Which statement is true regarding exceptions?

The statement regarding exceptions that is true is that exceptions apply to an entire article. This means that when an exception is established within a certain article of the National Electrical Code (NEC), it provides specific conditions or situations where the general rules set forth in that article do not apply. Thus, the scope of the exception influences how the provisions of that article are interpreted and can modify the general requirements for that entire section.

For instance, if a particular article outlines safety standards for electrical installations but includes an exception, that exception clarifies specific circumstances under which certain requirements may be waived or modified. Understanding this concept is crucial for ensuring compliance with the NEC while recognizing special circumstances where deviations from the standard practice are permissible.

In contrast, the other options fail to capture the nature of exceptions correctly. The claim that exceptions apply to all articles in the NEC is inaccurate, as each exception is relevant only to the specific article in which it appears. Moreover, stating that exceptions can be ignored or are not applicable contradicts the essence of their purpose: exceptions are part of the code and must be understood and followed within their defined contexts.
