Product Description
Milwaukee Digital GFCI Receptacle Tester and Voltage Detector with LED Kit
Model Number: 3211-20
The Milwaukee 3211-20 Digital GFCI Receptacle Tester and Voltage Detector with LED Kit is a two-piece electrical test kit built for the professional electrician, combining Milwaukee's non-contact Voltage Detector with LED Work Light (3202-20) and the Digital GFCI Receptacle Tester (2224-20) 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. Both tools ship ready to use with batteries included.
The Voltage Detector with LED 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, while an integrated independently operable LED work light gives the electrician illumination of the work area without requiring a separate flashlight, which is particularly useful in panels, junction boxes, attics, crawl spaces, and other low-light environments where most electrical troubleshooting actually happens. The reinforced tip design improves durability against repeated probe insertion, the quarter-turn battery cap simplifies field battery replacement, and the durable belt clip and over-molded grip make the detector practical to carry and use one-handed across a full work day.
The Digital GFCI Receptacle Tester plugs directly into a standard 120V receptacle and uses an LCD screen plus LED visual indicators to clearly identify the outlet's wiring condition: hot and ground reversed, hot and neutral reversed, open hot, open neutral, open ground, or correct wiring. The LCD display also shows live voltage at the outlet and trip time during a GFCI test cycle, which is essential information for any GFCI verification work that needs to be documented. 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 (the Voltage Detector is covered by a separate 1-year warranty). Together the kit gives an electrician the verification tools needed for new construction commissioning, service calls, renovation troubleshooting, and any work where confirming electrical safety conditions matters more than getting the job done fast.
