Review: رائع - احنا شركة لصيانة مضخات المياه و التحلية الجهاز ممتاز لتتبع الاسلاك القديمة Review: This is worth it! - This tool is a necessity for anyone working with electricity as it also works on live circuits. It will help you find hidden wires just about anywhere. One of the best cases was trying to find a ~20 year old buried cable outdoors where trees have grown up and the people that originally buried it must have been drunk because the line went in very odd multiple directions and power didn’t come out the other end about 300’ away. Turns out there was a buried splice in the ground about 1.5’ down where someone had spliced the line (went somewhere else into the back 40 🙄) only taped the connection (no marrets) and tried to encase it all in fiberglass 😂 I would never have found that without this tool. If you wanted to install lag bolts into a wall, the price of this tool for a one time use would be worth the cost to make sure a wire wasn’t in the way or you’d instantly be into more money to fix it if you needed to call an electrician to install a new wire. ## Features - RELIABLE CIRCUIT TRACING: The Advanced Circuit Tracer Kit ensures dependable tracing of energized or non-energized breakers, fuses, and wires for accurate electrical identification - ADJUSTABLE SENSITIVITY: Easily modify receiver sensitivity to detect transmitted signals through various materials like drywall, cement block, or underground, enhancing tracing capabilities - VERSATILE APPLICATIONS: Trace wires, conduit, pipes, or isolate a single wire within a bundle, making it suitable for a wide range of electrical tracing tasks ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09XG38XLP | | Best Sellers Rank | #86,395 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #126 in Circuit Testers | | Brand | KLEIN TOOLS | | Brand Name | KLEIN TOOLS | | Color | Multi | | Colour | Multi | | Compatible Devices | Transmitter, Receiver, Blade and ground prongs, Alligator clips, 3-Foot and 20-Foot lead adapters, AC plug leads, Batteries, Instructions, Carrying case | | Customer Reviews | 4.7 out of 5 stars 1,481 Reviews | | Global Trade Identification Number | 00092644693380 | | Included Components | Advanced Circuit Tracer Kit | | Item Dimensions | 40.9 x 32.4 x 10.2 centimeters | | Item Type Name | Advanced Circuit Tracer Kit | | Item Weight | 2 Pounds | | Item dimensions L x W x H | 40.9 x 32.4 x 10.2 centimeters | | Item weight | 2 Pounds | | Manufacturer | KLEIN TOOLS | | Maximum Operating Voltage | 480 Volts | | Measurement Type | Voltmeter and Frequency Meter | | Minimum Operating Voltage | 12 Volts | | Model | ET450 | | Part Number | ET450 | | Power Source | Battery Powered | | Power source | Battery Powered | | Specification Met | [Inferred] Meets Certain Specifications | | Style | Circuit Testers | | Style Name | Circuit Testers | | UPC | 092644693380 | | Upper Temperature Rating | 50 Degrees Celsius | ## Product Details - **Brand:** KLEIN TOOLS - **Colour:** Multi - **Item weight:** 2 Pounds - **Power source:** Battery Powered - **Style:** Circuit Testers ## Images ![Advanced Circuit Breaker Finder and Wire Tracer Kit for Energized and Non-Energized Breakers, Fuses, and Wires ET450 - Image 1](https://m.media-amazon.com/images/I/61vajIoFLoL.jpg) ## Questions & Answers **Q: Can this find a dead short?** A: Depends on the situation. It’s more for finding the cable pathway, but could help find a dead short. **Q: Can this unit trace wires that are in flex?** A: Yes **Q: Can I trace from a light fixture back to a switch? (I can not find how to turn on a few lights in my new house)** A: this tracer work's better on energized circuits but will also work with de-energized circuits. if your light is not energized, then hook up the transmitter to it and then use the receiver to follow the wire through walls and ceilings to find your switch. You may have to set the detection level higher on the receiver for this use. **Q: Will this tracer generate an audible tone when connected to 14/2 speaker wire?** A: Don’t know. I’m deaf and just look at the visual readout. ## Customer Reviews ### ⭐⭐⭐⭐⭐ رائع *by M***D on 22 January 2026* احنا شركة لصيانة مضخات المياه و التحلية الجهاز ممتاز لتتبع الاسلاك القديمة ### ⭐⭐⭐⭐⭐ This is worth it! *by G***Y on 1 February 2025* This tool is a necessity for anyone working with electricity as it also works on live circuits.

Muy sensible y ajustable. Utiliza 10 Baterias 2AA *by C***M on 8 February 2024* Lo compre porque requiero un equipo que sea capaz de detectar y rastrear cables enterrados o en paredes, ademas de poder rastrear interruptores. Encontre este equipo, que si bien se puede utilizar para cosas caseras, por su precio y sensibilidad es mas bien para condiciones y trabajos comerciales o industriales. La sensibilidad es ajustable, pues como el generador de señal es muy potente, la señal puede difuminarse en interruptores o zonas adyacentes, pero para eso tiene un metodo de conexion que permite eliminar ligeramente la amplia distribucion de señal. El equipo se ve, se siente y tiene funciones avanzadas, es muy robusto, grande y a la vez facil de utilizar. Viene con varios accesorios para conectar el generador de señal a diferentes necesidades y su instructivo de uso es muy sencillo en caso que no hayas utilizado algun equipo similar. Lo que mas me gusto es que la potencia de señal es muy fuerte, tanto que pude rastrear cables hasta unos 50 cm de distancia y en otras condiciones hasta casi 1 metro. Lo que me gusto tambien es su robustes, es de uso rudo y de uso sencillo. Lo que no me gusto es la gran cantidad de baterias que utiliza, aunque lo usare con baterias recargables, viene con 10 baterias 2AA incluidas. Lo que no me gusto es que la sensibilidad sea ajustable manualmente y no de forma automatica segun se vaya acercando o alejando del rastreo objetivo. Pero en terminos generales estoy muy satisfecho con este equipo y definitivamente lo recomiendo. ## Frequently Bought Together - Klein Tools ET450 Advanced Circuit Breaker Finder and Wire Tracer Kit for Energized and Non-Energized Breakers, Fuses, and Wires - Klein Tools RT390 Circuit Analyzer with Large LCD, Identifies Wiring Faults, GFCI and AFCI Tester, Voltage Drop, Displays Trip Time - Klein Tools 69411 Circuit Breaker Finder Accessory Kit, Circuit Breaker Leads and Adapters --- ## 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.jp/products/646700923-advanced-circuit-breaker-finder-and-wire-tracer-kit-for-energized](https://www.desertcart.jp/products/646700923-advanced-circuit-breaker-finder-and-wire-tracer-kit-for-energized) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-17*
