Chapter 1 of the NEC covers what topic?

Chapter 1 of the National Electrical Code (NEC) addresses general provisions that apply throughout the entire code, including definitions, administration, and the intent of the code. This chapter lays down the framework for the standards that follow in subsequent chapters, which focus on specific systems and components. The general requirements apply to all electrical installations and provide guidance on safety and compliance.

While other chapters, such as those dealing with wiring methods, transformers, and fire pumps, focus on specific aspects of electrical installations, Chapter 1 is foundational and presents the overarching principles that regulate the entire code. It sets the stage for understanding how the NEC should be applied and understood in practice.
