Locating Street Lighting Cables

Chapter 24 of 33 · printed page 14

To locate street light cables, the Genny should be connected as follows:

  • Switch the Genny on and insert the connection leads.
  • Connect the black lead to a suitable earth as close to the column as possible.
  • Connect the red lead to the metalwork of the column.
  • Adjust the signal level control so that the CAT display is set to half scale.
  • Where possible, walk around the column making a note of any signal(s) detected.

Once a signal has been detected and the direction has been established, the route can be followed.

Cables to and from other street furniture may also be detected by making a direct connection to the metal structure.
