Marine grade wire is manufactured in multiple gauges for different applications. Use the charts below to determine the correct wire gauge, based on the amount of current in the circuit and the length of the wire run.
MARINE WIRE SIZE AND AMPACITY. Even seasoned professionals may occasionally need to verify the appropriate wire gauge and ampacity (the maximum electrical current a conductor can handle) for a given marine DC load. We've established a straightforward method based on the following charts:
There are two ways to find the correct AC wire size: The first is to consult the American Boat & Yacht Council (ABYC) AC wire sizing charts found within ABYC Standard E-11. Boaters can access ABYC standard E-11 by going to the ABYC website. Navigate to the recreational boater area, and click on the "become a member" link.

ABYC Ampacity Tables. On this page, you can download the official ampacity tables from the ABYC E-11 standard as PDF. They are the basis for calculating wire sizes on your boat. We also included the ABYC voltage drop tables.
Quality marine wire, as specified by ABYC standards, will always be stranded rather than solid, and always tin-plated copper. In addition, the DC Wire Selection Chart shown below assumes a wire insulation rating of 105°C. A lower rating will decrease the current-carrying capacity of the wire.
