NABCEP PV Installation Professional Practice Exam

Ground and bonding requirements for photovoltaic (PV) systems can be found primarily in Article 690 of the National Electrical Code (NEC), specifically in Part V, which deals with the other system requirements such as grounding and bonding. Article 250 also plays a crucial role, as it outlines general requirements for grounding and bonding applicable to all electrical systems, including PV systems.

The context of Article 250 is important because it provides the overarching rules for grounding and bonding for all electrical installations, ensuring safety and preventing electrical hazards. Article 690 Part V then specifies how these overarching rules apply specifically to PV systems, addressing unique aspects that need consideration due to the nature of solar energy technologies.

While other articles in the NEC address different aspects related to electrical installations and solar energy, they do not focus specifically on the ground and bonding requirements for PV systems in the comprehensive way that Article 690 and Article 250 do. Thus, the combination of both articles gives a complete picture of the requirements needed to ensure safe and effective grounding and bonding for PV installations.
