Klein ET300 Circuit Breaker Finder Review | How to Find Circuit Breakers Fast!

[@jimwoodmansee]

great how-to...after I watched your video I bought the Klein ET300 and the adapter and I mapped out (in a spreadsheet) my whole house to each outlet and each hard-wired appliance. Then I looked up the wattage of each item we might use in the house in a power-outage and added them to the spreadsheet matched to the correct circuit breaker. I was trying to determine the right size portable generator hooked into our circuit breaker box by the electric company. Playing with different combinations of items turned on at different times of the day I determined that a 8000watt generator would work. Then I added 4 more columns to the spreadsheet; Morning (6:30am-11:30am), Afternoon (11:30am-5:30pm), Evening (5:30pm-9:30pm), and Night (9:30pm-6:30am) and, for each circuit breaker in each time zone I indicated "on" or "off". For the combination I settled on, the Morning used 6960w, Afternoon used 4890w, Evening uses 7987w and Night uses 3559w.

I bought mine around 2008 back when they were orange and about $27.00 and I still have it today. I can't imagine not having it. I bought the addl kit 6 yrs ago and it is awesome. I came here to check the adapter with the two wire clips to connect to bare wires cuz I have never used it before and can't find the directions. Thank you for excellent video. You are like me always making comments about how they should make the product better/safer. Well done.

Thank you so much! I have been looking everywhere to learn how to find the breaker for my smoke detectors. This is a great video that demonstrates how to use the Klein Finder and its accessory kit. It's time to change all the smoke/Co2 detectors in the house and I didn't think I would ever find a way to locate the breaker.

Bought one of these Circuit Breaker Finders, same model, a while ago right after I spent a couple of days at our house, and my MIL's house, doing a whole lot of electrical work. During those two events I was on the phone with my wife on the inside while I was on the breakers outside. "Is that it? ... ok... Is that it? ...ok... Is THAT it? ... ok..." etc. I got one of these a couple of days later and haven't needed it until today. Your video is awesome. It's simple and to the point, and that damn switch was annoying me as well, so thanks for the hint about that. Now that I've seen this video, I'm going to go check out your other videos to see if you have any hints about a GFCI in the master bedroom bathroom shutting off the outlet for the fridge in the garage. ;-)

[@davidhatcher1611]

I've kept one in my bag for probably 5 years use it all the time

[@Subgunman]

Bought the same setup about 17 years ago. Red in color and sold by another major electrical parts supplier. Mine is rated for 110/220 volts. As for the accessory kit it is way overpriced. You can buy most of these adapters at most big box hardware stores for under 8 dollars. They are a great tool that saves time.

[@HerbOMatic]

I just found the accessory kit (another brand but identical) for $9 and posted the link, you got me thinking $15 was a little high, thanks! It does save a ton of time!

[@KefirTView]

Could I use this tool not only to find a breaker switch, but to also locate other lines in a wall for continuity using the clips and the wand? Example: Two different outlets and I want to know if they share a "hot." Can I place the RED on hot (black) and use any neutral in the wall to check further down the run if it's the same hot (black) wire providing power?

[@Hotsparks66]

Just ordered mine, waiting for it to arrive. I hope it works as shown. I purchased an cheap off brand from Harbor Freight. Very unreliable and hard to use. Went right back to the store. Good demonstration.

[@WoodgemanX]

I own both the Klein and HF models. Identical devices, same workers, same factory. I bought the HF model first for $15, picked up the Klein model at the Depot when it was on clearance for $10.

[@zeekflash6924]

Thxs for explaining all 3 , accessories , only videos that I found so far

[@paulseibert6046]

Very helpful. Plus straight and to the point. Thanks

[@jelaniashanti]

What is you get no power to the cables ?

[@jeffgreenfield4174]

A very thin o-ring or small rubber band stretched around the powewr button keeps it from turning on inadvertently and the button can still be pushed, albeit a little firmer, to turn the receiver on and off.

[@SavageVoyageur]

Great explanation of this tool. Thank you very much for this video.

[@BRabbit716]

Can’t use it for 3 phase power

[@TheTriggerhappyhippi]

Thank you my good sir. It’s rough being a greenhorn

[@james77011]

🙈🤦🏿‍♂️ yooo! I was in home Depot today and I was looking at this same kit... Now I have to buy this next time...

