True or False: Tables for Chapter 9 in the NEC are legally enforceable by the AHJ.

The statement that tables for Chapter 9 in the National Electrical Code (NEC) are legally enforceable by the Authority Having Jurisdiction (AHJ) is false. While the NEC provides guidelines and standardized tables that outline various electrical installation requirements, these tables themselves do not possess inherent legal authority. Instead, enforcement of the NEC is dependent on local jurisdictions adopting the code and its specific provisions.

In many cases, jurisdictions may adopt the NEC as part of their local building codes, and it is these codes that carry legal enforceability. However, without explicit adoption, the tables and guidelines within the NEC do not automatically become enforceable regulations. Additionally, local amendments can further modify how the NEC is enforced within a jurisdiction, meaning not every table in the NEC would apply universally in all locations or situations. Thus, the role of the AHJ is crucial, as they interpret and enforce the adopted codes in their jurisdiction, but that does not confer legal status onto the NEC tables themselves without formal adoption procedures.
