‎Klein Tools ET310 AC Circuit Breaker Finder, Electric Tester and Voltage Tester with Integrated GFCI Outlet Tester

Mostly works as intended. Circuit tester works well. Sometimes trying to match breaker to circuit challenging. But that could be a wiring issue. Prevents a lot of leg work running from outlet to breaker box. Would buy again.

Several people have lived in our home and done renovations over the years. There was no way to figure out the electrical panel. I discovered this and gave it a try! It worked great. Watch videos before using it. Now I need to share it with someone who needs to identify their electrical circuits.

This circuit breaker identifier is very easy to use. It not only identifies a circuit breaker but also provides wiring information. It indicates visually and audibly when identifying circuits. Visually when checking circuit wiring correctness. It will indicate faults in wiring visually. This device is a great addition to a handyman’s toolbox as well as the professional electrician.

I found this device very helpful in the circuit tracing in my 1920 house. It worked for me and the video’s posted were helpful too. It has helped this novice in accurately providing a clear picture of the outlets and switches in my house. I was able to make a detailed drawing with the outlets and switches in this old house to assist me in where to place space heaters safely. I found the kitchen outlets were on a circuit breaker by themselves which was helpful. It accurately found the correct circuit breakers for each outlet. I would love to have the extra accessory of the light bulb outlet adapter but it was not easily attached to the order or it was too expensive to add on. And why would I need to buy four of them? It comes with the 9V battery, and the addition of one adapter in the package would make it a sweet deal, and a notch above the rest. I highly recommend this product.

This electrical tool is easy to use and is very accurate. Battery life is outstanding and tge tools is very durable and useful for finding an electrical circuit.

Well pleased with ease of use and accuracy

This product is tops, it actually does what is intended. Finding a circuit somtimes is a challenge. Especially when the panel is not labeled, this is the tool for that. Just plug in the circuit checker and go to panel and hear the tone change when it identifies what belongs where.

This unit works perfectly. I was able to identify the circuit breakers associated with multiple outlets throughout my house and garage. My neighbor has since borrowed it. He accomplished the same thing, and he is not usually very good at these types of things. Don’t do like I did and first buy a cheap version of this tool just to send it back, because they just don’t work reliably. Just spend the money on one of these and get the job done right with confidence.

This was a gift for my fiance because he has learned to do all the electrical work in our house. This tool has made his life a lot easier for trying to figure out what breakers connect to what areas of the house because the electrical circuits are a mess!

I recently moved our kitchen from one part of the house to another room. This tool helped track wiring and identify and organize all the existing circuits, and create new ones where needed. It allowed me to allocate circuits to specific parts of the new kitchen more effectively. It’s also helped me locate where all of the existing circuits’ receptacles and fixtures are elsewhere in the house. I didn’t build the house but have made many changes over the years – and the builder did not do things to code. With this tool, I could do the work myself, without help.

I was really wanting the breaker finder but opted for the kit because I wanted a dedicated circuit tester as a backup to my Gardner Bender wire strippers that have a built-in tester.The breaker finder works brilliantly! It is accurate and very easy to use. Absolutely love this tool.The circuit tester in mediocre, unfortunately. It seems to require direct contact with a wire to sense current. My old GB wire strippers can sense current from a couple of inches away and seems more reliable.If you want a breaker finder and already have a circuit tester, I’d suggest skipping the kit and buying just the breaker finder.

It worked like a charm. Took all the guess work out. I am happy to own one now.

I’ve used Klein Tools for years in the Telco Industry, but they make great electrician gear, too. Kept blowing a GFCI outlet in my garage, and believed the issue was an outlet outside my garage. NOPE! The GFCI circuit turned out to be crossed with a circuit to my office. The electrician had run BOTH circuits through another outlet and had cross wired the neutral through it. Luckily, I used the voltage detector and cross wire indicator. The toner function showed me what breakers were actually crossed and once I flipped the breakers, I was able to straighten the whole mess out. I still have my original problem with a dead outside outlet, but it doesn’t show up in the breaker box.

Works amazingly. Makes changing outlets so much faster and easier. Only issue is that it will detect wrong outlets if the feed line is close to that breaker, so always verify twice before tripping breakers.

If your home is like many the panel labels can be faded/hard to read or perhaps not accurate. This tool is great for validating panel labelling as well as checking your work and testing GFI outlets.

I am so happy I discovered this from youtube videos. I’ve already used it a half a dozen times to fix some badly mapped out outlets. This is a great start for DIYers like myself. The plug also acting as a current detector is great to make sure you’re working when it’s safe to do so.

ectrical Work. If you plan to do ANY electrical work they buy this tool, it will pay for its self in a single use. You should also get a voltage tester to double check for “live” wires. I have worked on too many half-assed jobs performed by “professionals” to trust anything. These tools will help you ensure that the work is done correctly and safely https://www.amazon.com/Non-Contact-Detector-Klein-Tools-NCVT1P/dp/B099SJ6469/ref=sr_1_5?crid=IFFMVGMJI92T&keywords=klein+circuit+tester&qid=1680875826&s=hi&sprefix=klein+circuit+tester%2Ctools%2C115&sr=1-5

e house in a few hours. I love this thing. I’m able to know exactly which circuit every light and plug is in my house now instead of flipping one and seeing what turns off. Knowing general room/areas is good, but knowing the exact plugs that will turn off with each breaker is awesome. Could have done the whole house a lot quicker with a helper, but I did it myself going back and forth and got the whole house done in a few hours.

a 3 story 40 year old condo they just bought as a fixer-upper… Poor bastard was running up and down stairs like OJ Simpson running from the cops trying to trouble-shoot bad outlets, etc. Bought him this for Xmas and he almost cried when he opened it. Now, I want one! Hey Chris.. Check my wish list damn it! Hook a brother up! I’m damn near sixty and the knees are snapping like big mouth bass on a hot summer day! When I die, you can give it to your brother and be the friggin hero! Come on man, they’re Klein Tools… You cant go wrong!

pping breaker switches. I love when a product meets or exceeds expectations and this Klein AC Circuit Breaker Finder With Integrated GFCI Outlet Tester is that tool. I was needing to update the bathroom plugs and switches. It was great to plug in the transmitter into the outlet then go to the electrical panel and use the receiver to find the correct breaker. You have to pass the receiver over the breakers in the panel first to train the receiver, then make a second pass to locate the correct breaker, the unit starts flashing and beeping at the right breaker switch. For a couple dollars more you can add the accessory kit that usually runs around $15. If you need to change outlets in your place, this tool will make your life easer (who doesn’t need that?).
