If on-site power is your sole source of power and you follow the NEC Art. 250, then grounding is straight forward. But, if it serves an alternate source, then grounding becomes much more complex....More
Most power quality problems are due to incorrect connections of an electrical system. Using CTs and leakage current monitors, you can check an electrical system during acceptance testing of the installation and also during maintenance and renovation of the system....More
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.
