Extech CB10 Circuit Breaker Finder - 1218G94EA

joe: This device works better than I expected..... The secret weapon is the adjustable sensitivity setting.... I give it a 5 for ease of use and near consistent accuracy.... The downside is the on/off, sensitivity combo switch... The switch works well but is not very sturdy. Reminds me of a on/off volume control on a 20th century 5 dollar transistor radio... If you buy it, treat it with care.

Thomas S.: Found every circuit that wasn't marked.

J Engineer: Using this to inspect my own house for issues. Was a big help tracking down which outlets are on each breaker. Found the breaker for each room, then shut off the breaker and used the voltage detector to check each outlet. Found several that are on wrong or weird circuits. It's not fun when you think everything in a room is off, but the one outlet you're working on is on a different circuit and still live.

For some reason, I was sometimes getting a positive reading on two breakers, but there's a very real possibility it's due to the wiring in my house, or I just needed to adjust the meter sensitivity a little more. Didn't spend much time on it because I knew the other breaker was not the one I was looking for. I'll try it again sometime and update

Also plan on using in the attic to locate and identify wires that are buried under blow in insulation. Will update once I have time to tackle that project.

Haven't used the continuity tester yet, but should come in handy.

JRobert: 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...

Gerry Davis: Purchased kit for personal use works well for home use would stepping up to another kit if using it for work. Dislike to handheld voltage testor with the light, it has no sound just the light when it detects voltage. I have similar models with sound and lights I find them better

Shawn: Very effective tool, I use it on almost every repair call.

It made me look like a pro when I labeled all the sub panels for a commercial warehousing customer of mine who berths hundreds of food trucks boats and RV's. When they need to know where a breaker is in one of their 9 panels they can find it because they are all labeled now at the receptacles.
It works for two and three leg circuits without neutral legs better than I thought it would. I used alligator clip jumper wires and pins to connect the plug to the various twist lock and range receptacles that the food trucks plug into for the night. It is a little hazardous to have open hot wires using alligator clips, but it works safely and well well with a little caution and a vigilant helper.

I am very happy. I have also used it to locate GFI feeds and test GFCI receptacles. It is a good tool and a great price.

It is not a hard core unit in the long run, but it is not crummy cheap either. I am a professional repair contractor and although I am not destructively hard, am very hard on my gear in normal use, electrical work is a rough discipline. I drop things a lot, and I use it up, burn it out, and play it...
