When to use a plug connector
The plug connector is used when it is necessary to put a signal onto a line to trace it from the domestic plug to
the service cable and there is access to a live domestic socket. The plug connector applies an 8kHz/33kHz
transmitter signal to a live domestic power socket and, via the domestic wiring system, onto the service cable
and the supply cable in the street.
How to use a plug connector
•
Insert the plug connector to the transmitter accessory socket and fit the plug to a live domestic power
socket. The socket must be live for signal application.
•
Switch on the socket.
The signal is applied between the live and ground conductors on a three-pin plug. The connector can also be
fitted with a two-pin plug with the signal applied across the live and neutral.
The user and the transmitter are fully protected from supply voltages up to 300V, DC to 65Hz.
Live cable connector
Safety precautions
WARNING. THE LIVE CABLE CONNECTOR IS TO BE USED ONLY BY OPERATORS LICENSED OR
PERMITTED TO WORK ON LIVE CABLES.
Authorisation
The live cable connector applies the transmitter signal to a live cable. It must only be used by personnel
licensed or permitted to work on live cables and who are trained in the safety precautions related to working on
live cables.
When to use a live cable connector
The live cable connector applies an 8kHz/33kHz tracing signal safely to live low voltage cables. The live cable
connector is used to trace and identify cables and locate simple cable faults by connecting directly to a live
conductor at a domestic cut out, street lamp, junction box, or substation low voltage busbar.
Introduction to the live cable connector
The live cable connector consists of a box with a transmitter connection cable at one end and two output cables
at the other end. One cable terminates in a red connector and the other cable terminates in a black connector.
The two output connectors each incorporate a 1-amp fuse, which can be accessed by screwing the connector
head from the connector body.
How to use a live cable connector
Plug the transmitter connection cable into the accessories connector on the transmitter. Connect the red
connector to the live conductor and connect the black connector to neutral or ground as appropriate. The
transmitter indicates by change in tone or on the display when a satisfactory connection has been made.
The user and transmitter are fully protected from supply voltages up to 500V, DC to 65Hz.
Positive cable tracing and identification in a domestic house:
•
Connect the red clip to a terminal box connection. Remove fuse if necessary
•
Connect the black clip to an independent ground point outside.
