PowerPosts were the first products made by Blue Sea Systems. Now they make a bewildering collection. How do you select which one to use? What is the alternator field disconnect terminal on a battery switch for?

Alternators
Many battery switches come with a pair of small terminals labelled "Alternator Field Disconnect" or AFD. Of all my years working on marine electrical systems I have never once seen these terminals hooked up correctly. What are they for and how should they be wired.........Installing a Balmar alternator on a Yanmar 3JH3E

Here is a short video clip, some photos and a description of a project to replace the standard alternator on a Yanmar 3JH3E with a Balmar 60-100-SR-IG alternator. The boat is a Dehler 38 Sailboat and as it is going on the Annapolis to Bermuda race next summer the owner wanted to have plenty of power available for the trip.

Circuit Protection
ABYC Standard 11.10 OVERCURRENT PROTECTION is a key section of the standards. The principal is very clear, an overcurrent device, such as a fuse or circuit breaker, needs to be placed within seven inches of where the conductor is connected to the source of power. The overcurrent device is protecting THE WIRE from carrying more current than it is able. What follows is an outline of this part of the standard but please see the disclaimer at the end.

This is an outline review of the ABYC standards relating to Electrical Systems. It just highlights the subject area of each standard. Further Blog Posts will delve into the details of the standards. The ABYC standards are a voluntary set of standards written and maintained by the American Boat and Yacht Council. They cover the design, manufacture and outfitting of small craft built in the US and compliment the compulsory standards written by the US Coast Guard. Each ABYC standard is updated every five years. The USCG standards are covered in a separate Blog post.

Blue Sea Systems Custom 360-Series Circuit Breaker Panels.This is a very simple 230 Volt AC panel that was shipped to New Zealand. The boat owner already had a single 360-Series panel on board which he liked so much he decided to redo the entire AC system and so this panel has a blank which will be replaced by his existing panel.
