Which article in the NEC pertains to Solar Photovoltaic Systems?

The correct choice is Article 690, which specifically addresses Solar Photovoltaic (PV) Systems within the National Electrical Code (NEC). This article covers the necessary requirements for the installation, connection, and safety of solar energy systems, ensuring that installations are performed correctly and safely.

Article 690 includes provisions for conductors, overcurrent protection, grounding, and interactive systems, specifically designed for the unique characteristics and challenges of solar PV technology. This regulation is critical as it helps ensure that solar installations are compliant with national standards and encourages safe practices.

Other articles listed, such as 430, pertain to motors, while 702 and 700 focus on optional standby systems and emergency systems, respectively. These do not deal with solar photovoltaic systems, which is why they do not pertain to this question. Understanding the specific jurisdiction of each article in the NEC helps in navigating code requirements efficiently, especially for electrical professionals dealing with renewable energy technologies.
