The Current index helps to confirm the line's identity.

If an adjacent line is running parallel with the object line.

If two lines are crossing:

Locating T connection

Splicing/jointing points of Power cable, Telephone cable, Gas pipe, Water pipe, or Sewer pipe.

Line-A with a 2.6 mA current
index is the object line.
Even though signal is smaller.

The line with the highest current index is the object line into which the signal is being broadcast.

Line A with a 2.0 mA current index is the trace object.
