Cool Tool Alert: The Klein Circuit Breaker Finder/GFCI Tester at Last Best Tool

[@Zeric1]

For one's own home, it pays (over and over!) to take the time to fully document all the circuits. Several years ago I went through my entire house and documented what every one of my 35 breakers connects to- every single outlet, light, appliance, HVAC, etc. It isn't difficult, it just requires being organized, and only has to be done once. Now when ever I need to shut off an outlet or fixture, not only do I know which breaker it is, I also know what other outlets/lights/etc will also lose power so there are no surprises. Using a Breaker Finder helps in documenting, but isn't strictly needed. Additionally, knowing exactly what is on each branch circuit allows one to more easily assess the loading.

[@Cheka__]

Agree 100%. I can't stand when I'm in a new home and I find that the circuit breaker panel is labeled incorrectly and/or incompletely. Even if you don't care about future users needing to know the correct layout, why the heck wouldn't you do it for yourself. Idk.

[@littlejimmy7402]

I live in an area of the country with some old homes and loose regulations. I live in a home that's not that old (50ish), but dagnab it. The amount of poorly planned and executed "upgrades", flips, alarm systems, etc. The electrical layout of some of these homes is the obvious work of Clark Griswold. Expect some frustration.

[@moxxy3565]

Pfft why bother when you can used the tried and true method of trying every single circuit and yelling "IS IT STILL ON?!"

[@philstuf]

@5:22 Sold. I need this now.

[@Pluto_ice]

One important safety step I haven’t heard mentioned in the review videos I’ve watched is to check that there is no voltage at the outlet/switch/wires that you’re working on AFTER you’ve turned off the circuit breaker. In rare instances you may have a short circuit where the wired from more than one circuit breaker come into contact due to worn insulation or incorrect wiring.

[@CarlosGarcia-ls4hn]

Exactly. That is why you should test both receptacles to test for voltage and not take it for granted that the single breaker controls both receptacles.

[@stevehulbert1836]

Very nice video. Very informative and to the point. You also have the right voice and speed for a good video. Thank you

[@carlosquiahua1614]

One the best video thank you brother for explain how to use this tool

[@nodak81]

Thanks for the demo! Does it come with any accessories? Klein's less sophisticated model comes with a couple of adapters that allow you to plug into a light bulb socket. Worth having.

[@lastbesttool]

Mine came with nothing but the two parts and instructions. No pouch that I remember. But adapters are easy to find, and often if included are the cheapest available. But for quick use, it makes sense.

[@leedchristensen]

Use a radio so you can hear if it’s off instead a light that you can’t see. The Sperry cheaper one has a tone in the outlet transmitter so you can hear it.

[@ChrisBranleh]

I was actually thinking of doing this with a tiny radio but im having a hard time finding a cheap radio with aC power. I think for someone who doesnt have the GFCI outlet tripper (myself right now), this could be a good value but it is definitely expensive. I imagine someone who does home maintenance / handyman work this could be very useful so theyre not tripping various breakers that aren't documented properly while tenets are present and using the electricity

[@scraplifetrashtocash4551]

😂😂😂. That don't let u know if there is a open end on sockets. U still could have a open hot with no ground. Don't give information on shit u don't understand. Go wash the dishes and laundry

Great video and demo. Thanks

[@LilasTools]

Awesome! I’m getting one for sure!

[@yuqin405]

Hello, nice demo, thanks. My question is, when you plug the GFCI tester into the wall outlet, do you press the button before you scan the panel with the circuit break finder?

[@iceinyourveins-rn7em]

No. There is no need to do that. You do have to plug it into the outlet first (as he mentioned in the video) then turn the wand on. Then your ready to scan your breakers.

[@DAT-TEXAS-DUDE]

​@@iceinyourveins-rn7em It has to be calibrated first buddy then you scan every breaker to find the breaker to outlet.

[@Coodeville]

Got one today. Love it!

[@aguycalledlucas]

Which one

[@egbluesuede1220]

I love having this one. Makes me look so smart but it's really simple to use.

[@petebusch9069]

Thank you for not painting your panel cover to the wall.

[@ThomasStgermain-n7z]

Does this work with the glass fuse type breakers ?

[@CarlosGarcia-ls4hn]

If you have a wall outlet with two 120 volt receptacles, you should not assume that both run on the same circuit. I would test both, otherwise, you might get shocked into the next county.

[@branned]

Way cool👍👍

[@RichardBaileyrichoncode]

Can i use this to test an outlet that is off? I want to find the breaker.

[@dustinbird2090]

If the outlet has voltage being supplied to it, then yes, the transmitter will be able to send a signal and be picked up on by the receiver.

[@sp00linhard20]

I’m looking for this feature too

[@dds425]

Can work in 220v? What's the battery size?

[@djliserio994]

Does this work as a non contact tester ?

