We currently have a Romex cable that was used to feed loudspeakers in
a remote building. The cable is buried probably not more than a foot
underground. We have access to both ends but have need to trace the
path of the cable underground. We can if necessary connect one end to
120V and the other to a high resistance load like a space heater.
What equipment will we need to trace the path of the cable? Is
this easier (and less expensive) to do if the cable is energized? And
if we choose not to purchase the equipment, where would we look for
rentals or for someone to come out to perform the service?
Help much appreciated!
If the return current flows thru an adjacent wire, the
external fields cancel.
There are companies that hunt for hidden stuff before roadwork
is done. Call the city engineering department and see if they
know or can refer you to one of the finder companies.
Fone company probably has the stuff too.
You can get field detectors at Home Depot used to find wires in walls.
I tried three different ones. A Fluke LVD1 had about twice the range of the
others. Nearly a foot in air. Ground may make a big difference.
I'm too lazy to dig a hole.
Metal detectors, especially older ones, work by putting a signal
into a sense coil and looking for frequency changes caused by the metal.
If you put a signal of nearly the same frequency into the underground
wire, you may be able to hear the beat frequency in the metal detector.
That's the simplest thing I can think to try using equipment you can
likely borrow for free from your friends.
Gack! I agree with Mr. Morgan. A line voltage detector won't work through a
foot of dirt, AFAIK. Energizing a wire previously used as a low-voltage
speaker wire with 110VAC is not the preferred method in any case. The wire
could be compromised, hooked up to controls in an unknown area or even part
of some previous, ill-conceived "shock a burglar" system. Best to use low
voltage tools like the Fox/Hound set or something similar.
Even that advice comes with a caveat. We don't know what the OP wants to do
with this wire. If it's to carry significant current, like a space heater,
I'd be tempted to pull up what exists and re-lay cable of known good quality
installed as per the NEC and/or the local rules governing outside wiring,
and that usually means putting a GFCI in the loop somewhere, at least.
The OP has no idea if the wiring was being used for speakers because it's
unsuitable to carry line voltage because of damage or some other problem.
No way to tell if it's spliced every 20' with nothing but black tape or wire
nuts or has long gashes in it from being pulled against some sharp edge.
I wouldn't, in any case, energize it with line voltage in the hopes of being
detectable by some means other than a standard wire tracing kit with a tone
generator and a matching receiver/tracer.
I know, I know but... Ask around for someone who dowses. If he'll do
it for free you can then dig a test hole to confirm the findings.
I had never tried to find a buried wire before so just went out and
tried the only one I have around here. It worked. I don't trust the
rods without digging to confirm though. In this case I got a firm
indication on a wire buried a couple feet with no active current (feed
to shed with nothing turned on).
BUT I knew within a couple feet where the wire was. Same as all my
other "finds", I either already know the location of something or
there are clues that say the logical place for it to be...except one
and I would sure like to dig in my neighbor's lawn to see if the pipe
is there. :).

Fergeddabout it. It's so easy, I just went out in the yard and did one.
So, where do I collect my million dollars? You have said before that this
could not be done, and that they were offering a million dollars. Well, I
just proved that I can do it, and I believe that the offer is bogus, or I
would have been paid by now. Thousands of people have proved they can do
this, yet that bogus site hasn't payed anyone yet, renegging for one reason
or the other. By the way, the earth is flat, and man didn't go to the moon,
but to a remote valley near Tooele, Utah.

So, Bud, I know you don't believe in this. So, PUHLEEEEZE don't bore us
with any more statements that it can't be done. Just because your small
brain can't wrap around it doesn't mean it isn't so.
Another good youtube video:
I didn't say it couldn't be done. I said it hadn't been done.
The offer is very real.
Many have tried, none have succeeded.
Apply and get your $1 million.

The nature of the test is agreed to by both sides. There is no
"reneging". The dowsers failed to pass a test they agreed was fair.
There have been a number of other tests, detailed in wikipedia dowsing.
They have failed.
Sort of related, alleged psychic Sylvia Brown said on Larry King she
would "take the million dollar challenge". Strangely it has never
happened. One excuse was she couldn't figure out how to contact Randi.

expensive piece of gear OR ask a dowser to do it for freebie and he
only has to dig a one foot hole to confirm. Geeze but that is one
hard decision to make.
