Review on 🔌 JOYHO 100 Amp Circuit Breaker with Manual Reset for Marine RV Car Audio: Waterproof Fuse Holder for Solar System Amps Protection by Raysean Forth

The first problem is that the terminal's contact surface is recessed under the 1mm thick plastic lip, which most likely does not provide a good contact surface. Without tripping up for other reviewers, I suspect this causes the breaker to get very hot. Another issue is that there are two exposed metal dots on the back, each connected to a different port. The closure of these two points completes the circuit. A rivet does not fully seat the cap, resulting in an open gap and the possibility of water ingress. There is no identifying information other than the 100A rating. There is no voltage rating or serial number. Even the manufacturer does not want to put his name on it.
