Solar Labels NEC 2020
NEC 2020 Solar Labels for Photovoltaic Systems (Article 690)
The 2020 National Electrical Code (NEC) Article 690 introduced updated requirements for labeling photovoltaic (PV) systems to improve electrical safety, hazard identification, and emergency response. These NEC 2020 solar warning labels and photovoltaic safety labels are used throughout PV installations to clearly mark energized equipment, DC conductors, rapid-shutdown systems, and system disconnects. Proper labeling helps electricians, inspectors, and first responders quickly recognize electrical hazards and safely service solar equipment. NEC 690 specifically governs the installation and safety requirements of solar PV systems and includes important marking rules for identifying PV power sources and system components.
NEC 2020 requires permanent, clearly visible labels on key PV system components such as service equipment, inverters, disconnects, and wiring systems containing DC conductors. Labels may indicate information such as maximum system voltage, the presence of photovoltaic power sources, and the location of rapid-shutdown devices used to de-energize the system in an emergency. These markings ensure technicians and emergency personnel can quickly identify power sources and understand the configuration of the solar installation.
PV Labels provides durable NEC 2020 photovoltaic warning labels designed for code-compliant solar installations, built to remain visible in demanding indoor and outdoor environments. These high-visibility safety labels help installers meet NEC labeling requirements while ensuring clear hazard communication for photovoltaic systems, electrical equipment, and interconnected power sources across residential, commercial, and industrial solar installations.
ANSI - All labels identified in the 2020 NEC are associated with this statement: "The warning sign(s) or label(s) shall comply with NEC 110.21B" ...NEC 110.21 - Marking (B): Field Applied Hazard Markings. Where caution, warning or danger signs or labels are required by this code, the labels shall meet the following requirements...the marking shall adequately warn of the hazard using effective words and/or colors and/or symbols and the label shall be sufficient durability to withstand the environment involved. Informational Note: ANSI Z535.4-2011, Product Safety Signs and Labels, provides guidelines for suitable font sizes, words, colors, symbols and location requirements for labels.
