The Milwaukee 3210-20 is a professional-grade combo kit that pairs a voltage detector with a GFCI receptacle tester, essential tools for electricians working in residential, commercial, and industrial settings. The voltage detector carries a CAT IV 1000-Volt safety rating and detects AC voltage from 50V to 1000V. A red LED and audible alert confirm voltage presence instantly. It runs on two included AAA batteries. The GFCI tester lowers electrical shock risk by verifying outlet safety. An over-molded grip provides durability and comfort during extended use. LED indicators show wiring conditions at a glance, identifying hot/ground reversed, hot/neutral reversed, open hot, open neutral, open ground, or correct wiring. Made for reliability and speed on the job.
