Frequently Asked Questions (FAQs)

1. What wire do I use for boat wiring?

The ABYC recommends wire conductors of at least 16-AWG (gauge) for lights and other similar equipment. That's minimum, and heavier gauge isn't much more expensive — and generally no more trouble to install. We suggest you use 12- or 14-AWG to minimize your voltage drops, or more if the manufacturer suggests it.

2. What is boat cable?

Boat cable is a type of electrical cable designed to be flexible, durable, easy to install and resistant to the harsh marine environment. Often times, people fail to consider just how hazardous the marine environment can be. This can lead to the assumption that other types of cable are sufficient for use.
