Milwaukee Tool 2202-20 50-1000 VAC Non-Contact Voltage Detector w/Work Light

The Milwaukee 2202-20 detects 50 to 1000 VAC without contact. That covers standard 120V and 240V residential and light commercial circuits as well as 277/480V gear found in commercial buildings. It will not read below 50 VAC, so low-voltage work like doorbell, thermostat, or 24V control wiring is outside its range.

Yes, the 2202-20 carries a Cat IV 1000 V safety rating, which Milwaukee states is safe for all applications including industrial. CAT IV is the service-entrance and utility-connection category, so it covers the meter, the service drop, and downstream panels rather than just branch circuits.

There is a green power-on indicator light that confirms the detector is live and functioning before you use it. That addresses the main hazard with any non-contact tester, a dead battery reading as a dead circuit. Best practice is still to prove it on a known live conductor first, but the green LED tells you the unit powered up correctly.

Two AAA batteries, and Milwaukee calls them out as easy to replace, so there is no sealed pack or charging to deal with. For a maintenance tech carrying this in a pocket all day, that means a spare pair of AAAs in the truck keeps it in service.

Yes. The 2202-20 includes an extra bright LED work light built into the tester, which is the difference-maker when you are checking conductors in an unlit basement, attic, or a panel in a dark mechanical room. Milwaukee also sells non-contact detectors without the light, so if you want the illumination, this is the model with it.

Milwaukee 2202-20 is the manufacturer part number for the 50-1000 VAC non-contact voltage detector with the built-in work light. Order by 2202-20 to be sure you get the lighted version rather than a plain detector.

A non-contact detector like the 2202-20 tells you whether energized AC is present in the 50-1000 VAC range, which is what you want for a fast go/no-go check before opening a device box or pulling a fixture. It does not give you a numeric reading, does not distinguish 120 from 480, and will not detect DC. For verifying an absence of voltage under a formal lockout/tagout procedure, most facility programs require a contact meter reading phase to phase and phase to ground. Carry the 2202-20 for quick checks and keep a meter for verification.

Operation is a rear push button, so you thumb it on with the same hand that holds the probe, and there is a pocket clip for storing it in a shirt or bib pocket. That is the setup electricians and MRO techs want for a tool that gets pulled out dozens of times a shift.
