Circuit Breaker Finder 90–120 V AC

The Amprobe BT-120 locates the correct breaker on energised 90 to 120 V AC circuits operating at 50 to 60 Hz. It is built for electricians and maintenance technicians who need to identify circuits without shutting down power.

Light and Sound Alerts

Visual and audible signals on the receiver confirm when the transmitter signal is detected at the panel. The dual alert method works in noisy environments or dim lighting where a single indicator could be missed.

CAT II 120 V Rating and 21 m Range

The tester carries a CAT II 120 V safety rating and meets CE, UL and N10140 standards. It traces conductors through walls, floors and metallic conduit at distances up to 21 m, so the receiver can stay at the outlet while the user scans the breaker panel.

Questions about this item

What battery does the receiver or transmitter need replaced over time?

The unit uses a standard 9 V battery in the transmitter and a 12 V battery in the receiver; replace either when the light or sound alert weakens.

How far can the receiver detect the transmitter through walls or conduit?

The receiver locates the transmitter up to 120 ft away through floors, metallic conduit or walls on energised circuits.

Does the finder get hot or make noise during continuous tracing?

It operates silently with only light and sound alerts, draws minimal current at 50 to 60 Hz and stays cool during all-day use.
