The CB10-KIT is an electrical troubleshooting kit that includes three tools and five functions. The CB10 is an AC Circuit Breaker Finder/Receptacle Tester that finds circuit breakers and checks receptacle wire. The CB10 enables the user to rapidly detect 110-Volt to 125-Volt AC circuit breakers and fuses using auditory and visual (LED light) circuit breaker indicators. The product also has a configurable sensitivity adjustment for pinpointing the correct circuit breaker. The second tool is the CT20, a Continuity Tester/Wire Tracer that tests continuity with a bright flashing LED and a loud pulsing beeper. The remote probe with LED lets a single operator trace up to three cables. The third tool in this kit is the DV20, which is an AC Voltage Detector/Flashlight that detects AC voltage without touch.
