QUESTION: I would like to find out if there is any electric wires behind my drywall and where they are as I want to install shelves on my garage wall and I do not trust that there are the metal plates over the studs if there were wires there.I do not want to chance putting a screw into a wire
I have never seen a voltage detector that would reliably locate energized cables in a wall. Most only work with close access to the cable, which suggests it is exposed, in which case you don't need the tester....
I have often traced cables with a circuit tracer, but I don't know how well the $69.95 models will work for you. I have a professional grade device which cost much more and still requires imagination and practice to use effectively.
Since it is the garage wall, it may be relatively easy to figure out where there may be wires, however.
I invite you to send photos of the area where you want to install the shelving and the reverse side of the wall if it is an interior wall backing up to an interior room.
Send them to email@example.com
Also, give me an idea of what is above these areas and where your service enters, garage or basement.
