The Amprobe INSP-3 wiring inspector is a rugged tester designed to verify building wiring compliance to electrical code, especially voltage drop under load. Identify issues with splices, connections and conductor quality, crucial to safety and performance of the electrical system. The INSP-3 verifies if wiring is tested for load carrying ability that it meets electrical code recommendations for voltage drop under the load. The INSP-3 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
