Klein Tools ET300 Circuit Breaker Finder
Our precarious octopus wiring leads to blown circuit breakers, which inevitably leads to a frantic toggling of them all in order to find the right one. And while ID’ing the circuit we want to shut off when we need to expose some wires requires similar trial and error, Klein Tools’ ET300 Digital Circuit Breaker Finder simplifies the search. Just insert the included test plug into the circuit and then run the tester over the circuit breakers twice: once to calibrate, and another time to identify the targeted circuit. The powerful transmitter also works through up to 1,000 feet of wiring, making this a solid toolkit addition for anyone doing occasional electrical work.
