in the wall or ceiling, that the wires may pass behind a metal
object (like a furnace duct) that prevents the HOUND or
HOUND 2 from picking up the tracer signal, or the coaxes
may diverge from the path of the receiver. Before assuming
that the open has been located, try finding the signal nearby
or in an adjacent attached wall or ceiling. Also keep in mind
that it may not be possible to find the open in all situations,
because of the number variables involved.
Power Wires:
The FOX 2 cannot trace or identify “live” power wires. To
use a FOX 2 to trace a power wire, power must be removed
from the wire, and all loads must be removed from the wire.
This may be as simple as turning the circuit breaker off, and
turning off all of the loads.
NM-B (Non-Metallic wires, sometimes called “Romex”) can
be traced by putting one clip of the FOX 2 on the ground or
neutral, and the other clip on the hot wire. If the FOX 2 starts
beeping, remove it from the wires immediately. The wires
are live! Remove the power source. Trace the wires using a
HOUND or HOUND 2 in the usual manner. If the target wires
are in a metal conduit, they cannot be traced until they emerge
from the conduit.
To identify the wires, momentarily short the target wires to-
gether to active TrueTrace, and listen for the cadence change.
If it changes, you’ve found the target pair. If no change oc-
curs, keep searching. Warning, take care not to short to-
gether live wires! If this is a possibility, the user may wish
to use a light bulb to activate TrueTrace. Simply connect a
