AC/DC Voltage and GFCI Receptacle Outlet Test Kit


  • Electronic voltage tester is designed to test AC voltages from 24 to 240V AC at four useful levels
  • Tests DC voltages from 32 to 330V at four levels
  • Built-in test lead holder on back of voltage tester holds the leads in one of two positions: one so that they are spaced correctly to test tamper-resistant US-style outlets and the other for convenient storage of the test leads
  • Batteries not required; voltage tester is powered by the applied voltage
  • Voltage tester is rated CATIII 350V, Class 2, Double insulation and has IP44 ingress protection
  • Receptacle tester detects the most common wiring problems in standard and GFCI receptacles
  • Works on GFI outlets and confirms operation of the ground fault protective device
  • Nominal Voltage of receptacle tester: 110/125V AC at 50/60Hz in 3-wire outlet
