desertcart.co.jp: Klein Tools Digital Circuit Breaker Finder with GFCI Outlet Tester ET310 : Industrial & Scientific

Review: Scans wires better than breakers. - Curious from the negative reviews, I thought as an electrical engineer, I would get it to work. Well, scanning the breaker board on second pass, it showed the wrong breaker. The microwave which is the only device on that circuit. The tester was plugged in another outlet. So I switched the breaker off, it still showed that breaker. Reset the scanner, learned the board all over, same wrong circuit. Or rather the middle of the breaker board. Then I read in the manual to unplug all devices from the circuit being tested. If I need to do that, this tester saves no time. Fortunately, some reviewers shared how they got it to work. Remove the breaker board cover and scan the wires. Bingo! Found the circuit the gas boiler is on. Without the need to unplug and reset the clocks in each room controller. 4 stars after all.

## Questions & Answers

**Q: Why don’t they have one for high voltages?**
A: What do you mean by high voltage? If you’re looking for something above 277/480, you’re going to want to spend more than $50. Otherwise you’re going to get
Yourself killed

**Q: Is the switch made so it won't turn on accidentally in a tool box?**
A: The pushbutton to turn on the unit is surrounded by a raised plastic lip.  The button sits flush with this lip.  If something in your toolbox pushes right up against the button hard enough it could possibly turn on.  You might consider getting a small zippered pouch such as the Klein Tools 69401 to protect the tester and help keep it from being accidentally turned on.

**Q: Can It uses on breaker off?**
A: No

**Q: Will it work if outlet has no power?**
A: No it will not work - it has to have a current to pick up the signal at the breaker box.

Ce détecteur de disjoncteur est un outil extrêmement pratique qui fait gagner un temps précieux lors de travaux électriques. Il permet de localiser rapidement et avec précision le disjoncteur correspondant à une prise électrique ou à un luminaire, sans avoir à couper les circuits un à un. Le système est composé de deux parties bien pensées : un émetteur qui se branche directement sur la prise ou le luminaire à identifier, et un récepteur qui sert à balayer le panneau électrique. Dès que le bon disjoncteur est trouvé, le récepteur émet des signaux visuels et sonores clairs, ce qui élimine toute confusion. Compatible avec les circuits de 90 à 120 V CA, l’émetteur intègre également un testeur de prise GFCI. Cela permet de vérifier l’état du câblage de la prise et de tester le bon fonctionnement des dispositifs GFCI, un vrai plus pour la sécurité. La prise à trois broches est parfaitement adaptée aux standards nord-américains. Autre point appréciable : l’émetteur se range directement dans le récepteur, ce qui rend l’ensemble compact et facile à transporter ou à ranger dans une boîte à outils. Un excellent outil, autant pour les bricoleurs que pour les professionnels, simple à utiliser, précis et très efficace. Un indispensable pour toute intervention sur un panneau électrique.
