What is a focus of Article 690?

• A. Industrial Machinery
• B. Sensitive Electronic Equipment
• C. Solar Photovoltaic (PV) Systems
• D. X-Ray Equipment

Answer: (C)

Article 690 of the National Electrical Code (NEC) specifically addresses the installation and safety requirements related to solar photovoltaic (PV) systems. This article provides guidelines for the design, installation, and maintenance of PV systems to ensure they operate safely and efficiently. It covers critical aspects such as equipment ratings, wiring methods, system grounding, and overcurrent protection that are unique to solar technology. By focusing on solar PV systems, Article 690 helps promote safe practices for electricians and engineers working with renewable energy sources, which have specific needs and challenges distinct from traditional electrical systems. The inclusion of requirements for both grid-connected and standalone systems ensures that PV installations are performed in compliance with safety standards, benefiting not only the property owners but also the broader community by facilitating renewable energy integration.
