Klein Tools ET300 Digital Circuit Breaker Finder

Excelente herramienta no se induce como otras Fácil deUsar

The first time you use it, you are not too sure if it is reading the correct breakers, but after you use it a few times, you get the hang of how to align it with the breakers, and then it works like a charm. I am an electrician and have used several of these circuit-locating devices, and this one is the best that I have used in this price range. You can easily spend double the money on other units and get no better performance for the extra cost. The biggest downside, as others have mentioned, is that the location of the on button is poorly thought out - it is too easy to accidentally turn it on. I solved this by keeping the unit in a hard case rather than soft.

This is an AMAZING tool! I just returned the Sherry CS61200P for its inability to isolate the circuit AND giving way too many false positives (see my review on that tool).This tool (Klein ET300) is a simply, but highly effective tool.Before I discuss its use, let’s first look at the benefit that we are seeking with a circuit breaker finder: we want it to identify THE circuit breaker in question AND NOT identify ANY others (this is called a “false positive”). In short, with this type of tool, you are seeking CONFIDENCE. This tool delivers.Thistooldoes that 100% of the time and with ease. It bears repeating to list the instructions explicitly:1) Plug the “signaling device” into the desired outlet (you can also test lights and wires with adapters).2) Take the “finder” to your control panel.3) Starting atone row of breakers at the first one, slide the finder right behind the breaker’s handle with the finder PERPENDICULAR to the breakers.4) Slide it down that row and do the same for the other row(s).5) You are doing this for the finder to “learn” the panel. IGNORE any sounds during this part of the test.6) Then, do steps 3 & 4 AGAIN.7) During this “slide” the finder WILL locate the ONE breaker in question — with a beep and a large green arrow.8) If someone is helping you, ask them to watch the red light on the signaling device while you turn the circuit breaker off to confirm that it is the right breaker. It will be.The accuracy, the ability to not show false positives, the ease of use of this tool just blows me away. It is the FIRST time that I’ve ever used one of these tools with 100% confidence. It is that good!NOTE: My control panel is a Square D QO panel. I’m assuming that the tool will work similarly on other breakers & panels.Again, highly recommended, no reservations whatsoever, 100% satisfied.

Lo primero, la idea es buenísima para localizar cualquier automático o paso por cajas de registro.Lo malo, las clavijas del enchufe es sistema americano, solucionable con un adaptador, lo verdaderamente malo para el sistema europeo es que el funcionamiento es para voltajes entre 90 y 120 V.C.A. lo que lo hace NO VALIDO para ESPAÑA

As a certified Journeyman electrician working in residential homes, you run into a lot of old panels that aren’t labelled and finding the right breaker can be a nuisance especially if you have to go up and down the stairs multiple times, so after trying this tool out, you realize how magical this tool can be. It does exactly what it should do. The only downfall is the button is very sensitive so I use a twist tie around the button when I’m done to prevent it from continuously going off in my bag. But overall it works great! Well worth the money!
