Buying Guide

Choose the right AWG for load

Match wire gauge to circuit amperage and run length to avoid voltage drop and overheating

Prefer tinned copper conductors

Tinned copper resists corrosion in marine environments better than bare copper, improving longevity

Pick appropriate cable construction

Use duplex/flat cable for chassis and lighting runs and multi-strand single conductors for battery and high-current lines

Check insulation type and temp rating

Select marine-rated insulation with UV and heat resistance to handle engine compartments and exposed runs

Consider spool length and installation needs

Longer reels reduce joins on long runs; pre-assembled duplex reduces wiring time for paired circuits
