Identifying Breakers And Fuses (Energized And De-Energized) - Amprobe AT-6000 User Manual

3. MAIN APPLICATIONS - TRACING ENERGIZED AND DE-ENERGIZED WIRES

3.2 Identifying Breakers and Fuses (Energized and De-energized)

Breaker mode automatically adjusts the sensitivity of the Receiver. As a result, the Receiver
will pinpoint and indicate just one correct breaker. This enhancement helps to remove signal
strength analysis from the breaker identification process that is typical for less advanced
wire tracers.
Note: For breaker locating, a simplified direct connection to hot and neutral wires can be
used because these wires are separated at the breaker panel. There is no risk of signal
cancellation effect if wires are at least a few inches away from each other. However, the
separate ground connection (see pg. 11) should be used for superior results specifically if
wires need to be traced in addition to breaker identification.
The simplified direct connection to hot and neutral wire will NOT trip the GFCI circuit.

Connecting the test leads
1. Connect the Transmitter using either simplified direct connection or separate ground
connection.
2. If the simplified direct connection method is used, connect the test leads directly to
the hot and neutral wires. While locating a breaker, wires will not be traceable as the
signals will cancel each other out.
3. For separate ground connection, first connect the red lead to the Energized hot wire
on the load side of the system. The signal will ONLY be transmitted between the outlet
to which the Transmitter is connected and the source of power.
4. Connect the green lead to a separate ground, such as a metal building structure, metal
water pipe, or ground wire on a separate circuit.
Setting up the AT-6000-T Transmitter
1. Press the ON/OFF key to turn on the Transmitter.
2. Verify that the test leads are properly connected. The red LED voltage status light will
illuminate for Energized circuits with a voltage above 30 V AC/DC. If the voltage is
De-energized, the light will be off.
3. Select the HIGH signal mode for Breaker Locating.
