FLUKE-BK120/5587527 SmartTrace Breaker Finder
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.
Highlights
A 3-in-1 tool that acts as a breaker finder, NCV detector, socket tester with a bright LED flashlight
Audible and visual alerts takes the guesswork out of locating circuit breakers
Unique dual-sensitivity NCV mode for non-contact voltage detection on terminal strips and supply cords
Transmitter has a built-in socket tester with easy-to-see LEDs to verify correct wiring in both standard and GFCI outlets
Auto sleep mode and low battery indicator


Dual Sensitivity
Indicates proximity and actual detection of AC voltage on supply cords or terminal strips with advanced NCV mode, catering to both low and high voltage situations.
Audible and Visual Alerts
The Breaker Finder provides both audible alerts and visual signals to indicate the presence of AC electric fields and the correct breaker. Bright LEDs enable users to identify breakers in most lighting environments.
One-Button GFCI Tests
The BK120 consists of a Transmitter connected to the electrical outlet or fixture the GFCI test button allows you to test the operation of GFCI outlets. When you press the test button, it creates a simulated ground fault, causing the GFCI to trip and cut off the circuit. This process confirms that the GFCI’s internal mechanisms are working correctly and can quickly respond to real ground faults. Regularly testing GFCIs is imperative for maintaining safety in areas where electrical devices are used.
