Buying Guide

Choose tinned copper conductors

Tinned copper resists corrosion in marine environments and improves long-term electrical reliability compared with bare copper

Match the correct AWG

Select wire gauge by circuit load and run length—12 AWG for higher-current runs, 14 AWG for general circuits, 16 AWG for low-current accessories

Consider duplex or multi-conductor options

Duplex or multi-conductor cable simplifies installations for paired circuits like power and ground or signaling and power

Confirm insulation and marine rating

Use insulation rated for marine use (UV, oil and heat resistant) to withstand deck exposure and engine-bay conditions

Pick appropriate spool length

Choose lengths that minimize joints and spare extra for routing; common lengths include 50 ft and 100 ft spools
