Buying Guide

Choose the right AWG for the circuit

Match wire gauge to your circuit's amperage and length—12 AWG for higher-current runs, 14 or 16 AWG for lights and low-current accessories—to minimize voltage drop and overheating

Prefer tinned copper conductors

Tinned copper resists corrosion in marine environments better than bare copper, improving longevity in saltwater and humid conditions

Look for flexible, stranded cable

Flexible stranded or duplex cable simplifies routing through tight spaces and withstands vibration better than solid conductors

Check insulation and jacket material

Marine-rated insulation designed for UV, oil, and moisture resistance helps prevent cracking and degradation on boats

Consider length and spool size

Buy a length that covers your run with some slack—available spool sizes (25–100 ft) affect installation ease and waste
