Which NEC chapters cover general wiring applications?

The correct choice highlights Chapters 1-4 of the National Electrical Code (NEC), which address the foundational principles and general requirements governing wiring applications.

Chapter 1 introduces general provisions, setting the context for the entire Code and outlining the purpose of the NEC. Chapter 2 deals specifically with wiring and protection, detailing the standards and practices that apply to wiring methods and materials. Chapter 3 focuses on wiring methods and conductors, offering guidance on how electrical systems should be properly installed and maintained. Chapter 4 discusses equipment for general use, which includes the specifications surrounding devices and appliances that work with the wiring systems.

These chapters together form the base framework applicable to most wiring applications, ensuring safety and compliance in electrical installations. Hence, anyone preparing for the Class D Systems Technician License should have a strong grasp of the content within these chapters, as they provide the necessary knowledge for general electrical work.
