The signal generated by the T-4000 is present at all points around the circuit.
The T-4000 connected to a 110V outlet via the C2901 cord set will cause an incoming
signal on the neutral wire as well as an outgoing signal on the hot wire. The close
proximity of these two wires may cause the signals to cancel each other, making it
difficult to trace the cable in these areas. In this case, keep the R-4000 in the high
sensitivity range. (Refer to Figure 11)
Fig.11
At the panel breakers, the hot wire is separated from the neutral wire (where it is
grounded) allowing easy circuit breaker identification. In that case, use the Low sensi-
tivity range of the R-4000. So, if tracing the branch wiring through the walls is not nec-
essary, use the C2901 for quicker connection. (Refer to Figure 12)
