Analysis of the 2002 NEC Changes by Phil Cox Adopted as law by many states, cities and local jurisdictions in the United States and abroad, the NEC is the benchmark for safe and efficient electrical installations. Understanding the changes to the 2002 NEC is critical to visualizing Code revisions.

Cooking Fires Press Release A study released by NFPA indicates that while fire deaths due to cooking equipment has increased, the number of home cooking fires has decreased to the lowest level in the nineteen years of the study. MC Cable Installations by Larry Watkins The definitions in Article 334 identifies Type MC cable as a factory assembly of one or more insulated circuit conductors enclosed in an armor of interlocking metal tape, or smooth or corrugated metallic sheath. Electrical Inspector and Fire Alarm Systems by Mark Campbell The electrical inspector and the fire alarm inspector have common goals and are encouraged to work together and learn how their skills will benefit each other.  Overcurrent Protection for Conductors by Michael Johnston Article 240 of the NEC details requirements for overcurrent protection for conductors. Arc-Fault Circuit Interrupters by David Dini The 2002 NEC will require a new electrical safety device, the arc-fault circuit interrupter (AFCI), for added protection in certain dwelling unit branch circuits.  Type AC Cable by UL The IAEI/UL Technical Advisory Panel (TAP) assigned a task group to review the grounding provided by metal raceway systems described in NEC Section 250-118, and focus on the use of the armor of Type AC cable as an effective equipment grounding path.

Editorial: The 2002 National Electrical Code by Philip H. Cox, CEO/Executive Director Work on the 2002 National Electrical Code has been completed. Those using the NEC will find a significant difference in the new edition. It is likely to take some adjustments to become fully familiar with the new Code.  Canadian Code: Grounding and Bonding Sensitive Electronic Equipment  by Leslie Stoch No doubt everyone has experienced the frustration of a PC computer crash, lockup or unreliable data. Their cause is often due to voltage noise, formally defined as "unwanted disturbances imposed upon a useful signal to obscure its information content." Transient power system voltages and high frequency leakage currents can result in such failures and other problems.  Other Code: What's Coming in 2002?  by David C. Young, PE The National Electrical Safety Code (NESC) is now on a five-year revision cycle. The 2002 edition will be published on August 1, 2001, and "shall become effective no later than 180 days following its publication date" (Rule 016). There are a lot of changes. Over the next few IAEI News issues, I will try to share with you what I see as the significant changes. 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. Ask CSA: Fire Protection Systems. What Inspectors & Regulators Should Know  (pdf) by CSA Group What should be the extent of involvement of an electrical regulator in the inspections of electrically connected life safety and fire protection systems?
