I have a new house where the drywall (sheetrock) guys covered one of
the outlets in my workshop. This outlet was part of a circuit of 5 or
6 other outlets. We did not notice this until too late, therefore this
circuit was never completed. How can we locate the "missing" box so
that we can join the wires in that box and complete the circuit?
thanks,

Hello Waring,

   First, I would make the sheet rock guys come find the outlet! 

   Second, do the prints show the location of the outlet?

   Third,  if you have a tone generator and speaker probe (or
amplifire), check Page 8 for directions better than I can describe.
I'd like to add though, that you need to turn off all power to the
house. If you know which circuit breaker the circuit is on, unplug the
breaker switch, and attach the tone generator to these wires,
following the directions. If the wires to this circuit are not
attached at all, they should be in the breaker box, loose. Also,
unplug anything that is unplugged into the other outlets on that
circuit.:

  If you don't have the equipment, you may be able to borrow it from
any cable splicer or independent phone contractor or electrician.
Sometimes you can pick up these tools in a pawn shop. If not, they can
be found at large home improvement stores.

I hope this helps you! Please ask for a clarification and allow me to
respond, if not!

Good Luck, Crabcakes

locating outlet + tone generator

All you need to do is measure the other outlets in the room from the
floor up, they should all be the same. except maybe the switchs are
differant. Than take a flat edge or level and run it over the area you
think it might be.It will have a hump in it from where the sheet rock
did not go flush against  the wall. measure up and add 2 inches for
center of box and cut out with a keyhole saw. thats it and good luck
