Southwire Tools 40116N 100-600V AC NCV Detector

After years of using multimeters to determine if a circuit is live, I finally decide to buy a non-contact voltage tester. Boy, am I happy that I did. The dangerous part of working on 110 V circuits is to try to get to the black (line voltage, hot wires) behind a light switch or plug, along with neutral (white). In my case, the yahoos who owned the house in the past did something beyond goofy, going into stupid territory. They spray painted the wires all white when they painted the walls. Now, imagine trying to probe the wires and not being sure what's what because they are all the same color! Even if it's different colors, there's always the risk of an electrical shock when you remove the wire nuts securing the connections. You're also holding the probes, plus the multimeter itself. If something slips, your instinct is to catch it, which means you might brush against a live wire. Having a NCVD makes life a lot easier. As always, test on a live circuit prior to each and every use, to make sure the tester still works.

Lo compré para el trabajo de mi esposo y me dice que lo lleva a todos lados. Él es ingeniero de Servicio y le da un buen uso, siempre lo carga y dice que es de los mejores.

Economical safety tool. Works good and easy to use. Device has to be quite close to live circuits to consistently detect them. Solid build.

Excelente sensibilidad para detectar voltaje y muy facil de usar, en adición la lampara que posee es de gran utilidad. excelente producto, presenta un apariencia muy ruda y ya teniendola en las manos, efectivamente esta muy bien construida.

Seems to do the job..no issues..changed a two and a 3 pole smart switch. Definitely helped to have it..!!!
