INTRODUCTION

Thank you for purchasing General Tools & Instruments’

(General’s) BF10 AC Circuit Breaker Finder. Please read this

manual carefully and thoroughly before using the product.

The BF10 can perform two functions:

1. Automatically identify the circuit breaker or fuse

associated with any 110V outlet without tripping the

breaker or blowing the fuse

2. Identify five common receptacle wiring faults

The AC Circuit Breaker Finder has two components—an AC-

powered transmitter and a battery-powered receiver. When

the transmitter is plugged into an AC outlet, it powers on and

sends a signal down the branch circuit all the way to the

circuit breaker panel. If the tip of the battery-powered

receiver is then used to “scan” all of the panel’s breakers (in

other words, touch each one in turn), a sensor in the tip will

light a green LED on the front of the receiver each time it

detects a signal. If no signal is detected, a red LED will light.

A first scan will cause the green LED to light several times if

the transmitter’s signal has leaked onto adjacent branch

circuits. On a rare occasion a second scan may be needed.

During each scan, the BF10 uses a patented circuit that

automatically adjusts the sensitivity of the sensor to rule out

weaker signals representing “false positives.”
