NEC Solar Labeling Requirements
This NEC Solar Labeling Requirement Tool is designed to help solar contractors quickly find the code-compliant labels and placards required for their photovoltaic installations. This tool details the solar labels in the National Electrical Code produced by the National Fire Protection Association (NFPA). Both current and historical versions of the NFPA 70 can be accessed on the NFPA website.
The NEC sets the mandatory wording, placement, and visibility of solar labels used to identify energized circuits, disconnecting means, rapid shutdown systems, and PV equipment.
