What does Section 690.5 address in PV systems?

Section 690.5 of the National Electrical Code (NEC) specifically addresses the wiring methods for direct current (DC) circuits in photovoltaic (PV) systems. This section provides guidelines related to the installation and configuration of wiring for DC circuits that are generated by solar panels.

Proper wiring methods are crucial in PV systems as they ensure safe operation and reduce the risk of electrical hazards. The section outlines requirements on how to properly size conductors, select appropriate materials, and lay out wiring to minimize losses and facilitate safe connections. Therefore, understanding Section 690.5 is vital for anyone involved in the design or installation of PV systems to ensure compliance with safety standards.

The other choices, while relevant to aspects of electrical systems, do not specifically relate to the particular focus of Section 690.5.
