Extech - 1218G94EA - CB10 Circuit Breaker Finder, Locates fuses/breakers, Tests receptacles and GFCI circuits, Green,Red

The Extech CB10 makes finding breakers fast and easy with its transmitter‑and‑receiver design. Signal strength indicators are clear, and the controls are simple — perfect for DIYers and pros alike. Build quality is solid, and it works reliably on standard North American circuits. Note: The plug may need a small modification to fit certain outlets, but it’s manageable. Overall, a great value for anyone working with electrical panels.

Our panel labels are no longer accurate following a partial remodel a few years ago, and a service- and panel-upgrade last year. I need to replace an outlet without accidentally shutting down our computers, and the Extech 1218G94EA CB10 Circuit Breaker Finder made it easy to locate the right breaker without shutting anything off first. I've read the reviews of other breaker-finders and their users' difficulty pin-pointing the one correct breaker out of the several (or many) the tool identified. This tool has a sensitivity dial allowing you to manually decrease the sensitivity until it only responds to one breaker as you scan the panel. Since it does not try to adjust itself automatically, you get to tweak the sensitivity up and down until you're confident you've found the right breaker before you shut anythnig off. When you do shut off the breaker you identified, the signal disappears completely, even at full sensitivity, as a confirmation. When you go back to the outlet, the transmitter lights will be off as a second confirmation that the circuit is dead. This is a two-piece tool: A transmitter (which is also a wiring-fault tester and GFCI-protection tester) that you plug into the outlet whose breaker you need to identify; and a receiver/scanning tool that you pass over the breakers on your panel and which beeps and flashes when it finds the transmitter's signal. The transmitter comes with a cheap 9v battery which probably won't last long, and which will likely eventually leak and damage the tool. I'm using mine (hey, I had to try out my new toy!) but I'm going replace it with a high quality battery Alkaline battery very soon. I'd call this a home handyman-/handymaam-level tool for its less rugged construction than what a pro would need and expect, and it's priced to match. No stars off for that - it's the right tool for the market it serves. A pro tool would probably include adapters for a light socket and a set of jumper wires, which I didn't want or need right now. If and when I do, those are hardware store items.

Testei e recomendo

Good working 👍
