What is the voltage rating of conductors covered by Table 310.16?

The correct voltage rating for conductors covered by Table 310.16 is up to and including 1,000 V. This table is part of the National Electrical Code (NEC) and provides guidance for the ampacity of conductors. It specifically applies to conductors rated for use at voltages up to 1,000 volts.

Options indicating higher voltage levels, such as 1,500 V or 2,000 V, do not apply to the ampacity calculations in Table 310.16. For conductors used in systems exceeding 1,000 V, different tables and considerations would be necessary, which is why it's crucial to reference the correct sections of the NEC for specific applications involving higher voltages. Understanding these limitations helps ensure compliance with electrical regulations and safety standards.
