2. Turn circuit breaker OFF.
3. Remove and tag wires from circuit breaker (1) to be tested.
4. Using a multimeter set to read resistance (ohms Ω), check for continuity at circuit breaker (1) between
contacts (2). There should be a reading of infinity (Q).
5. If continuity is present, replace defective circuit breaker.
6. Turn circuit breaker ON.
7. Using a multimeter set to read resistance (ohms Ω), check for continuity at circuit breaker (1) between
contacts (2). There should be a reading of zero (0).
8. If no continuity is present, replace defective circuit breaker.
