Buying advice

For marine wiring, always use tinned copper wire to resist corrosion. Match wire gauge to your load; 10-12 AWG works for most accessories, 8 AWG or thicker for high-current needs. Consider insulation type and flexibility based on installation location (e.g., engine room vs. cabin). Check for certifications like UL or ABYC for reliability.
