The physical properties of a No. 4/0 copper conductor would be found in which part of the NEC?

The physical properties of a No. 4/0 copper conductor are found in Chapter 9, Table 8 of the National Electrical Code (NEC). This table provides necessary information regarding the ampacity, resistance, and various other characteristics of conductors based on their size and type.

Chapter 9 primarily deals with the tables that outline conductor properties and is an essential reference for understanding how conductors perform under various conditions. Table 8, specifically, lists the physical and electrical properties of copper and aluminum conductors, including the gauge sizes up to 4/0. This information is critical for electrical design and ensuring compliance with safety standards.

While other chapters in the NEC cover topics relevant to electrical installations, they do not specifically focus on the physical properties of conductors in the way that Chapter 9 does. For instance, Chapter 6 deals with special installations and occupancies, Chapter 7 covers special conditions, and Chapter 8 pertains to communications systems. Thus, Chapter 9, Table 8 is the correct reference for understanding the properties of conductors like the No. 4/0 copper conductor.
