Key Features


  • Quickly and accurately locates the correct circuit breaker in a panel

Overview


Operating the Klein ET310 circuit breaker finder is simple. You plug the Transmitter into the outlet in question and head to the panel with the Receiver to find the circuit. When the receiver is on, the tip illuminates in green. When the receiver locates the correct circuit, a red light illuminates and an audible indicator sounds.


Finding breakers in a busy panel can be a time-consuming task but is made simple by the use of a capable circuit breaker finder. The ability to quickly and accurately find the correct breaker to which a specific outlet of a fixture is connected the first time, every time, delivers great efficiency to the electrician. It also prevents the unnecessary powering-down of circuits not involved in the task at hand to provide the least disruption to other activities and people.

Testing a GFCI circuit is easy, simply press the Transmitter’s gray button to simulate a trip. If it fails, a replacement is in order. The Transmitter also has the familiar legend of correct and incorrect wiring that corresponds to various combinations of its three LEDs.


The Klein ET310 AC circuit breaker finder consists of two parts that can be connected to reduce the chance of losing one of the pieces. The end of the receiver looks like an outlet so you can plug in and store the transmitter after each use.

The Klein Tools ET310 is built to withstand a 6.6-foot drop. The tool also carries a CAT II 120V rating and has a 3-minute auto power-off timer to preserve the battery.
