Three Chiefs Come Full Circle on Parallel Paths and End on a Tangent by Xen George Anchales, Tom Trainor, and Connie Golovko Proper grounding and bonding are critical elements in a safe electrical installation. All inspectors and installers are encouraged to review the "new" Article 250 and become familiar with the significant changes. Grounding of Alternate Power by Rene Castenschiold, P.E. When engine generator sets are used as an alternate source of power (i.e., emergency or standby power), it is essential that they be properly grounded and that associated transfer switches be properly selected. Navigating the Ground Rod Electrode Maze by David C. Prior Bear in mind that the purpose of grounding is primarily to protect (1) personal safety, (2) system reliability, and (3) equipment. To imply that a particular ground rod electrode is universally desirable is simply not good engineering judgment.

Arc-fault Circuit Interrupters—a Critical NEC 2005 Issue by Brendan Foley, Joseph Engel, and Clive Kimblin Eaton Electrical advises that the code language should not be changed to reference a specific type of AFCI. The code panel could certainly revisit this subject in future code cycles when combination AFCIs have become commercially available, and if practical field experience indicates superior fire protection capabilities without unwanted tripping. Neon Secondary Circuits Over 1000 Volts by Michael J. Johnston This article focuses on the general requirements for neon secondary circuit conductor installations from the high voltage hub or connection at transformer or supply to the first electrode in the tubing installation. Staying Ahead of the Curve by Steve Campolo The introduction of modern electrical and electronic technology into the home has drawn electrical device manufacturers closer to the electrical inspection community and safety organizations.

Editorial: IO President's Farewell Address  by Ray Weber, 2003 International President I have given my editorial space for this issue of the IAEI News to our International President, Ray Weber. Ray’s term of office concludes with the November Board of Directors’ meeting. It is fitting to provide to the outgoing international president a forum for remarks relative to the long journey to the presidency and the change to challenge the rest of us for the future. —Jim Carpenter Canadian Code: Reduced Size Taps Rule 14-100, Reduced Wiring Ampacities  by Leslie Stoch This article will discuss Rule 14-100, which specifies the minimum requirements for reductions in wire sizes. Splitter box connections are among the most common applications of Rule 14-100, where conductor sizes are reduced to current ratings below the fuse or circuit-breaker settings protecting the larger conductors. Other Code: Delayed Accident Investigations   by David C. Young, PE About twenty times each year, I am consulted on accidents involving our electric power delivery system. Most of them are accidents involving property damage. The following are some examples of this type of accident: a house fire that appears to be of electrical origin, a truck is damaged when hitting wires, a truck hits a anchor guy which results in two poles breaking and three spans of wire and equipment falling to the ground, appliances burning up when a high voltage line drops on to a lower voltage line.  UL Question Corner  (pdf) by Underwriters Laboratories The “UL Question Corner” answers questions of general interest that are sent in from authorized government inspectors and we believe will have interest for many inspectors.
