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)
