What does Article 705 deal with?

Article 705 of the National Electrical Code (NEC) specifically addresses interconnected electric power production sources. This includes systems such as solar photovoltaic (PV) systems, wind turbines, and other forms of distributed generation that connect to the primary electrical supply. The article provides guidelines for the safe and effective integration of these power sources with the existing electrical infrastructure, promoting safety, reliability, and performance.

This portion of the NEC is critical because it outlines requirements for interconnection, such as ensuring that power from these sources does not backfeed into the grid inappropriately and that there are proper disconnects and protections in place. It also addresses issues like synchronization, grounding, labeling, and proper installation practices, ensuring that both the interconnected generation source and the utility grid can operate harmoniously without endangering safety.

Understanding this article is essential for anyone involved in the installation or management of renewable energy systems or any technology that generates electricity and feeds it into a larger network, highlighting the need for compliance with these regulations to ensure safe operation.
