Instrodots Circuit Breaker Finder Tool with GFCI Tester – 90-135V AC, Includes Carrying Case

Overview

The Instrodots CBF01 Circuit Breaker Finder is designed to help you map electrical circuits quickly and confidently. It supports standard 90-135V AC systems, making it a versatile companion for residential, commercial, or light industrial work. The kit blends practical diagnostics with thoughtful design, delivering a tactile, reliable experience that can reduce guesswork during troubleshooting and panel work.

Two-Part Identification System

Identify the exact breaker in three simple steps with a transmitter inserted into a live outlet or fixture and a receiver that scans the panel. No fuss with sensitivity dials—just a straightforward workflow that helps you pin down the right circuit efficiently.

• Transmitter injects a circuit signal for detection
• Receiver analyzes the panel and displays clear readouts
• Three-step process for fast, reliable mapping

Visual & Audible Feedback

The transmitter features a large VA reverse color display and bright LEDs that indicate status at a glance. The receiver offers an analog bar display plus an audible alert, helping you confirm the correct breaker even in dim spaces.

Built-In GFCI Tester

In addition to locating breakers, the transmitter can test GFCI outlets and check how quickly they trip, helping you assess wiring conditions. An auto-hold function makes data capture easier for hard-to-reach outlets.

Flexible Accessories Kit

Three essential adapters extend the tool’s versatility: a 3-prong to 2-prong grounding adapter, a light socket adapter for fixtures, and an alligator clip adapter for bare wires. These extras help you map circuits from outlets to fixtures and beyond.

Durable, User-Friendly Design

Both transmitter and receiver feature automatic power-off and low-battery indicators to simplify field use. The double injection precision case provides anti-dust, anti-skip, and anti-drop protection, while the included carrying case keeps components organized and portable for on-site testing.
