Which section of the NEC addresses the temperature correction and adjustment factors for conductor ampacity?

The section of the National Electrical Code (NEC) that specifically addresses the temperature correction and adjustment factors for conductor ampacity is indeed 310.15(A). This section provides guidelines on how to adjust the ampacity of conductors based on temperature conditions. It is crucial to consider these factors as the ampacity rating of conductors can vary significantly with temperature variations.

When conductors operate at temperatures above standard conditions, their ability to carry current without overheating is reduced. Therefore, NEC 310.15(A) establishes methods to apply correction factors, ensuring safe and efficient operation of electrical installations.

The other sections, while important in their own rights, focus on different aspects. For instance, 110.14(C) deals with temperature limits and the requirements for terminals and conductors, whereas 310.3(C) pertains to residential installations, and 310.6 addresses specific applications of conductors. However, for the purpose of temperature correction in ampacity specifically, 310.15(A) is the applicable section.
