Buying Guide

Pick the right AWG for the circuit

Match wire gauge to circuit amperage and run length—12 AWG for higher-load runs, 16–18 AWG for lights and low-current accessories

Prefer tinned or oxygen-free copper

Tinned or oxygen-free conductors resist corrosion in marine environments and improve long-term conductivity

Choose marine-grade insulation

Look for PVC or cross-linked jackets rated for UV, oil, and salt exposure to prevent cracking and water ingress

Decide between duplex and single conductor

Duplex flat cable simplifies routing for paired runs like power/ground, while single conductors offer flexibility for custom wiring

Consider pre-measured lengths

Select 25–100 ft reels that match your typical run to reduce joins and potential failure points
