Why does a machine knock out after mounting profiles for drywall?
It knocks out an outlet machine, I think it was punched with a self-tapping screw. When the indicator screwdriver touches the profile, the frame lights up. Does this mean pierced or not necessary?
You yourself answer your question. The line is faulty after installing some profiles (I believe that you are installing drywall). So the point is this. As for the screwdriver - not necessary. It depends on which screwdriver. Those with a LED and batteries light up on a wire stub lying on a table, while those with a neon bulb and without batteries almost always only have voltage (I personally have not encountered an error or a malfunction).
