This article is dedicated to grounding and bonding, laying out where grounding conductors and bonds can be made and which methods are allowed. It covers the grounding electrode system, electrode conductors, bonding of metal parts and enclosures, and the use of equipment grounding conductors to create a low-impedance path for fault currents. Other articles focus on different topics (general installation rules, cords, hazardous locations, etc.), while Article 250 specifically governs how grounding connections are located and how grounding is done, making it the correct reference.
