Hi all. I’ve mounted a couple of things to studs before without an issue.
But I have a little bit more of an elaborate setup. I have a bunch of shelves for my cat that I want to put on the wall. I have a stud/wire detector, but one of the walls I wish to use has voltage detected across a very large area for some reason. And when I put my hand on the wall, it stops ever detecting any wires at all!!
Could there really be that much electrical wiring within this one wall??? There is a singular outlet in this area, but the detector goes off all over the wall, not just above the outlet.
My studs are very far apart at around 24 inches. So only small portions of the shelves will be drilled into the wall and the rest will be seated in the drywall with drywall anchors unfortunately.
How can I work on this project…drilling into both studs and drywall while avoiding the 10,000 wires that are evidently inside of my wall??? And also why do the “wires” all disappear when I touch the wall??
Thanks all lol.

I can confirm those detectors are not reliable. I had the same issue of active electrical detected everywhere in some of my walls. After destroying the wall, I can definitely confirm they were false positives. Some suggested this is more common in some types of constructions materials that tend to accumulate charges or something. Like you, touching the wall nearby helped with this. I support others’ advice to try painting a logical pictures of stud position (vertical, all the way up and down, and equally spaced) and plumbing/electrical position according to where switches, lights, taps.