[@DA-rf7zj]

Nice video and potentially nice tool. My concern would be the tandem breakers I see in you service panel. Are they multiwire branch circuits? My guess is you could get close, but still have to turn off multiple breakers before finding the right one. And yes, I'm not fan of multiwire branch circuits.

[@marcus05011993]

I just bought this tool because the house I live in was all wired funky so I wanted to see what outlets were on what circuit I do have a couple multi wire circuits like you suggested and it does well with them if I put it on the top half versus the bottom half I get different readings so it still works well for that

[@kechickdon5545]

Hi.. is it possible to use an adapter due to different socket outlet?

[@robw9435]

Yes. You can even buy a light socket adapter so you can test lamps, light fixtures, etc.

[@jessihawkins9116]

no it is not possible

[@jimb7922]

How would you find the breaker for a 220 volt outlet ?

[@nestoranchez4330]

Best review!!!!

[@raulchavarria7446]

If the GFCI is not working, will it still send a signal?

[@raulchavarria7446]

I’ll answer my own question. No, it doesn’t work if the GFCI is not working.

[@jessesanchez2648]

Nice

[@mikedeo5143]

I have tandem 15 and 20 amp breakers this doesn't work with them

[@kechickdon5545]

Is it works for AC240V..?

[@lastbesttool]

I do not believe it does due to the outlet transmitter.

[@mayorb3366]

@@lastbesttool I work with 230V usually from a relay or an electro-mechanical timer, (line-load-line-load). I have the test lead adapter that the transmitter plugs in to. Both "line" terminals are hot (115v) from breaker. Can I (do I need to) connect a lead to one line, and the other to a neutral if there's one nearby? Don't want to try it yet, in case I blow up my meter!

[@jessihawkins9116]

@@mayorb3366does it work or not

[@sylkelster]

@@mayorb3366 As long as the transmitter receives 120V, there is no reason this would not work. The neutral is not required to be in the same bundle as the tracer wire. A grounding wire would also work in place of the neutral (obviously) for testing purposes.

[@GOLFNBADSTYLE]

Does that work if the outlet does not show hot

[@sylkelster]

No. Transmitter requires receptacle power to be on.

[@MarkKuehnel]

Hate loaning out tools. Somehow the person borrowing them think they are on permanent loan then i have to go retrieve it.

[@jackinfo121]

Hi. Would this work in the UK 230V?

[@jessihawkins9116]

it wouldn’t. u limey crumpet stuffers are on your own 🤨

[@sylkelster]

Maybe once, then room fills with oddly pleasing burnt electrical magic smoke.

[@Margalus]

The battery compartment is annoying though. Instead of having a simple snap cap, you have to use a small screwdriver to replace the batter in the receiver. And since it doesn't get used all the time I like to remove the battery when not in use.

[@damienbender213]

Wahhhh!!🍼

[@SergioRodriguez-de9qu]

Do you know the range of the transmitter

[@lastbesttool]

No clue but since it's a circuit signal, I imagine anything inside all but the largest building is within it's range.

[@VideoGameRoom32]

I don't know what's happening but when I did this I turned off the breaker when it detected red but the power was still on the transmitter and the rest of that room. Was it a false read?

[@Jimmyjimjimjim]

I got one and it’s hit and miss in a big building. I service grocery stores and never really works.

[@platoscavealum902]

👍

[@Tyani-sz6cg]

Question. Can I use this to find all the outlets/switches on a circuit?

[@iceinyourveins-rn7em]

Yes, but for the switches are a bit more involved. I would highly recommend that you get an Electrician to do those. You would also have to buy the accessory kit that comes with a few adapters.

[@kamranahmad6848]

Small thing you made a big story how KZbin

[@นนทกานต์มูลสง่า]

Is this 110 or220 v?

[@lastbesttool]

110v due to the transmitter needing a standard outlet.

try it the furthest circuit from the panel. Then let's see what it does.

[@ROJINEGROSFC2024]

Doesn't work correctly i have one and give me the wrong braker

[@lastbesttool]

That is really odd since there is a tone or signal between the transmitter and receiver that is outside normal circuit noise. So it should be impossible to indicate the wrong breaker. Maybe no breaker, but not the wrong one. That's like the wrong telephone ringing when you call a number. But I guess somehow it could happen. Thanks for the comment.

[@sylkelster]

@@lastbesttool You answered this in the video. The tracer has to develop a learning curve and must be scanned at least twice for calibration, since every odd breaker set and every even breaker set share common buss bars. My first pass indicated three separate breakers.

[@crowntotheundergroud]

@@lastbesttoolmine gives me false positives on 2 or 3 circuits without the transmitter even plugged in. Then it gave me 2 false positives in addition to those 3 circuits when it actually was plugged in. Yes, I’ve scanned both rows several times to calibrate it. I’m not sure what the issue is, but it’s being thrown off by something. Piece of junk

[@NorthShore2]

Can a test a switch also or just an outlet?

[@dkraft]

switch works too!
