___ has the power to grant special permission, often involving exceptions to NEC® rules or other customary guidelines.

• A. The authority having jurisdiction
• B. NFPA
• C. OSHA
• D. any of these

Answer: (A)

The authority having jurisdiction has the power to grant special permission, such as variances or interpretations, to the NEC. This official—often the local electrical or building inspector, fire marshal, or other code official—reviews plans and field conditions and can approve deviations from strict NEC requirements when needed to safely accommodate a specific installation. They ensure any alternative method or equipment provides equivalent protection to the code’s intent, and approvals are typically documented through permits or field modifications. NFPA develops the standards but does not grant exceptions, and OSHA enforces safety regulations rather than issuing NEC variances.
