Review on ZOOKOTO Circuit Breaker Inverter Waterproof by Steve Campbell

Used to isolate the solar panel from the MPPT load. Installation was easy. With thicker wires, it was a bit difficult to get the wire around the nut. I'm not 100% sure about the size, but I think 8 gauge. There are also nuts in the screw holes. I tried turning them off but couldn't get them to move. I finally found a smaller screw that fit through the hole in the wood where I attached the switch and charger wiring. Overall it's what I needed, but the dimensions were a bit small for the wiring I had and I have no idea why a nut is fitted (and no screws are supplied).
