LEDs have unique and compelling characteristics that make them ideal for industrial lighting applications. But there are a variety of misconceptions about LEDs, how well they work, how long they last, and more. Digital Lumens developed this whitepaper to dish up the facts around LEDs and address some common misunderstandings....More
An arc flash is associated with the explosive release of energy caused by an electrical arc, due to either a phase-to-ground or a phase-to-phase fault. This kind of fault can result from many factors – a dropped tool, accidental contact with electrical systems, buildup of conductive dust, corrosion or improper work conditions.....More
Abstract: In this webinar, Mike will not only explain the current NEC requirements for GFCIs and AFCIs, but he'll explain how they operate, what causes their premature failure, and when they won't provide the safety protection you might have thought they would.
Abstract: This webinar will teach attendees the difference between risk and hazard, and how the choice of system grounding has a direct impact on reliability and safety.
