Amprobe Instruments INSP-3 Wiring Inspector Circuit Tester


The Amprobe INSP-3 wiring inspector is a rugged circuit tester designed to test whether a building’s wiring is in compliance with electrical code in seconds, especially voltage drop under load. Without scrolling or switching screens, you can quickly identify issues with splices, connections and conductor quality, crucial to safety and performance of the electrical system. The flashing screen on this circuit tester will clearly indicate incorrect wiring or failures and it won’t trip circuit breakers or blow fuses during the test.


  • Testing efficiency - relevant test data (voltage, voltage drop, hot and neutral voltage drop, voltage with load, ground impedance) is presented on a single large display to save operator time - no scrolling or switching screens needed
  • Verifies if wiring is tested for load carrying ability that it meets electrical code recommendations for voltage drop under load
  • Meter detects faulty wiring in need of repair without removing outlets cover plates, or panel covers:
    • Faulty splices and connections
    • Incorrect wiring
    • Undersized wiring
    • Faulty GFCIs
    • Faulty or incorrectly wired AFCIs
    • Incorrect line voltage
    • Poor ground quality
  • User selectable 0, 10, 15 and 20 amps loads to verify performance of the electrical system
  • Incorrect wiring or voltage drop test failure is clearly indicated by flashing screen
  • Will not trip circuit breakers or blow fuses during the test
  • Tests GFCI and AFCI operations
  • Check ground quality for safety and ability to support sensitive electronic equipment
  • Measure fault currents
  • Save money and time by eliminating guess work
  • NOTE: The INSP-3 does not check the condition of wiring insulation.
