The rugged Amprobe INSP-3 Wiring Inspector Circuit Tester verifies in seconds whether a building’s wiring (including voltage drop under load) complies with electrical code. This saves time and money by eliminating guess work. The large display shows all relevant test data so you can quickly identify issues with splices, connections, and conductor quality that are crucial to safety and performance, without scrolling or switching screens. Select a 10, 15, or 20 A load on the electricity tester then read the results. A flashing screen clearly indicates incorrect wiring or failures. This wire tester won’t trip circuit breakers or blow fuses during the test.

The INSP-3 circuit tester comes with a power cord, one 9 V alkaline battery (installed), user's manual, and a carrying case.


• Presents relevant test data (voltage, voltage drop, hot and neutral voltage drop, voltage with load, ground impedance) on a single large display to save operator time. No scrolling or switching screens needed
• Verifies that wiring tested for load carrying ability meets electrical code recommendations for voltage drop under load
• Detects faulty wiring without removing outlets cover plates or panel covers
• Finds most common wiring problems, including:
