The Challenge to Having Global Codes and Standards   by Jim Pauley, P.E.  There has been an increasing emphasis in recent decades to achieve international codes and standards for electrical installations and products. Although the benefits of unified documents and products worldwide seem obvious, the migration to such internationalization requires management that considers regional differences of elements such as: the presently installed base, practices used in construction, infrastructure and expectations of users.

What Does the Falling Dollar Mean to You?  by Jesse Abercrombie You may find that the declining dollar presents you with both opportunities and challenges. Can the falling dollar be a good thing, and what does it mean to you as an individual investor? Residential Electrical System Aging Research Project by Kathleen Almand The Residential Electrical System Aging Research Project will provide critical information to code writers—especially for NFPA 73 and the NEC—as well as AHJs, electrical equipment manufacturers, installers, property owners, and insurers. The overall goal of the project is to characterize the condition of various age groups of residential electrical systems, by surveying a representative sample of actual installed systems, and to document how aging and installation may relate to residential electrical fire experience. Bonding Metal Piping Systems by Michael J. Johnston Article 250 of the National Electrical Code provides the minimum requirements for grounding and bonding. In the past, it seems many viewed the word grounding as an umbrella description, and viewed the concepts for both bonding and grounding rules under the derivative of the word ground. This is probably why there are some very apparent misunderstandings about grounding and bonding, and which rules apply when.  Perspectives on PV: Neither Sleet nor Snow nor Rain nor the Dark of Night...     by John Wiles These and other weather conditions also affect how a PV system is designed and installed to comply with the requirements of the National Electrical Code. With a PV power system lifetime exceeding 40 years, Mother Nature is going to use every trick in the book to make that system fail before its time.

Editorial: The Prime Directive  by Gaylen Rogers, 2005 International President What do you think when someone asks, "Have you seen a good electrical inspector?" Do you reply that you see one in the mirror every morning? What principle or obligation does an electrical inspector consider as his or her "prime objective?" Canadian Code: CEC/NEC—Some Significant Differences  by Leslie Stoch Both our Canadian Electrical Code (CEC) and the U.S. National Electrical Code (NEC), when followed, are designed to eliminate undue electrical fire and shock hazards in electrical installations. Our intentions are identical to those of our neighbours. Our electrical codes vary only in the details and sometimes in how the rules are applied. We discussed some of the differences between the CEC and the NEC in earlier articles. In this one, let’s look at a few more. Electricity Fundamentals: Basic Electricity—Part 9  by David C. Young, PE It is time to bite the bullet. Before we can continue into three-phase electrical circuits and calculations, we have to have a solid understanding of voltage and current phase angles. To do this we turn to phasors.  UL Question Corner (pdf) by Underwriters Laboratories As families begin to clean up after a flood, there may be hidden electrical hazards. Inspectors Corner: Fire Pumps Application and Installation Requirements  by Ark Tsisserev The CE Code, Part I governs installation of various electrical equipment. A fire pump is certainly also covered by the Code requirements. But in addition to the CEC, Part I, this type of electrical equipment must meet provisions of other important documents.
