Typically a 4-8 gauge wire is recommended.

Smaller Appliance = Smaller Wire = Smaller Fuse

Install small wires to the shunt.

Improper size connector: all connectors are rated for a specific gauge of wire and no other.

The wires that attach to these components are typically the largest wires in a system and will supply power to all appliances.

If you would like to wire the fuse block directly to the large bolt-on fuse that is located on the battery bank, you need to use a thick wire. This wire should be at least 6 gauge.

The size of the fuse is determined more by the thickness of the wire than anything else.

Wires that supply electricity to appliances are typically 12 gauge.

If your fuse block is small, and cannot handle a 6 gauge wire, you will need to fuse the wire that supplies the fuse block.
