Question: Can it check if romex wire is hot without cutting the romex protective cover? Need to find a hot circuit in attic for ceiling fan installation
Document: Works well and as advertised. Tells when a wire is still hot and when it's not. Just what you need from a voltage tester and what you would expect from a company like Klein.
This little electrical tester is literally a life saver. Don't even think about doing minor electrical work around the house without it. While renovating our cabin I used it recently to double check that lines were off after flipping the breakers and I found a number of wires that were still hot!
We have some really old wiring, it is cloth insulated so no color code, could not tell which wire was hot in the ceiling boxes but this little fellow did the trick every time. Now our hot wires are all marked so the next who open the boxes will not have a mystery. Low cost item that belongs in every tool box.
I used a non-contact current tester in my daughter's old house when replacing the outlets for her so I could be certain which wire is "hot" and which is not. I thought it was nice, but unnecessary if I got along without one all of these years. Then I needed to troubleshoot a string of Christmas tree mini-lights.
I saw this item in a short review in a recreational vehicle magazine just a few days before my husband unwittingly proposed a use for it. Our worksop is a converted 2-car garage. He wondered whether the wiring left behind after removal of 2 single-bulb fixtures might still be live and available for installation of small spot lights. I ordered this tester as a way of checking for voltage without removing wire nuts or digging around in the old junction boxes.
Best $$ I have spent in a while. Much easier to test for power in outlets, switches or any circuit. Dont know how I lived without it.
It's okay only because I get a few false positives still and I have to check circuits twice to make sure they're really dead or alive. Sometimes it will say a dead line has juice and sometimes it will say a live circuit is dead. Check twice and cut once.
Now unlike other testers this tester also loud audible bleeps to show if the circuit is still hot (live) or has no power. Let me tell you, that is very handy not only from a safety aspect, but as a general benefit as well.This product is also very durable as well.
very easy to use and batteries last forever in this unit. makes it very easy to check if you have power to the source without making that guess that results in a shock.
This tool is invaluable if you are fooling with live connections. It tells you immediately if you have turned off the power to the location you are working on & if are about to touch a hot wire. I have used it time and time again.
Answer: yes
