In which section of the NEC would you find the rules for grounding and bonding?

The rules for grounding and bonding are found in Article 250 of the National Electrical Code (NEC). This article provides comprehensive guidelines on how to establish effective grounding systems, including requirements for grounding electrodes, equipment grounding conductors, and bonding practices necessary to ensure safety and reduce the risk of electrical shock and fire hazards.

Grounding is essential for protecting both people and property by providing a path for fault current to flow safely to the ground, whereas bonding ensures that all conductive materials are at the same electrical potential, preventing electrical shock from unexpected voltage differences. Article 250 elaborates on the specifics of these systems, detailing materials, installation methods, and testing requirements.

This focus on grounding and bonding in Article 250 helps to ensure that electrical systems are safe and reliable, adhering to the established safety standards set forth by the NEC. Other articles, such as Article 200, Article 300, and Article 400, cover different aspects of electrical installations but do not focus specifically on grounding and bonding.
