Which section of the Code would most likely define "Conductor Material Type"?

The section of the Code that most likely defines "Conductor Material Type" is related to definitions and general requirements. In this context, Section 110.5 provides a comprehensive overview of terms and definitions essential for understanding the Code. This section is designed to clarify terminology essential for effective communication and application of the Code's provisions.

In contrast, section 100 typically offers definitions of fundamental terms used throughout the Code, but it may not focus specifically on conductor material types in the same depth as 110.5. Section 90.2 outlines the purpose and scope of the Code and addresses how it applies to electrical installations, which is broader and does not specifically target the material characteristics of conductors. Section 220.5 relates to load calculations and electrical demand factors, which are necessary for sizing conductors, but it does not cover material types directly.

Thus, Section 110.5 is aimed at defining specific technical attributes, making it the most appropriate choice for defining "Conductor Material Type."
