Pacer 18/2 AWG Safety Duplex Cable - Red/Yellow - 100'

The Pacer 18/2 AWG Safety Duplex Cable in red and yellow delivers reliable low-voltage connectivity for marine DC and AC applications. Built from finely stranded, tinned copper conductors, this 100-foot duplex boat cable resists corrosion in salt-air environments while maintaining the flexibility needed for routing through tight boat spaces and equipment installations.

The 18 gauge construction balances current capacity with manageable wire diameter for navigation lights, bilge pump circuits, and auxiliary 12V systems found on center consoles, cabin cruisers, and fishing boats. Pacer manufactures this cable in-house in the USA, ensuring consistent conductor quality and PVC jacket performance across the full 100-foot spool. The color-coded red and yellow conductors simplify polarity identification during installation, reducing wiring errors on the water. The flexible PVC jacket maintains its integrity in UV exposure and temperature cycling without cracking or brittleness.

This duplex cable is designed for DIY boat owners, marine electricians, and outfitters upgrading or repairing onboard systems. Whether running auxiliary circuits, replacing corroded original wiring, or installing aftermarket electronics, the proven tinned-copper construction outlasts bare copper in harsh saltwater conditions. The 4.2-pound spool is easy to manage during installation, and the long 100-foot length minimizes splices on larger vessels.

When selecting marine duplex cable, gauge matters as much as corrosion resistance. 18 AWG handles moderate-current loads at typical boat voltages while remaining flexible enough for routing around structural obstacles—a key difference from rigid single-conductor alternatives. Proper cable gauge and connector sizing prevent voltage drop and heat buildup on longer runs below deck.
