Locating and Avoiding Street Lighting Cables

What This Video Covers

Built as a toolbox talk after real street lighting strikes, this film takes one job from start to finish: getting a Genny signal onto a lighting column and tracing the cable with the CAT. It opens with the connection being made at a real column, shows a simple trick for improving the earth on paving, explains why that one connection can hand you the whole street, then walks the method on a live site. It closes on the fault that catches CAT4 users out: a signal so strong the needle is all or nothing.

Connecting at the Column

The film starts where the survey should: at the lighting column, hooking the Genny lead on and getting the earth in close. Where the ground is paved and an earth pin has nowhere to go, a bottle of water on the pin's contact point does the job, and the video shows exactly that.

The whiteboard section then explains the part most training skips: where to put the earth relative to the column and the cable, and why it matters more than how close to the column you work.

The Method on Site

The middle of the film is real fieldwork: direct, capacitance and clamp connections, following the signal along the street, and monitoring it as you go, because a sudden change usually means something has joined or left the line.

Too Much Signal, and How to Fix It

If the signal strength meter is all or nothing with tiny movements of the sensitivity control, the signal on the utility is too strong. The final section shows the fault on screen and the fix: reduce the strength by pulling the earth pin out, then watch how much easier the meter is to control.
