4.10 Mapping a Circuit using Test Leads Connection

Mapping a circuit can be only performed on a De-energized circuit when using test leads connection.
1. Switch the breaker/fuse to the OFF position.
2. Set up the Transmitter and Receiver as described in the De-energized Wire Tracing as
described in section 3.2.
3. Scan face plates of receptacles and wires towards load with the Tip Sensor of the Receiver
4. All the wires, receptacles and loads that have a strong signal as indicated by the
Receiver are connected to this breaker/fuse.

4.11 Tracing Breakers/Fuses on Systems with Light Dimmers
Light dimmers can produce a significant amount of electrical "noise" that consists of multi-
frequency signals. In some rare situations, the Receiver can misread this noise, often called
a "ghost" signal, as a Transmitter - generated signal. Therefore, the Receiver may provide
misleading readings. When locating breakers or fuses on systems with light dimmers, the
dimmer should be off (the light switch is off). This prevents the Receiver from indicating a
wrong breaker/fuse.
