The Klein Tools ET310 Circuit Breaker Finder with Integrated GFCI Outlet Tester is a digital circuit breaker finder used to locate the correct circuit breaker in a panel to which an electrical outlet or fixture is connected. The Transmitter is connected to the electrical outlet or fixture in the circuit while the receiver is used to scan the breakers in the circuit panel. The Transmitter also features a GFCI outlet tester. Circuit Breaker Finder locates the correct breaker in a panel. Tester consists of two parts: a Transmitter and a Receiver. GFCI Outlet Tester integrated in receiver. Transmitter docks in the Receiver for convenient storage as a single item when tester is not is use. Transmitter incorporates a three-pin plug for connecting to North-American-style grounded electrical outlets. The transmitter may be connected to other electrical fixtures using optional accessories which are sold separately (Cat. No. 69411). Receiver powers off automatically after approximately three minutes of non-use to conserve battery life. Transmitter is powered by the circuit when connected to the electrical outlet or fixture. Low battery indicator. Easily accessible battery compartment. Uses one 9V battery in receiver only; Transmitter does not require a battery. Built to withstand a 6.6-Foot (2 m) drop.

Customer Comments:
1. Wish I had one of these 50 years ago. Finding the correct breaker used to be a slow trial and error time consuming method. This is really fast. As other reviewers noted other breakers may give a weak false positive but the correct breaker gives a very strong positive. A very handy tool for anyone working on electrical circuits in a house.
2. I spent some time reading reviews and watching videos on circuit breaker finders. I noticed the videos of this one seemed to work better than others I saw. In particular, I was considering one that had an adjustable sensitivity thinking that it would help when the device struggled between two breakers. I ended up with this one because of the description on how it's calibrated. It turns out that this calibration feature works very well to select the correct breaker. It's not 100% due to how close together two circuits run. It will trigger on two or in between two breakers. This happened for me only twice on two adjacent breakers. I found that by resetting and re-calibrating the unit on only the two triggering breakers and one on either side of them, it improved the selection of the correct breaker. I mapped out my electrical panel with 34 breakers in about 5 hours. I'm very happy with the purchase.
3. As the others complained, it's not always obvious which breaker is responding,especially with the older thin breaker type. Still if you can afford t
