## Description

## Key features

The INSTRODOTS CBF01 is a two-part digital circuit breaker finder that speeds up locating breakers on standard 90-135V AC panels while reducing guesswork and trips to the breaker box. It combines a transmitter that doubles as a GFCI outlet tester and a handheld receiver with visual and audible alerts, so you spend less time testing and more time fixing. If you need reliable breaker identification for home, office, or light industrial work, this tool helps you confirm circuits quickly and safely.

## Specifications

## What stands out

The transmitter uses signal-injection technology and a clear color LCD to show wiring conditions and GFCI test results, while the receiver presents an analog bar display and buzzer alarm for fast pinpointing. The unit identifies six common wiring faults and can test GFCI trip time according to manufacturer notes, which adds a layer of safety when verifying outlets. The auto-hold feature locks readings for hard-to-reach receptacles and the tester alerts you to low battery and powers off automatically to conserve energy.

## How to use it

Start by plugging the transmitter into the outlet you want to trace, then scan the breaker panel with the receiver until the bar display peaks and the buzzer sounds. It’s a straightforward workflow that removes the need for sensitivity dials and reduces false positives. It’s a great fit if you value speed over fiddly setup, and worth considering if you perform routine electrical troubleshooting or panel labeling.

## Care & maintenance

Wipe the housings with a dry cloth and store both pieces in the included carrying case when not in use to protect the double injection precision case from dust and drops. Replace the 2 AAA batteries for the transmitter and the 9V battery for the receiver as soon as low-battery indicators appear to maintain accurate readings.

## What you get

The kit includes the transmitter with GFCI outlet tester, receiver, 2 AAA batteries for the transmitter, 1 9V battery for the receiver, a storage bag, and a user manual. Lifetime customer support is offered by the manufacturer for added confidence.
