DIY copper bus bar

Ampacity of copper bus bars. Your 3/4" pipe should be fine as the load from your batteries is probably never going to be above 100-150 Amps. I used a bolt on fuse at the bus and that is probably a good idea for your project. Midi fuses

Tip: Drill slow when drilling copper.

For those wishing to make there own buses with copper bar stock, I bought my bars at Discount Steel. They have a yard close to me but they will also ship.

When I was a kid, we made our own lead soldiers. We heated lead on the kitchen stove and poured it into molds. I think I still have the molds. We also played with mercury out of thermometers, poured gas into water buckets and lit it, and I even had a Chemistry Set. It's amazing that I'm still here, lol.

I was planning on using the fuses but not quite sure what to use for the main line fuse? I will have a main line coming into the box off the battery then heading out to my disconnect switch. What size fuse should I use here? The draw could be anything from 0 to 150 amps depending on the load at the time. Not sure if it even needs a fuse as its not fused right now and the line ends up in the converter fuse box?

I am adding fuses for the solar and inverter.
