Review on Enhanced Inverter Protection with ZOOKOTO Circuit Breaker by Rob Madden

I use it as a circuit breaker for my solar panels. The backup is an added bonus. It was easy to install, I connected 10 gauge wire to both ends. I believe it was a T5 torx head. But it seems like a good solid connection with nice insulated screw caps with rubber grips to keep dirt and water out of the plug. I wouldn't want to try anything bigger than 10 gauge. Although you could maybe go 8, doubt rubber stoppers could be used.
