or ceiling, that the wires may pass behind a metal object
(like a furnace duct) that prevents the HOUND 3 from pick-
ing 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 at-
tached 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.
8.1.9.4: 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 3 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 True Trace, 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
