17. 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 4000CON in the high sensitivity range Refer to Figure 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 sensitivity range of the R 4000CON So if tracing the branch wiring through the walls is not necessary use the C2901 for quicker connection Refer to Figure 12 Easy tracing of wires and buried cable is accomplished by simply separating wire from the return path ground Instead of using the neutral wire or the conduit as the ground use the C2902 Alligator Clip cord set and attach the grounding test lead to a separate ground such as a water pipe Refer to Figure 13 Using the A2202 Clamp On Transmitter Accessory The A2202 will allow non contact signal indication onto energized or non energized conductors On energized lines the signal will propagate downstream to the end of the circuit provided there is a current flowing in the circuit Unenergized lines must be grounded at both ends or made into a complete circuit The signal strength can be 11 boosted significantly by using the B20
