When I last worked on a standard construction crew, many years ago,
the boss had some kind of hand-held electronic device, which could
sense the presence of electrical wires behind wallboard. He could
trace a piece of romex wire run through the studs, and find where it
turned from running horizontally to vertically, for example. The
wires are supposed to be a couple of inches behind the face of the
wallboard, so that should be similar to the plaster thickness in a
plastered bale. If I remember correctly, it required the wires to
be live, in the sense of having power available through the wire. It
didn't require any load on the circuit.
I would think by now these devices would be more sophisticated and
cheaper. If you are using metal boxes for the electrical outlet
boxes, then a simple metal detector should work well. I use the
Wizard brand metal detector for finding staples and nails in rough
lumber, before running it through my planer. It cost about $80, from
Woodworker's Supply (1-800-645-9292). It looks similar to the
hand-held metal detectors used by airport security. It can detect a
fine wire staple at the depth of an inch in hardwood, so I think it
could easily find a metal electrical outlet box. But I bet the
electrical supply houses have something similar, designed for your
PS. I just checked the Woodworker's Supply web site
<<a target="_blank" href="http://woodworker.com">http://woodworker.com</a>>. The equivalent to the detector that I have
is the Lumber Wizard ?III Model 25506 Metal Detector For Woodworkers,
catalog number 109-097, $76.99. The specific web page with this and
other metal detectors is

So here is a more practical question. Anyone have an efficient way
of finding buried electrical outlets (post-plaster)? I know this
seems basic, but we lose one every other project or so. Thought I
would lighten things up! Any tricks to share?
