All PV equipment must be grounded per NEC 250. Modern solar installations use several key safety components. Bonding connects metal equipment parts together to establish electrical continuity and prevent electric shock. This process involves two distinct but related concepts: system grounding, which provides a reference to earth for the electrical system (stabilizing. . These grounding loops (additional paths created by multiple ground rods) can interfere with the proper functioning of GFCI/AFCI devices. Similarly, high transient voltage and lightning strikes may damage interconnected equipment. }Figure 690–79 }Figure 690–79. . The NEC is the primary guiding document for the safe designing and installation practices of solar PV systems in the residential and commercial markets in the United States. Designing a reliable ground mounted solar racking system is not just about steel structures — it requires engineering. .
