In which NEC section are the requirements for overcurrent protection found?

The requirements for overcurrent protection are specifically detailed in NEC Article 240. This section provides guidelines regarding the protection of conductors and equipment from excessive currents, which can arise from short circuits, ground faults, or overload conditions. Article 240 outlines the necessary ampacity of conductors, specifies the ratings for overcurrent devices, and discusses the required protective measures to ensure safe electrical systems.

Understanding the principles in this article is crucial for ensuring that electrical systems can safely handle current fluctuations, which protects both the equipment and individuals from potential hazards. The other articles mentioned cover different topics, such as grounding and bonding (Article 250), conductors for residential applications (Article 320), and general requirements for electrical installations (Article 110), but none pertain directly to overcurrent protection like Article 240 does.
