For conductors rated 0 to 2,000 volts, where are ampacities specified?

The specified ampacities for conductors rated from 0 to 2,000 volts are indeed listed in the correct range, which includes Table 310.16 through Table 310.21. These tables provide essential information regarding the allowable ampacity of different sizes and types of conductors based on various installation conditions, such as temperature ratings and the number of conductors in a raceway.

Table 310.16 specifically covers the ampacity for conductors in common configurations under normal conditions. Subsequent tables within that range (310.17 to 310.21) address specific adjustments or conditions that may apply, such as adjustments for temperature and more specialized installation scenarios.

To summarize, the ampacities are detailed within this particular set of tables to ensure that they meet the safety and performance needs of electrical installations, validating that using this information allows electricians and engineers to select appropriate conductor sizes for their applications.
