3.2 Identifying Breakers and Fuses (Energized and De-energized)
Note: For breaker/fuse locating, a simplified direct connection to line/phase and neutral wires
at the outlet can be used because these wires are separated at the breaker/fuse panel. There is
no risk of signal cancellation effect if wires are at least a few centimeters away from each other.
However, the separate neutral/ground connection (section 3.1) should be used for superior
results specifically if wires need to be traced in addition to breaker/fuse identification.
The simplified direct connection to line/phase and neutral wire will NOT trip the RCD circuit.
Figure 3.2a: Simplified direct connection
Connecting the test leads
1. Connect the Transmitter using either simplified direct connection or separate neutral/
ground connection.
2. If the simplified direct connection method is used, connect the test leads directly to the line/
phase and neutral wires. While locating a breaker or fuse the wires will not be traceable as
the signals will cancel each other out.
3. For separate neutral connection, connect the red lead to the line/phase wire on the load side of
the system. The wire can be Energized or De-energized. Connect the green lead to a separate
neutral, such as a neutral wire as close to the breakers/fuse as it is possible.
TIP: The Transmitter, with the red test lead, can be directly connected to the live wire of the
working electrical equipment under load (motor, electronics, etc). Tracing can be performed
without needing to turn off the equipment or switching power off.
