Cable locators for tracing wiring and cables

A cable locator traces lines and cables that run out of sight in walls, floors and distribution boards. For electricians and installers, it is the fastest way to identify a specific wire, link a fuse to the right circuit or pinpoint a break in a line. A set usually consists of a transmitter that puts a signal on the cable and a receiver that lets you follow its route and determine the end point.

This way you work in a targeted manner and avoid opening up walls unnecessarily. When choosing, consider the application: for de-energised installations a basic set is enough, while tracing live cables or working in industrial settings calls for a more rugged, sensitive version. A clear signal indication and good interference suppression make the difference at busy, densely wired distribution boards.

Brands such as Fluke and Beha-Amprobe supply devices for light service jobs and for intensive professional use. Choose a set that matches the installations you work on most often.
