Buying Guide

Choose the right gauge

Match wire AWG to your circuit amperage to minimize voltage drop and heat; common boat gauges include 2, 8, 12, 14, 16, and 18 AWG

Prefer tinned or oxygen‑free copper

Tinned and oxygen‑free copper resist corrosion in marine environments and improve long‑term conductivity compared with bare copper

Pick duplex vs single conductor wisely

Use duplex/flat cable for simple positive/negative runs and single conductors for custom routing or battery cables

Consider length and voltage drop

Buy sufficient length for run routing while accounting for voltage drop — longer runs may require a thicker gauge

Check insulation and IP ratings

Look for marine-grade insulation and IP68 or similar waterproofing for exposed runs and bilge areas
