What is the primary focus of Article 250 in the National Electrical Code?

Article 250 of the National Electrical Code is primarily focused on grounding and bonding. This article provides essential requirements for the safe and effective grounding of electrical systems. Grounding refers to the practice of connecting electrical systems to the earth, which helps prevent electrical shock and ensures that electrical systems operate safely in the event of a fault. Bonding, on the other hand, involves connecting various conductive parts to ensure that they have the same electrical potential, reducing the risk of electrical shock and fire hazards.

The requirements outlined in Article 250 are critical for establishing a reliable grounding system that mitigates the risks associated with electrical faults. This includes specifications for grounding electrodes, grounding conductors, and the methods used to ensure that all parts of an electrical system are properly bonded together.

While services, feeders, and branch circuits are all vital components of an electrical system, they are covered under different articles within the NEC, each addressing different aspects of electrical infrastructure. Therefore, the focus of Article 250 on grounding and bonding is essential for the safety and reliability of electrical installations.
