Klein Tools Digital Circuit Breaker Finder with GFCI Outlet Tester, Model ET310
The Klein Tools ET310 is the go-to circuit breaker finder for professional electricians and contractors who need to work fast and accurately on the job site. Whether you're tracing circuits in a residential panel, commissioning a new build, or troubleshooting a service call, the ET310 eliminates the guesswork — no more flipping breakers one by one or calling for a second set of hands. The integrated GFCI outlet tester adds even more value, letting you verify outlet wiring and GFCI protection in seconds without swapping tools. Built for the demands of daily trade use, this is a reliable two-in-one solution that saves time and reduces callbacks.
Key Features
| Digital Circuit Breaker Finder | Quickly locates the correct breaker in a panel without needing a second person — transmitter plugs into the outlet while the receiver scans the panel. |
| Integrated GFCI Outlet Tester | Built into the transmitter — tests for correct wiring, open ground, open neutral, open hot, hot/ground reverse, and hot/neutral reverse conditions. |
| LED Indicator on Receiver | Bright LED flashes and audible beep confirm when the correct breaker is identified, even in noisy or dimly lit panel rooms. |
| Works on Live Circuits | Operates on energized circuits — no need to de-energize the panel or disconnect loads before tracing. |
| Two-Piece Transmitter & Receiver Design | Compact, ergonomic units that are easy to carry and use solo — ideal for service electricians working alone. |
