Can they be used to trace cat 5 cables behind drywalls?
Can they be used to trace cat 5 cables behind drywalls?
Terran said:I didn't see any replies either, so I just checked it. My conclusion
is that if the cable is touching the drywall on the other side from
you, you'll hear it fine. If, however, it's the full 3.5" away that
it might be (assuming a 2x4 behind the drywall), tracing it will be a
much more questionable proposition.

Cat5 cabling is so tightly twisted that if you connect the toner to a
single pair, you'll get nothing when the probe is right next to it. So
you have to connect one wire of the toner to one pair or one wire of one
pair, and the other wire of the toner to another pair or wire of another
pair. Try it and you'll see what I mean.
I have one probe that has a volume control and can be turned up, so it
will make enough noise to detect fairly far away - some probes don't
have a volume control. But it depends on what's around the cabling, how
new the battery in the toner is, etc. The toner will operate on a
battery that's down to just a few volts, so check it occasionally with a
DMM and replace it when it's below 7.5V.
This is true not the same pair. I have the older version of Fox and
Hound by Triplett (got it at a garage sale for a couple bucks):

The leads to be traced can't be grounded or connected. I have been
able to trace Cat-5 cables by just waving the probe within a couple of
feet of cables on the surface. I also found the position of 2 cables
that I fished into a lathe and plaster wall from another floor (not in
conduit). Drilled a 1/4 inch hole and fished them out with a hooked
wire. Nice and neat.

Was it a wood lathe or a metal lathe?Mike said:You must have thick plastering for the lathe not to show up poking out
of the wall!

Robert said:Made out of wood; that is wht it was so hard to find..

Richard said:Jeez I didn't know this was a spelling test. Well I actually do have a
metal lathe. It's only 8 " between centers and it would fit into a
lath and plaster wall. Sorry for the misspelling my spell checker
doesn't check context. It does seem to be a common missuse:

More on the subject l just used my kids metal detector to trace a live
bx in a ceiling to determine that it just ended in the middle of
nowhere (bare wires with old tape). So I was able to eliminate it and
terminate the the wiring in the box.
