Frequently Asked Questions (FAQs)

1. What is a fuse block?

A fuse block is used to distribute power in vehicular electrical systems. Although the term “automotive fuse block” is frequently used, a fuse block can be used in not just cars and trucks, but also RVs, watercraft, motorcycles, and any other 12V or 24V system. “Fuse panel” is another common name for a fuse block.

2. Are Blue Sea fuse blocks waterproof?

Features: Water-resistant design with standard ring or fork type terminals allows for simple wiring with standard tools. Accepts a wide range of wire sizes. Includes 3 wire plugs to maintain water resistant rating if less than 4 loads are required.

3. What is the difference between a fuse holder and a fuse block?

How is a fuse holder different from a fuse block? A fuse holder is designed to handle a single fuse and is often installed inline. This is vastly different from a fuse block where you have a large device that holds up to twelve different fuses.

4. Why are two fuse blocks used?

For single-phase, single-voltage plug-and-socket-connected equipment, double fusing ALWAYS provides protection for both kinds of faults regardless of whether polarity reversal is possible or not.
