What is a main regulatory requirement for circuit breaker operation during service?

A primary regulatory requirement for circuit breaker operation during service is performing routine inspections and maintenance. This practice ensures that circuit breakers function correctly and safely, reducing the risk of failures that could lead to unsafe conditions or equipment damage. Regular inspections allow for the identification of wear, corrosion, or other issues that could affect performance, enabling timely corrective actions to be taken.

Routine maintenance also involves verifying that connections are tight, components are clean, and that the breaker operates as expected under various conditions. These activities contribute to the overall reliability of the electrical system and help comply with established safety standards and regulations, ensuring the integrity of the system is maintained over its operational life.
