What does Article 240 mainly cover?

Article 240 primarily focuses on the requirements for overcurrent protection in electrical systems. This includes the selection, installation, and application of overcurrent protective devices, such as circuit breakers and fuses, which serve to protect electrical circuits from excessive currents that could lead to overheating and potential fires. Understanding the location of these protective devices is vital for ensuring safety and compliance with electrical codes, as proper placement can enhance the protection of the circuits from overloads and short circuits.

In context, while grounding requirements, load calculations, and voltage drop considerations are important in electrical design and safety, they fall under different sections of the electrical code and do not comprise the main focus of Article 240, which is dedicated specifically to the standards concerning overcurrent protective devices.
