The National Electrical Manufacturers Association (NEMA) has published NEMA LSD 80-2018 Installation Guidelines for Outdoor Luminaires—Grounding Considerations. This white paper addresses the application of the National Electrical Safety Code® (NESC) as it pertains to the grounding of outdoor luminaires and recommends installation guidelines.
New outdoor luminaries contain more electronics (LED lamps, electronic drivers, and electronic lighting controls) than previous outdoor lighting technologies. Electronics are more sensitive to grounding and wiring issues than earlier technologies.
“This whitepaper offers guidelines on proper grounding techniques to improve outdoor luminary performance,” says Michael O’Boyle, technical policy manager, Signify.
