What is the ampacity rating in degrees Celsius for conductors installed inside AC cable?

The ampacity rating for conductors installed inside AC cables specifically refers to the maximum amount of electric current the conductors can handle safely before their temperature rises to a point that could cause damage or a safety hazard.

In the case of conductors within AC cables, the rating corresponding to the typical insulation used, combined with common installation practices, aligns with a temperature rating of 60° C. This classification is crucial for electrical safety and ensures that the conductors do not exceed their thermal limits during operation, preventing potential overheating.

The other temperature ratings mentioned, such as 40° C, 75° C, and 90° C, relate to different scenarios or insulation types and are not specifically applicable to the ampacity of conductors in AC cables under standard conditions. Hence, 60° C stands out as the correct ampacity rating for this particular context.
