Metal Solar Placards offer maximum durability and ease in code compliance. Perfect for solar applications, a special process seals metallic particles under a clear anodized layer, which results in markings that have been tested and rated to last up to 25 years in outdoor use, even in direct sunlight. Markers are designed to meet the latest National Electrical Code (NEC 2014), with pre-printed warning or caution messaging that conforms to Article 690, as well as ANSI guidelines. Pre-printed placards may be more acceptable to some local Authorities Having Jurisdiction (AHJs), who may have a preference for placard-style identification. Metal Solar Placard, WARNING ELECTRICAL SHOCK…, 3.75" x 2.0", AA, Orange/Silver, 5/pkg.
