National Fire Protection Association (NFPA) Board of Directors voted unanimously to name Jim Pauley of Lexington, Kentucky, as the next president of NFPA. Pauley is currently senior vice president of External Affairs and Government Relations for Schneider Electric and will assume his new role in July. Read more



In principle, this subject appears to be quite simple; however, reality has demonstrated many inconsistencies in its application by the electrical designers and regulators. The biggest issue of such inconsistency relates to the fact that a technical enforcement of the requirements for electrical supervision of this electrically connected life safety equipment is done by various AHJs (sometimes by building inspection departments, sometimes by fire inspection departments, and occasionally – by electrical inspectors); and these various AHJs do not always use the same criteria for enforcement of such requirements. Read more 


Back in 1835, the first constant electric light was demonstrated; the lighting industry was born and has been changing ever since. Our electrical industry has seen many technology changes over the past 40 years with introductions and growth of ground-fault circuit interrupters (GFCI), arc-fault circuit interrupters (AFCI), photovoltaics (PV), electric vehicles (EV), wind generation and more. Solid-state lighting is another new technology that is blossoming as we speak. Walk with me, if you will, for a quick review of  LED lighting. Read more 


Continuous improvement is a way of life for any business and is accepted as a standard approach in improving quality, productivity and processes. At the core of continuous improvement is defining root causes, planning and executing preventative action to eliminate the potential issue, and deploying technology and practices that minimize the impact of any issue or hazard. This approach to continuous improvement can be extended to electrical safety and is sorely needed. Read more 


This article will take you through the electrical construction of a nine-story high-rise structure with parking at three floors down and four floors up. We will start at the bottom with the concrete-encased electrode (Ufer) and go all the way up to the first cup of coffee. We will show you both the complexity of the service and the simplicity of the receptacles. This installation is being reviewed under the purview of the 2011 National Electrical Code and other applicable codes. Read more 


As  we continue in the 2011 NEC Chapter 3, we are now to the point where we have specialized articles related to specific wiring methods. Here we will depart from covering each article and, instead, cover just the ones which are most commonly seen during the inspections we do most often. Read more


The current Canadian Electrical Code Part I (CE Code) has special terminology for a high voltage station that states, “Station – an assemblage of equipment at one place, including any necessary housing, for the conversion or transformation of electrical energy and for connection between two or more circuits.” This special terminology has remained unchanged since introduction in the fourteenth edition of the CE Code, dated 1982. Read more 


To have a safe and reliable electrical system that will be around for many years, one must first begin with a proper code-compliant installation. Using the proper products or materials within the proper environment is essential to its longevity. How often do we see electrical installations that have failed prematurely due to the use of a product not specified for its installation? Read more


My article, “Vending Machines,” in the January-February 2014 issue, may have left the false impression that an electrical shock hazard could not possibly happen at a soft drink cabinet just because it does not meet the definition of a vending machine. Read more 


I consider myself fortunate to have the opportunity to travel throughout the United States, Canada, and to other international designations both on business and for personal travel. What is fun and exciting is getting to meet people from diverse backgrounds and also to observe and learn new traditions and cultures. Read more 


How do we know who has Listing (certification) for a product category in the White Book? Read more
