Tracing lines in conduits

Note

☞

Note that the magnetic field on the line to be tested can also influence neighbouring
conduits. That is why the receiver should be held at least 2 m away from the next
switch box.
Conduits of steel having thick walls attenuate the signal to be traced while conduits
of plastics or aluminium do not impair the signal.

➭

Connection

:

Connect one socket of the signal generator to a separate earth, the other
one to a live line.

➭

Locating

:

When searching for a line, proceed as described under "General proce-
dures for live lines" on page 9.
