Product Description
Milwaukee Non-Contact Voltage Detector
Model Number: 3200-20
The Milwaukee 3200-20 Non-Contact Voltage Detector is Milwaukee's professional-grade voltage tester designed for electricians, maintenance technicians, HVAC techs, plumbers, and any tradesperson who needs to quickly and safely confirm whether a conductor, fixture, outlet, or electrical component is energized before working on it. This is the latest generation voltage detector in Milwaukee's lineup, replacing the older 2200-20 with upgraded IP54 water and dust protection and an extended 2-year warranty (up from the previous 1-year). The detector identifies AC voltage between 50V and 1000V across the full range of residential, commercial, and industrial applications including outlets, switches, junction boxes, breaker panels, lighting circuits, motor connections, and service entrance work. A red LED indicator and audible tone fire simultaneously when voltage is detected, giving the operator clear, immediate, and unmistakable confirmation that a conductor is live and not safe to handle.
The defining safety specification of the 3200-20 is its CAT IV 1000V rating, which is the highest safety classification in the industry for non-contact voltage detection. CAT IV classification means the tool is rated for safe use on the source side of the service entrance, including utility connections, transformers, and primary distribution wiring where transient overvoltages can be most severe. Lower-rated detectors carrying CAT II or CAT III ratings cannot be used safely on these high-energy applications. The reinforced tip design improves durability against the repeated probe insertion the tool experiences across receptacles, junction boxes, breaker panels, and other test points throughout a workday, while the new IP54 rating means the detector continues to function reliably in dusty, dirty, and damp jobsite environments where conventional voltage testers would fail.
The 3200-20 includes practical features built around real electrical work, including a durable side-mounted belt clip for compact carry alongside other pocket tools, a quarter-turn cap design that lets the operator replace the (2) AAA batteries in the field without separate tools, and a battery test feature that confirms the detector has sufficient power for safe operation before each use. The detector ships with batteries included and is ready to use directly out of the package. For users who need integrated work-area illumination in addition to voltage detection, the Milwaukee 3202-20 Voltage Detector with LED Work Light is the same tool with an independently operable LED added to the body. For users who need both voltage detection and GFCI receptacle testing, the Milwaukee 3210-20 and 3211-20 kits pair a voltage detector with a GFCI receptacle tester. All Milwaukee voltage detectors are backed by a 2-year limited warranty against material and workmanship defects.
