Why is "derating" important for conductors?

Derating is important for conductors because it takes into account various environmental factors that can affect their performance and safety, ultimately reducing the current-carrying capacity. Conductors may experience heat buildup due to factors such as elevated ambient temperatures, bundling with other conductors, or installation in locations with limited airflow. By derating, you ensure that the conductor operates within a safe temperature range, minimizing the risk of overheating, damage, or failure. This practice is crucial to maintaining the integrity of electrical systems and ensuring they operate safely and reliably under real-world conditions.
