Isolated ground (IG) systems have long been considered best practice for reducing noise (Electrical Noise on page C38) signals on the power supply of...More
The importance of bonding and grounding in commercial, industrial, and institutional buildings cannot be overstated. The grounded circuits of machines...More
You would think one of the most basic concepts of an electrical system would be the most widely understood. But after years of working in the electrical...More
Proper grounding and bonding prevent unwanted voltage on non-current-carrying metal objects, such as tool and appliance casings, raceways, and enclosures, as well as facilitate the correct operation of overcurrent devices....More
During the 2005 National Electrical Code (NEC) review cycle, a relatively simple revision was made that created a significant change on the cathodic protection (CP) systems of petroleum and chemical facilities (plants)....More
Reliable operation of security systems is obviously essential to protect company assets and ensure human safety. However, episodic equipment malfunctions...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.
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.
See side-by-side comparisons of different flame resistant fabrics exposed to flash fires, illustrating the extent, severity and location of burns....More
