The NEC article number associated with grounding is?

• A. 250
• B. 100
• C. 200
• D. 300

Answer: (A)

Grounding and bonding are addressed in NEC Article 250. This section lays out how to establish a grounding electrode system (like ground rods or plates), how to connect equipment grounding conductors from devices back to that system, and how to bond exposed metal parts so they all share the same electrical potential. The purpose is to give fault currents a low-impedance path back to the source to trip protective devices and to minimize shock hazards by preventing dangerous differences in potential. You’ll find guidance on sizing conductors, bonding water and gas piping, and the proper use of grounding clamps and electrodes. Other NEC chapters cover different topics, but grounding and bonding are centralized in this article, which is why that article number is the one associated with grounding.
