Fusing Guide

Note that the main feed from the battery is fused to protect this section of cable and this cable should be large enough to supply the current required by all the loads operating at the same time (worst case).

Battery Terminal (Cube) Fuses | 12 Volt Planet

They are often used on main power feeds from batteries to inverters, bow thrusters, windlasses, etc. Terminals clamps or bolt-down fuse blocks are available that allow the fuses to be fitted directly to your battery terminals, providing maximum protection by completely eliminating any un-protected section of cable between the battery and the first fuse.

How to Properly Fuse Your Solar System

To find the right fuse size, multiply the inverter''s max current by 1.25 to 1.5. For instance, a 1500-watt 12V inverter draws up to 125 amps. So, you need a fuse for 156 amps, adding 25% for safety. Installation Placement Considerations. Put the fuse close to the battery. This reduces wire damage risk if there''s a fault.
