Klein Tools 80101 Circuit Breaker Finder Kit — GFCI Receptacle Tester, NCVT, and MM320 Multimeter

All-in-one electrical tester kit for homeowners

The Klein Tools 80101 kit brings together four essential testers in a compact, durable package designed for in-home electrical work. From the tactile grip of the handheld tools to the bright backlit LCD readouts, every element is built to support quick, confident testing whether you’re wiring a new outlet, diagnosing a tripped circuit, or simply checking outlet conditions.

What’s inside and how it helps

• Digital Multimeter MM320 measures voltage up to 600V AC/DC, current up to 10A, and resistance up to 2 MΩ; it also tests batteries, diodes, and continuity for quick circuit checks.
• NCVT3P Dual-range Non-Contact Voltage Tester detects 12–1000 VAC (and 70–1000 VAC for certain low-energy applications) with a broad sensitivity range, plus a flashlight for dim spaces.
• GFCI Receptacle Tester RT250 features a large backlit LCD and clear wiring indicators; it reveals wiring conditions and can detect open neutral or open ground faults with a practical testing approach.
• Circuit Breaker Finder locates the correct breaker in the panel that corresponds to a tested outlet or fixture, helping you restore power quickly and safely.

Real-world scenarios

• Testing outlets after a remodel to confirm proper wiring and grounding before finishing walls.
• Locating the right breaker when a circuit trips, reducing guesswork and panel searches.
