Review on Sperry Instruments CS61200 Circuit Breaker by Carl Durant

It will probably work with Chinese circuits where it is made. He gave me several references on circuit breakers so you have no idea what circuit I was working on. I ended up blowing out 42 individual circuit breakers one at a time and walking up and down the stairs over 42 times to get the desired results, and it took hours to do so. Save your money.! And yes, I followed the manufacturer's instructions. I've tried using the detector rod in several different positions with the same results. My panel is new and unlabelled. Throwing away the switch and hoping for the best to find the circuit worked for me, but that means restarting clocks, computers, etc, and it's a pain in "yes, you get it"! I wanted the device to label my panels better to avoid this problem. If you get frustrated and want to train hard, then this is the device for you! I gave the mess to Goodwill. Maybe it was a mistake.
