4.1 RCD-Protected Circuit Wire Tracing
Method 1
• Whenever possible use separate neutral connection. For this connect green test lead to a
separate neutral wire at the RCD or at a connection point as close to the RCD as it is possible.*
• Perform tracing as described in the Wire Tracing (SMART and TIP SENROR modes) or
Breaker/Fuse applications.
*Note: Please make sure that line/phase wire and separate neutral are connected to the
same RCD, otherwise the RCD will trip.

Method 2 – If separate neutral connection is not practical:
• De-energize the circuit.
• Connect a transmitter directivity to the wire as described in Wire Tracing method for
de-energized wires using separate ground connection (green test lead connected to the
separate ground instead of neutral wire).
• Perform tracing as described in the Wire Tracing or Breaker/Fuse applications.
