## Description

The Fluke BK120 SmartTrace Breaker Finder is a tool for identifying circuit breakers in electrical panels and detecting voltage with the NCV mode. It is an essential device for electricians, homeowners, and maintenance professionals, to simplify electrical work, circuit tracing, and troubleshooting. The product includes a receiver that acts as the Breaker Finder and non-contact voltage detector, and a transmitter that traces to the receiver and also acts as a socket tester.

Review: Excellent for tracing circuits. - Excellent, circuit tracer. The transmitter is powered by the AC, so no batteries needed. The receiver works great, is easy to use. After plugging in the transmitter, make sure you hold the receiver perpendicular to the breakers. Scan all breakers once and ignore the beeps, as it’s automatically adjusting the sensitivity on the first scan. Then scan again and you’ll get very accurate locating information. I tried a cheaper scanner first that had a very nice digital transmitter with an OLED display. It required batteries and showed voltage and wiring faults, but it completely failed at tracing circuits. I was very careful to follow the instructions exactly. I highly recommend the few extra dollars for this Fluke, it was well worth the extra $20. I bought a box for it.
Review: A must for anew heomowner and handyman - A great tool for testing GFI plugs and for finding a breaker for power outlets. I wish somehow it also worked for light switches/circuits. The only drawback I found is that it is recommended that all outlets are vacant when testing. The voltage detection works very well.

### ⭐⭐⭐⭐⭐ Lifesaver for this old house.
*by K***R on June 29, 2026*

Worked great (it's a Fluke!) - super useful and a bit of a lifesaver when figuring out the state of the electric sockets and lights for an old house - where the very confused power circuits resulted from many different electricians working on the house over the years. The socket tester is super easy (every household should have one) and live circuit tester saved me a few times. The breaker finder takes a little getting used to - to get results you expect - but once you figure it out, it is very predictable.
