Frequently asked questions about Blue Sea Systems

How do I choose the right fuse for my boat?

The fuse should match the maximum current rating for the circuit and be rated for the voltage you are using on board. Also, check the fuse’s physical size and type to ensure it fits your fuse holder.

What is the difference between a main switch and a battery selector?

A main switch disconnects power to the entire boat's electrical system, while a battery selector allows you to choose between multiple batteries or combine them. Choose based on how many batteries you have and how you want to manage power.

What plugs and connectors should I choose for the boat?

Choose plugs and connectors that match the voltage and current rating of your system, and which have an IP rating that protects against water and moisture. Also, check if they are easy to install and compatible with your wiring.

Can I install Blue Sea Systems products myself?

Many of the products are designed for easy installation, but it requires basic knowledge of the boat's electrical system. If in doubt, it is recommended to seek help from a professional.
