What does NEC Article 250 primarily deal with?

NEC Article 250 primarily focuses on grounding and bonding requirements, which are essential for ensuring electrical safety in installations. Grounding protects people and equipment from electrical faults by providing a low-resistance path for fault current to safely dissipate into the earth. This helps to minimize the risk of electric shock and fire hazards. The article covers various aspects of grounding, including the specifications for grounding conductors, electrodes, and the required bonding of conductive parts to ensure that all metallic structures are at the same electrical potential.

By understanding the requirements outlined in Article 250, electricians can implement effective grounding and bonding practices that enhance the safety and reliability of electrical systems. The other options, while important in their own right, do not encapsulate the primary focus of this specific article within the NEC.
