Adding a Master Fuse to the Battery Post

I am installing solar panels and a larger battery so that we can boondock without a utility hookup and still run our electrical devices. The first step was to install a master fuse at the battery post, before any wires. This is an 80 Ampere fuse that would handle a short close to the battery.  A cut-off switch and a small fuse panel near the battery will be installed next.

This is the battery before the fuse holder is installed.

Here’s the fuse holder. It will install directly onto the battery post, and provides a second post which is protected by the fuse. This is manufactured by Blue Sea Systems.

The fuse is mounted on the post. The post is isolated, so all power flowing through it comes through the fuse.

Here's the mounted fuse, and the much smaller inline fuse we're replacing. A 1/0 gauge wire will go from the fuse holder to a master cut-off switch, and from there to a fuse panel which feeds to the power converter, the emergency brake, and the solar charger.