[@jcaleca60]

I used to get 100 watt light bulb take the cover off the panel and put my Ampro on each circuit breaker wire I would have the flashing type connected to the bulb you can buy those small little flashes I would put the pigtail with the Flasher but with this tool here you don't have to take the cover off the panel

[@MrMaelstrom07]

Do you know of a breaker finder that could include a clamp to test a non-bare wire? If there's a set of wires that run into a wall, I would like to know which wire is part of which breaker. All I've seen have either the plug-in (like you show), and the bare wire adapter.

[@HerbOMatic]

I don't think so because the transmitter sends a signal down the wire. I don't think an induction (clamp-on) style would work.

[@fauxque5057]

I'm not sure I understand your question but if you are trying to locate say one romex cable running in the attic out of a dozen of them, then yes this tool will pick out a cable from the bunch. Plug in the transmitter and then test each cable separately with the receiver. Lift and separate so you know which cable you are checking. Work through the bunch until it beeps, then do it a few more times to be sure. Then unplug the transmitter and recheck the wire you believe it is. If it no longer beeps you have the right cable.

[@Djloconyc]

How about for a light switch? That the light doesn't work

[@FernandoRodriguez-lh9ft]

I had an issue with the circuit breaker finder. Idk why once I kill the power in the breaker it already indicated, the light in the receiver kept on. That was weird, it already happened twice to me.

[@HerbOMatic]

Sometimes circuits are wired weirdly. Make sure you scan the entire panel, you have to calibrate the receiver to ignore the electrical noise.

[@srira7910]

Dirty electricity, improperly wired neutrals, ground to neutral voltage may be suspect.

[@juanbartolome9744]

Definitely need to get one. I’d probably put some tape or something on those alligator clips but thanks for the review

[@HerbOMatic]

You bet Juan, those clips were a trap!

[@Cam-wi3tp]

got mine today, won't even detect from an outlet 10 feet away, spent an hour running from outlet to outlet, turning off and on. Got it to pick an outlet right next to panel but none of the other outlets in house were detected

[@HerbOMatic]

Must have a defective one, they are usually great!

[@ajsironworks3937]

Super cool. Never seen that before. Thanks for sharing.

[@HerbOMatic]

Thanks! It saves a ton of time.

[@comachocomacho6581]

Hi is still send a signal even there is no power in the outlet? Thanks

[@PoorBoy.22]

No, it has to be live

[@BRabbit716]

The ET 450 dose

[@odeponakayode3798]

Nice episode thanks so much

[@WoodgemanX]

Should've saved the packaging the tester came in, it protects the tester and keeps it from accidently turning on. Since you cut up the packaging, use a small O-ring around the switch, bread tie! Please.

[@tommycollier9172]

Thanks Man

[@generelspaz]

Dude… how has this had so few views! Ringing that bell

[@jondavidmcnabb]

Excellent review and i will be buying on of these because of it!!!

[@HerbOMatic]

Glad you liked it Jon, it's a handy device!

[@minlwin3249]

Thanks.

[@traciemcelroy6391]

lol at all the damn time :) great video

[@metalshopmachines9407]

I don't understand why you need it on a light fixture. Just turn off the switch. Wouldn't that keep you from getting shocked?

[@timothylynch1380]

Sometimes wiring is weird. I’ve seen where some wires in the lighting box are live even though the switch is off. Never guess. One day you’ll be wrong

[@WoodgemanX]

You want to kill power to the switch if you are upgrading the switch or replacing it with a dimmer.

[@jcaleca60]

Put the yelling method was nice I could have yelled at my ex-wife and get away with it😅😅😅

[@WoodgemanX]

Don't take advice from anybody who doesn't know how to open a blister package. Cut around the edges of the package, two sides is enough. I use the packaging the tester came in for storage.

[@willbrake9252]

You can make that for like three bucks

[@srira7910]

It's a shame Klien Tool's quality has gotten worse over the years. The insulator falling off the Alligator Clip is a prime example. We stopped buying their products...

[@HerbOMatic]

Who do you recommend?

[@zebiosogliani7132]

Low precision. It's very inaccurate
