Electrical Systems
Resources

I enjoy spending time as an instructor at Mary Goff's Narragansett Sailing School in Warwick and Barrington, RI.

This page has resources I found helpful when preparing for a brief workshop on marine electrical systems.

AC vs DC Current

Alternating vs direct current - this 10 second video is a quick and simple visual.

Simple example of a 12V DC marine circuit from safe-skipper.com.
This page also links to a great electrical system run-through.

Boat US has compiled a solid article summarizing common electrical hazards (with great photos).
