Questions & Answers

will this find the circuit breaker is there is no power to the outlet?

will this find the circuit breaker is there is no power to the outlet?
Asked by: Terry
No, it cannot because the transmitter requires the outlet voltage to energize its circuitry.

If I don't have any power in my outlet, would this device detect which breaker it is hooked up to in the control panel?
Asked by: Helpme
If you don’t have any power, then the circuit breaker switch is flipped or you have a broken line. This will only work if the line is unbroken and the breaker is on.

Not sure how to ask this, but how the heck can so many people give a 1 and it is not trusting and so many get a 5 and works fine???? I get the switch problem and I love the guy's fix. I get also the issue that could happen trying to learn the panel. It is driving me crazy, I cannot trust anything out here on this matter.
Asked by: AL9000
First off, this is not a $$$ circuit analyzer. Take your time and be methodical. It works well for what it is.

Digital Circuit Breaker Finder is rated 3.7 out of 5 by 184.

You can't store it or carry it anywhere that you might breathe on the button - it turns on and beeps instantly. You have to hold it for 3 seconds to shut it off. The thing works as advertised but is useless unless you want to unscrew and remove the battery cover and battery every time your done using it, then replace when needed...? It supposedly has an auto off, but I tried storing it in my bag with my other new Klein tester and it kept beeping at the slightest touch... RETURNING IT along with my Klein non-contact voltage tester, which after one day intermittently will not beep when voltage is located. In fact, I'm returning all of my newly purchased Klein tools - not impressed.

Let me start by saying this unit works great if you use it correctly and follow the directions. It would at best identify two breakers side by side as the target but I'm fine with that...it's better than having to test all 50 breakers to find the one you need! I agree with the reviews about the on-off switch being much too sensitive, but there is an easy fix! Take a small o-ring and insert it under the lip of the switch, this secures it from being turned on in the tool bag but still allows regular operation (see photo attached) This idea cures the problem and makes this unit worth the money.

I have worked electrical work for decades, and this did nothing as advertised. Tried with the receiver in both horizontal and vertical orientation. Tested on circuit I know which breaker was attached to the outlet, and NOTHING. It did indicate another breaker, which I turned off just to double check. No beep when breaker opened but the outlet was still hot.

It does give some false readings, but all in all it saves valueable time in panels without any markings. It sure beats a loud radio and flipping every breaker till you find the right one to shut it off. It does have a sensitive on button.
