We run all the power from the battery to this fusebox, which then gives us up to 12 circuits for all the van systems.

This is a pretty solid fusebox, but one thing to note is that it has 2 separate 6-way positive buses. That’s a feature that some people need, but we don’t. So we just fabricated a simple copper bridge out of flattened plumbing pipe to connect the 2 positive terminals.
