Excellent work
Replace faulty breaker.
I was tasked with replacing smoke detectors in a residential building. I started by checking the existing detectors to ensure they were interconnected and working properly. If any of the detectors were not working, I replaced them with new ones. I also made sure that the detectors were installed in the correct locations and that the wiring was properly connected. After completing the replacements, I tested the detectors to ensure they were working correctly.
