After repairing or replacing a component, what is the next step before returning to service according to the standard sequence?

• A. Verify interlocking state.
• B. Test individual components.
• C. Inspect wiring.
• D. Return to service.

Answer: (B)

Testing the individual components is the next step because it confirms that the repaired part operates correctly on its own before it interacts with the rest of the system. This isolated verification catches faults or misadjustments introduced during repair, ensuring the device responds to control signals as designed without interference from other parts of the circuit. Only after the component has passed these focused tests should you proceed to broader checks like wiring inspection and interlocking state verification to ensure the overall system integrates safely. Returning to service comes last, once all tests and verifications are complete and successful.
