For conductors rated between 2,001 to 35,000 volts, where should one look for ampacity specifications?

The correct answer highlights the importance of referring to specific tables that provide ampacity specifications for conductors within a certain voltage rating range, specifically between 2,001 to 35,000 volts. Table 311.60(C)(67) through Table 311.60(C)(86) is designated for conductors rated above 2,000 volts, which is critical for ensuring that installations comply with safety standards and operate efficiently.

When using these tables, it is essential to consider factors such as conductor material, insulation type, and installation conditions, which can all affect the ampacity of the conductors. This information is fundamental for electrical engineers and installers to correctly size conductors, preventing overheating and ensuring safe operation in high-voltage applications.

While other sources such as the NEC Appendix and manufacturer's guidelines may provide useful information, the tables specifically designed for ampacity under the National Electrical Code (NEC) give the most accurate and standardized data needed for conductors in this voltage class.
