Which NEC article deals with Grounding and Bonding?

Article 250 of the National Electrical Code (NEC) is focused on Grounding and Bonding, which are critical components in ensuring the safety and reliability of electrical systems. Grounding refers to the process of connecting electrical equipment to the earth, providing a safe path for fault currents and helping to prevent electric shock hazards. Bonding, on the other hand, involves connecting various metal parts together to ensure that they maintain the same electrical potential, thereby reducing the risk of electric shock and ensuring proper operation of protective devices.

Understanding the concepts outlined in Article 250 is essential for electrical contractors and professionals, as proper grounding and bonding practices are vital for system performance and compliance with safety regulations. The code specifies requirements for grounding electrodes, equipment grounding conductors, and bonding of various systems, emphasizing the importance of these practices in preventing overvoltage conditions and ensuring effective circuit protection.

The other articles mentioned do not pertain to grounding and bonding; they cover different electrical topics such as overcurrent protection (Article 240), conductors (Article 260), and surge protective devices (Article 270), which although important, do not specifically address the critical aspects of grounding and bonding.
