What table provides allowable ampacities of insulated conductors for ratings up to and including 2,000 volts?

The table that specifies the allowable ampacities of insulated conductors for ratings up to and including 2,000 volts is indeed found in 310.16. This table serves as a comprehensive resource for determining the maximum current-carrying capacity of various types of insulated conductors, taking into account factors such as the conductors' material, insulation type, and installation conditions.

Understanding the correct use of this table is critical for ensuring safety and compliance with electrical codes, as it helps to prevent overheating and possible failure of the electrical system. The information in this table is essential for electricians, engineers, and designers to select the appropriate conductor sizes for specific applications while maintaining adherence to code standards.

Other tables, such as those referenced in the incorrect options, serve different purposes. For instance, 310.10 and 310.15 include aspects related to conductor ampacity but focus on different contexts or additional factors affecting ampacity. However, 310.16 directly addresses the specific ampacities related to insulated conductors up to 2,000 volts, making it the authoritative source for the question posed.
