In considering whether a circuit breaker is suitable for further service after it has interrupted a fault, it is important to understand the fundamental function and safety considerations associated with circuit breakers. When a circuit breaker opens due to a fault, it is designed to protect the electrical system and prevent damage. However, the act of tripping does put stress on the breaker, and there is potential for damage or wear, which might not be visible.

The information outlined in the NFPA 70E emphasizes the necessity of inspecting and testing circuit breakers after they have been tripped to ensure they function properly and safely. Without proper evaluation, the risk of a malfunction during future use increases. Therefore, stating that a breaker is "not suitable for further service" after a fault interruption is more aligned with safety best practices, as it inherently implies that further inspection and testing are necessary to determine its condition before it can be deemed safe for use again.

As a result, asserting that it is false to say that a circuit breaker might still be suitable for further service underscores a critical safety mindset that prioritizes thorough assessment over assumption post-event. The importance of safety inspections and testing to ensure functionality of electrical components after their protective measures have been engaged aligns with NFPA 70E's commitment to
