What topic does Chapter 5 of the NEC primarily cover?

Chapter 5 of the National Electrical Code (NEC) primarily focuses on special occupancies. This chapter outlines specific rules and requirements that must be applied to electrical installations in various unique or specialized environments that may pose additional challenges or risks. Special occupancies might include areas such as theaters, hospitals, data centers, and hazardous locations, where traditional electrical practices might not suffice due to the nature of activities or materials involved.

The chapter provides guidelines to ensure electrical safety in these distinct spaces, considering factors such as the potential for fire hazards, the need for increased safety measures, and the presence of sensitive equipment. By framing the regulations with a focus on special occupancies, the NEC aims to account for the unique conditions that impact electrical installations, ensuring safety and compliance tailored to each type of environment.
