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.
