Review: Works through walls too - I just bought this to use in my older house and it has worked great for finding the breakers and even wires in the wall! I find for the walls it can be a little hard to trace as I feel like the wires have to be within 1-1.5" deep with the sensitivity maxed out and you can loose the signal being as little as 1/4" off from the trail, but it totally works and let me trace a few wonky paths so I could figure out exactly where the wire was moving in my walls and even to a buried junction box. I also really like the manual adjustment since it lets me hone in the breaker real quick and I don't have to scan the breaker like you see with the auto-adjusting ones. I just go to the breaker on about "half" sensitivity, move fast, and when I hear the beep I just drop it to lowest immediately and find it every time. Also due to the manual aspect of it, it let me figure out that a circuit was being served by 2 breakers and tracing which wire went where within the 14/3 wire sleeve itself since I could turn the sensitivity down so low. The socket tester works well too from the few tries. Only real issue I noticed is if you have any of the circuit based dimmers that basically everyone uses now since LED lights need them for dimming, it'll also send a signal in the line that this can pick up. It's real obvious though as it beeps much faster and sounds funny compared to how the device normally works, so either just ignore it and follow the normal beeps or turn off the light, surge protector, etc. Great device and wish I had one sooner to figure out all this weird wiring and no constant breaker switching either! Review: Superb tool for solving basic home wiring issues - This has helped me unravel the mysteries of my house wiring. You plug the transmitter end into an outlet (three prong) and go hunting for the right breaker with the sniffer. You can buy adapters to plug into light sockets and even alligator clips to attach the transmitter to bare wires if you are feeling bold. The tool has a sensitivity knob on the sniffer. This is the part that you get a feel for when using the tool. If you have the sensitivity too high, it's difficult to identify the exact right breaker within the breaker panel. The trick is to lower the sensitivity while you are sniffing until it only beeps when you hover over a single breaker. Bear in mind there is a proper orientation indicated on the end of the sniffer. Now I have one of these, I wouldn't be without it. It's really useful and as you get better with it, you can use it for tracing wires and all sorts of things to get you out of a bind. Highly recommended. ## Features - ACCURATE BREAKER IDENTIFICATION: Eliminate the guesswork and stop running back and forth to the service panel. The transmitter and receiver work together to pinpoint the exact circuit breaker or fuse protecting a specific outlet without cutting power. - GFCI RECEPTACLE TESTING: Verify the safety of your home or job site with the integrated socket tester. It features a simple light-coded sequence to diagnose common wiring faults like open grounds, reversed polarities, and missing neutrals instantly. - NON-CONTACT VOLTAGE DETECTION: Stay safe by detecting live AC voltage from 100V to 600V without ever making physical contact. The bright LED indicator and audible beeper alert you to the presence of power in wires, outlets, and light fixtures. - ADJUSTABLE SENSITIVITY CONTROL: Fine-tune your search with the variable sensitivity dial on the receiver. This allows you to differentiate between closely packed breakers, ensuring you find the right one the first time, even in crowded panels. - COMPLETE PROFESSIONAL BUNDLE: Get to work immediately with everything included in one rugged kit. This versatile set comes with the transmitter, receiver, 9V battery, and a convenient storage case to keep your diagnostic tools organized and protected. