Product Description
Milwaukee GFCI Receptacle Tester and Voltage Detector Kit
Model Number: 3210-20
The Milwaukee 3210-20 GFCI Receptacle Tester and Voltage Detector Kit is a two-piece electrical test kit built for professional electricians, pairing Milwaukee's non-contact Voltage Detector (2200-20) with the GFCI Receptacle Tester (2223-20) into one essential troubleshooting and verification package. The kit covers the two most common day-to-day electrical safety checks: confirming whether a conductor or fixture is energized before working on it, and verifying that a receptacle is correctly wired and that its GFCI protection is functioning. Both tools are designed for residential, commercial, and industrial applications and are built to withstand the abuse of regular jobsite use, including a tested 6 ft. drop rating on each piece. The Voltage Detector ships with batteries included, ready to use out of the box.
The Voltage Detector carries the highest safety rating in the industry at CAT IV 1000V, detecting a wide 50V to 1000V AC range across non-contact testing scenarios from low-voltage control wiring through full-voltage service entrance work. A red LED indicator and audible tone fire when voltage is detected, giving the operator clear, immediate confirmation that a conductor is energized. The reinforced tip design improves durability against repeated probe insertion into outlets, junction boxes, and breaker panels, while the durable over-molded grip and compact pocket-clip form factor make the detector practical for one-handed use throughout the workday. The detector requires two AAA batteries which are included in the kit, and is backed by a 1-year warranty.
The GFCI Receptacle Tester plugs directly into a standard 120V receptacle and uses LED visual indicators to identify the outlet's wiring condition, including hot and ground reversed, hot and neutral reversed, open hot, open neutral, open ground, and correct wiring. The tester does not require batteries since it draws power from the receptacle itself during the test. Activating the test button on a properly wired GFCI outlet trips the device, and the visual indicator confirms whether GFCI protection is functioning correctly. The tester carries a CAT II 300V safety rating appropriate for receptacle-level work and is covered by a 2-year warranty, while the Voltage Detector is covered by a separate 1-year warranty. For users who need an LCD display showing live voltage and trip time data, the Digital version of this kit (Milwaukee 3211-20 with LED work light on the voltage detector) is available as a separate listing. Together this kit gives an electrician the essential verification tools needed for service calls, new construction commissioning, renovation troubleshooting, and any work where confirming electrical safety conditions matters more than getting the job done fast.
