Which code must all conductors comply with?

The National Electric Code (NEC) is the standard that governs the installation of electrical conductors and other electrical equipment in the United States. It sets the minimum safety requirements to protect people and property from electrical hazards. The NEC addresses a wide range of topics, including conductor sizing, insulation types, and overall safe installation practices.

Compliance with the NEC is crucial for ensuring electrical systems operate safely and efficiently, reducing the risk of fires, shocks, and other electrical hazards. The code is regularly updated to reflect new technologies and methods, ensuring that electrical installations evolve with advancements in the field.

While the other standards mentioned may pertain to various aspects of electrical equipment or specific applications, they do not replace the NEC when it comes to general conductor requirements.