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001AGVS8Q | | Best Sellers Rank | #222,031 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #326 in Circuit Testers | | Brand Name | Extech | | Color | Green | | Customer Reviews | 4.4 4.4 out of 5 stars (2,853) | | Global Trade Identification Number | 00793950401101 | | Included Components | 3 Electrical Troubleshooting tools | | Item Dimensions | 6.4 x 2.2 x 1.5 inches | | Item Weight | 0.02 Kilograms | | Manufacturer | Extech | | Measurement Type | Ohmmeter, Voltmeter, Multimeter, Ammeter, or LCR Meter | | Minimum Operating Voltage | 100 Volts (AC) | | Model | CB10-Kit | | Part Number | 1218G95EA | | Power Source | Battery Powered | | Specification Met | CE, UL | | Style Name | CB10-KIT | | UPC | 793950401101 | | Unit Count | 1.0 Count | | Warranty Description | 1 Year | ## Product Details - **Brand:** Extech - **Color:** Green - **Item Weight:** 0.02 Kilograms - **Power Source:** Battery Powered - **Style:** CB10-KIT ## Images ![Extech CB10-KIT Electrical Troubleshooting Kit: 3-in-1 Circuit Breaker Finder, GFCI Receptacle Tester, and Non-Contact AC Voltage Detector - Professional Home & Commercial Electrical Diagnostic Set - Image 1](https://m.media-amazon.com/images/I/91LxHoLhSyL.jpg) ![Extech CB10-KIT Electrical Troubleshooting Kit: 3-in-1 Circuit Breaker Finder, GFCI Receptacle Tester, and Non-Contact AC Voltage Detector - Professional Home & Commercial Electrical Diagnostic Set - Image 2](https://m.media-amazon.com/images/I/810pNlC5wZL.jpg) ![Extech CB10-KIT Electrical Troubleshooting Kit: 3-in-1 Circuit Breaker Finder, GFCI Receptacle Tester, and Non-Contact AC Voltage Detector - Professional Home & Commercial Electrical Diagnostic Set - Image 3](https://m.media-amazon.com/images/I/6185NMjCDBL.jpg) ![Extech CB10-KIT Electrical Troubleshooting Kit: 3-in-1 Circuit Breaker Finder, GFCI Receptacle Tester, and Non-Contact AC Voltage Detector - Professional Home & Commercial Electrical Diagnostic Set - Image 4](https://m.media-amazon.com/images/I/41oy7xCGtwL.jpg) ![Extech CB10-KIT Electrical Troubleshooting Kit: 3-in-1 Circuit Breaker Finder, GFCI Receptacle Tester, and Non-Contact AC Voltage Detector - Professional Home & Commercial Electrical Diagnostic Set - Image 5](https://m.media-amazon.com/images/I/71yNV2cLUdL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works through walls too *by D***D on April 5, 2024* I just bought this to use in my older house and it has worked great for finding the breakers and even wires in the wall!

EXTECH is still a quality product for the home handyman to the everyday residential grade pro electrician but for high dollar pro grade commercial / industrial or / institutional electricians who wire high rises / schools / malls / hospitals and such this unit may be a little lacking in features or quality. if you need a higher quality grade circuit breaker tester I recommend or prefer brands like FLUKE / KLEIN / TRIPLETT / or AMPROBE .this again is just my personal opinion though so please remember that when making your final purchase decision. ............................. here are the things I like about this unit. . (thing one) it has a plug unit that tests wiring polarity issues with colored L.E.D lights. (thing two) it tests GFCI outlets with the red button on top of the plug . (THING THREE) it finds or traces breakers in your panel and matches them to the circuit that the green plug unit is connected to . ..............................these are the things I personally don't like about this device. (thing one) its iffy looking build quality especially on the sensor wand. (thing two) the fact that the green plug unit doesn't beep when plugged in unlike similar SPERRY TESTORS that I have where the plug unit beeps and has a flashing red L.E.D light on the front these features obviously are not 100 percent necessary but they do help and make a minor difference but one thing to understand is my SPERRY TESTORS do not test receptacle polarity. (thing three) the sensitivity wheel on the wand unit seems weak and doesn't seem to have an equal or effiecient adjustment range across its entre range of adjustability. in summation this is not a bad unit it gets the job done but it does have some very minor hindering issues that finicky users or ultra high end professional electricians might find lacking. . ## Frequently Bought Together - Extech - 1218G95EA CB10-Kit Handy Electrical Troubleshooting Kit with 5 Functions - Southwire 58292240 60030S Circuit Breaker Finder Adapter/Accessory Kit; Includes Alligator Clips and Light Bulb Circuit Adapter (Compatible with Southwire 's 41210S Circuit Breaker Finder) - Klein Tools ET310 AC Circuit Breaker Finder, Electric Tester and Voltage Tester with Integrated GFCI Outlet Tester --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/10938761-extech-cb10-kit-electrical-troubleshooting-kit-3-in-1-circuit](https://www.desertcart.sk/products/10938761-extech-cb10-kit-electrical-troubleshooting-kit-3-in-1-circuit) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-07*
