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 amp 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.
Do not use the INSP-3 to test AFCI protection (Arc Fault Circuit Interrupter) on the following breaker: Eaton (Cutler Hammer) BRCAF120CS (20A)
Due to unique design of the AFCI protection, the INSP-3 is not able to trip it. The INSP-3 can perform all other tests on this breaker per user manual.
This is the only known breaker type that the INSP-3 has limitations with testing (tripping) AFCI protection.
