Equipment Grounding Conductors for Parallel Conductor Installations

by Michael Johnston

Equipment installed in electrical systems generally is required to be grounded. There are some specific exceptions that relax this general requirement of the NEC; but, for the most part, electrical equipment and the normally non-current-carrying metal (conductive) parts of equipment are to be grounded.

Perspectives on PV

* Inspectors Demand More Answers

by John Wiles

Electrical inspectors and other inspectors are curious people and when faced with reviewing plans for a PV system or inspecting such a system, there are many new features that are worth questioning. Here are some of the questions that inspectors have raised via e-mail, telephone calls, and during my PV/NEC presentations over the last four months. Read more

Critical Operations Power Systems

by Tim Owens

In September 2001, New York was horrified by the destruction of the World Trade Center due to terrorist activities.

Ask Not

by Wayne Lilly

By the time this article is printed, my year as international president will have ended. Brenda and I thank each of you for your kindnesses during the section meetings. My time working through the chairs at the chapter, section and international levels has given me friends that I will cherish all my life and has afforded me countless learning opportunities. It has provided me with an appreciation of the hard work done by the leadership throughout IAEI and taught me what it means to be part of an organization dedicated to high standards and goals that are meant to serve the best interest of our fellowmen.

Opening an Electrical Business? Don’t Give Up Financial Security

by Jesse Abercrombie

Last year, more than 670,000 businesses opened their doors, according to the U.S. Small Business Administration. In fact, hundreds of thousands of people set up their own shops every single year. If you’re considering startling your own electrical contracting or inspection firm, you’ve got a lot to be excited about, and you may be prepared to make large sacrifices to help your business succeed. But there’s one sacrifice you don’t have to make: your financial security. Read more

The Authority of the Electrical Inspector

by Michael Weitzel

All electrical inspectors have authority. The question is, How do they use it? Is it about their ego or about the work and safety for the customer? Authority is needed in society to establish order; otherwise, there is chaos. Inspectors have authority for a purpose: to protect people and property. Some inspectors have misused their authority. That’s not what inspecting is about. Every electrical wireman or installer can recall from personal experience an inspector that in his view was unreasonable, unapproachable, or seemed to abuse his or her authority. Hopefully, they can also recall an electrical inspector who was professional and who possessed great experience and education, as well as good people skills, that they enjoyed working with; maybe, they even learned something from that inspector! Being this kind of professional should be the goal of every inspector. Read more

Editorial

Opportunity is missed by most people because it comes disguised as work

by James W. Carpenter

September 9, 2006 — 250; October 20, 2006 — 262. After six weeks of traveling to all six section meetings that is how much weight I gained. Weight is not all I gained though. Each section meeting offered great educational opportunities in its own unique way. From presentations on Solar Photovoltaic and Fuel Cells Systems at the Northwestern Section; Code Breakfast and Code Panels at the Western Section; Breakout Sessions at the Canadian Section; Code Breakfasts and Analysis of Proposals for the 2008 NEC at the Eastern Section; Code Panel discussions at the Southern Section; to presentation on Fire Pump Installations and Swimming Pools and Spas at the Southwestern Section, education was the focus.
