting or future upgrades.

Boaters upgrading from corroded or undersized wiring will immediately appreciate the confidence that certified marine-grade wire brings to their electrical system. The 250-foot length eliminates the need for multiple shorter spools on larger installations, reducing connector joints and potential failure points. Installation pairs easily with standard crimp terminals and marine-grade breakers; always match wire gauge to circuit amperage and breaker rating per ABYC (American Boat and Yacht Council) standards for safe operation and coast guard compliance.
