I was supervising the buildout of a four-unit apartment building when the electrical contractor went ballistic, because the drywall crew had covered an electrical box without providing a cutout for it. The electrician was ready to start bashing holes randomly to find the box. If he did, the drywall crew would have had to come back to fix the destroyed wall.
The electrician had to do his job, and he didn’t want to waste his time because of someone else's mistake. I pleaded with him: “Please don't destroy the wall. Let me see if I can find the electrical box.”
There was no access to the backside of the drywall, so I took a variable-speed drill and put some rubber bands on the trigger, so it would growl away slowly. I ran a jumper wire from the drill cord to the end of the buried wire at the breaker box. Then, with a transistor radio tuned off channel, I could hear the RF noise generated by the sparks on the motor brushes as I brought the radio into proximity of the wire. In a couple of minutes, I found the box and cut neatly into it.
