As followers of this blog may recall, we had a fuse between our solar panels and the solar controller:

I had an issue where that fuse blew a few times, possibly due to our extra solar panels putting out too much power. The most recent time I replaced it with a 30 amp fuse:

That didn’t end so well — a few months later, that fuse melted. Perhaps cheap junk, I don’t know; it should just blow, not melt. It set off our smoke detector, so could have been much worse:

I considered replacing the fuse holder, but figured I needed a better solution. I decided to replace it with a circuit breaker, so if it is over-current again it’ll just pop instead of blow or burn.

I needed a short length of wire to connect it, so went to the nearby Lowes for wire, using 8 gauge wire, the same as used elsewhere in the coach:

That was an adventure in itself; the guy who helped us wasn’t familiar with wire cutting, but he figured it out.

I connected a short length of that wire to the breaker:

I then drilled some holes for the wires above the solar controller:

And reconnected the controller to that wire:

Here’s the breaker installed, and preparing to re-mount the controller:

The completed breaker and controller (with the solar pulling in 14.4 amps):

Here’s hoping this solution will prove satisfactory!
