The National Electrical Code (NEC) Section 690 outlines specific labeling requirements for photovoltaic (PV) systems to ensure safety and compliance. These requirements were updated in 2020. Visibility After Installation: Labels or markings must remain visible after installation, ensuring they can be easily read during maintenance or emergencies.
When labeling a Solar Photovoltaic (PV) system, it is necessary to label the primary utility meter to indicate the presence of a PV system. Additionally, DC junction boxes, combiner boxes, disconnects, AC disconnects, and connections to sub panels, inverters, etc. need to be labeled.
Proper safety labeling is a critical aspect of solar installation safety, helping to prevent accidents and injuries by clearly communicating potential hazards. By adhering to established standards such as ANSI Z535, NFPA 70E, OSHA's HCS, and NEC 690, solar installers and operators can ensure their systems are safe for everyone involved.
