In terms of compliance, which code should be followed where local regulations are not more stringent?

The National Electrical Safety Code (NESC) is the correct code to follow in terms of compliance where local regulations are not more stringent. This code specifically addresses the safety of electric utility operations and provides guidelines aimed at protecting the safety of the electrical worker and the public in the context of overhead and underground electric supply installations.

While the National Fire Protection Association Code focuses on fire prevention and safety, the National Electrical Code acts as a standard for electrical wiring and installations, and the National Building Code pertains to construction and building safety standards. However, when it comes to electric utilities and the safety of electrical systems, the NESC is essential, especially in ensuring that utility operations conform to safety protocols to prevent accidents and ensure reliable service. Therefore, in environments where local regulations do not impose stricter guidelines, adherence to the NESC is crucial for compliance and safety in electrical operations.
