Safety Information
To avoid possible electric shock or personal injury, follow these guidelines:
• Do not use the transmitter/receiver if it is damaged.
Before you use the transmitter/receiver, inspect the
case. Look for cracks or missing plastic. Pay particular
attention to the insulation surrounding the connectors.
• If this product is used in a manner not specified by the
manufacturer, the protection provided by the equipment
may be impaired.
• Do not use the transmitter/receiver if it operates
abnormally. Protection may be impaired. When in doubt,
have the transmitter/receiver serviced.
• Do not attempt to repair this transmitter/receiver. There
are no user serviceable parts.
• Use caution when working above 30 V ac rms, 42 V peak,
or 60 V dc. Such voltages pose a shock hazard.
• Do not operate the transmitter/receiver with the battery
door removed or loosened.
• CAT III equipment is designed to protect against
transients in equipment in fixed-equipment installations,
such as distribution panels, feeders and short branch
circuits, and lighting systems in large buildings.

Introduction
The ECB50A Circuit Breaker Finder and AC Cable Locator
consists of a transmitter and a receiver. Similar to radio signals,
the transmitter functions by means of a coded carrier sending
a signal into the cable. Using the built-in sensor, the receiver
can indicate the transmitted code as a symbol on the display
as well as providing an audible signal. The audible sound level
automatically intensifies as the source is approached.
The ECB50A is the ideal tracing instrument for sorting out
AC wires in a bundle of cables, tracing lines in overhead
installations and walls, and assigning current circuits to fuses.
Using the ECB50A you can:
• Sort out a single wire in a bundle of cables.
• Trace and find AC cable in walls.
• Assign current circuits to fuses within fuse panels.
• Switch between locating cable lines or locating fuses.
• Adjust sensitivity when tracing lines and locating cables.
Finding Circuit Breakers and Fuses See Figure -1-
1. Turn on the ECB50A receiver using the On/Off switch.
2. Set the Fuse/Line switch to the Fuse position.
3. Plug the ECB50A transmitter into the voltage socket
connected to the fuse or circuit breaker.
4. Turn the On/Off switch toward the top of the receiver to
set sensitivity to the highest sensitivity level. Turn toward
the bottom of the receiver to reduce sensitivity.
5. Position the receiver at a 90 degree angle (perpendicular)
over the top of the fuse or circuit breaker. Adjust the
sensitivity level until the “H” code is displayed along with
a blinking LED and an audible tone.
6. If a reception signal is received at several fuses/circuit
breakers, use the On/Off switch to reduce the sensitivity
until the minimum reception is received. Repeat this
procedure until only one fuse indicates a reception signal.
This fuse/circuit breaker protects the socket to which
the transmitter has been connected. The tracing depth
amounts to approximately 10 cm (4 in).
Caution
Keep hands clear of wiring when tracing wires or fuses in
distribution panels.

Locating and Tracing Cables in Walls See Figure -2-
1. Turn on the receiver using the On/Off switch.
2. Set the Fuse/Line switch to the Line position.
3. Plug the ECB transmitter into the socket for AC line to be
traced.
4. Turn the On/Off switch toward the top of the receiver to
set sensitivity to the highest sensitivity level. Turn toward
the bottom of the receiver to reduce sensitivity.
5. Place the ECB50A receiver close to the transmitter to
receive a confirmation signal that both ECB50A test
components are active and working. The receiver is
receiving a signal from the transmitter when it displays
the letter “H” on the display and the LED is blinking.
Also an audible signal is present with varied loudness
depending on strength of signal received.
6. Next, begin locating the signal in the cable to be traced
by circling around the socket. When you receive a
signal, reduce the sensitivity until the minimum signal
is received. If the signal decreases, the receiver is either
moving off the AC cable path or the cable is installed
deeper into the wall. If necessary, adjust the sensitivity
level to increase the signal strength. Depending on local
conditions, the tracing depth amounts to approx. 0 to 40
cm (0 to 15 inches).
Sorting Out a Single Wire in a Bundle of Cables
See Figure -3-
1. Turn on the receiver using the On/Off switch.
2. Set the Fuse/Line switch to the Line position.
3. Plug the ECB transmitter into the socket of the AC wire to
be traced.
4. Turn the On/Off switch toward the top of the receiver to
set sensitivity to the highest sensitivity level. Turn toward
the bottom of the receiver to reduce sensitivity.
5. Place the ECB50A receiver close to the transmitter to
receive a confirmation signal that both ECB50A test
components are active and working. The receiver is
receiving a signal from the transmitter when it displays
the letter “H” on the display and the LED is blinking.
Also an audible signal is present with varied loudness
depending on strength of signal received.

6. Next, try to locate the transmitted signal at the bundle of
cables. When you receive a signal, reduce the sensitivity
until the minimum reception of the signal is heard and
seen. If necessary, increase the sensitivity somewhat to
confirm the signal.
Product Maintenance
As long as the instructions in this manual are followed, no
special maintenance is required.
Cleaning
Disconnect the instrument from all circuits. To clean the
transmitter/receiver, use a soft cloth moistened with water. To
avoid damage to the plastic components do not use benzene,
alcohol, acetone, ether, paint thinner, lacquer thinner, ketone
or other solvents to clean the transmitter/receiver. Allow a
recovery time of 6 hours after cleaning before operating the
instrument.
Replacing the Battery See Figure -4-
A red LED indicates that the battery needs to be replaced. To
replace the battery:
1. Turn off the instrument using the On/Off switch
2. Loosen the screw on the back of the instrument and open
the case.
3. Remove the battery and insert the new 9 V alkaline
battery using the correct polarity. Recycle your discharged
battery.
4. Reassemble the case.
5. Insert the screw and tighten it.
