Chapter 2 of the NEC primarily addresses which aspect of electrical installations?

Chapter 2 of the National Electrical Code (NEC) is primarily focused on wiring and protection. This chapter outlines the necessary requirements for safely installing wiring systems, including guidelines for protection against various hazards that can affect electrical installations. The chapter emphasizes the importance of using the right materials and methods to ensure that wiring is not only functional but also safe from physical damage, moisture, and other environmental factors that could potentially cause failures or hazards.

The concepts introduced in this chapter are foundational in setting up safe and effective electrical systems. It addresses considerations such as conductor sizing, insulation types, and overall installation practices that are crucial for maintaining safety and compliance with the NEC standards. Understanding wiring and protection ensures that installations perform effectively while minimizing risks associated with electrical faults.
