Review on Siemens Q23050CT2 30 Amp Circuit Breaker: Highly Efficient and Reliable Electrical Protection by Daniel Oliver

I thought it was a good product but it's not. I finally got to my rewiring project, and lo and behold, this switch had a Phillips head screw. After trying to loosen this screw, I broke the breaker. Yes I probably could have tried to return it but at that moment I just threw it in the trash and went to the electric company in town and bought a replacement. After all, I've had the power outage a little longer than anyone wanted. So my advice, if defects matter, check it out. Otherwise the switch looked like any other switch.
