Introduction

The ECB50 Circuit Breaker Finder and AC Cable Locator consists of a
transmitter and a receiver housed in a protective denier case. 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 ECB50 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 ECB50 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

1. Turn on the ECB50 receiver using the On/Off switch.
2. Set the Fuse/Line switch to the Fuse position.
3. Plug the ECB50 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 of 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, 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 protects the socket to which the
transmitter has been connected. The tracing depth amounts to
approximately 10 cm (4 in).
