In what part is the securing and supporting of Type AC, Type FC, Type MC, and Type NM cable addressed?

The correct answer identifies that the securing and supporting of Type AC, Type FC, Type MC, and Type NM cable is specifically addressed in Part II of the National Electrical Code (NEC). Part II includes detailed guidelines and requirements for the installation of conductors and cables, which directly pertains to the methods for securing and supporting these types of cables.

Understanding the structure of the NEC is crucial, as it organizes various electrical installations into distinct parts to provide clarity and focus on specific requirements. Part I typically covers general requirements and definitions, while Part III addresses specific installation methods and materials used beyond the securing methods. Part IV deals with additional provisions that may not be applicable to the basic handling of cable types. Therefore, focusing on Part II ensures that one is referencing the correct section that deals with the pertinent aspects of cable installation safety and compliance.
