Report: NFPA Electrical Inspector’s Forum

by IAEI

The National Fire Protection Association, by action of the Board of Directors chaired by George Ockuly,hosted a meeting and forum of electrical inspectors on May 22 – 23, 2006, at NFPA Headquarters, Quincy, Massachusetts. Mark Earley and the electrical division brought thirty-three electrical inspectors from across the United States to spend two days addressing: 1) enforcement officials’ critical needs, and 2) ways to elevate the professional status of the electrical inspector. This gathering of electrical inspectors was unique in that they were not there to discuss technical NEC issues. Read more

Perspectives on PV

* PV Systems and Workmanship

by John Wiles

With electrical systems lifetimes exceeding forty years, PV systems must be installed using the best available workmanship to ensure public safety over the life of the system. Article 110, Requirements for Electrical Installations, and particularly Section 110.12, Mechanical Execution of Work, of the National Electrical Code (NEC) establish some general requirements for the installation of electrical equipment. A fine print note (FPN) to Section 110.12 references the National Electrical Contractors Association standard ANSI/NECA 1-2000 (latest edition is 2006) as describing accepted industry practices for electrical installations. This article will illustrate some areas that need attention when the workmanship of PV installations is being inspected. Of course, the local authority having jurisdiction (AHJ) determines what is acceptable. Read more

Pre-Alt Inspections

by George Anchales

The National Fire Protection Association estimates there are 111,400 fires annually caused by faulty electrical distribution systems, electrical appliances and equipment. These fires caused 3,785 injuries, 860 deaths and nearly $1.3 billion in property damage. Older electrical systems, combined with greater power consumption, have probably contributed to this problem.

Case Study: Arizona Cardinals’ new state-of-the-art retractable stadium roof

by Michael W. Vallier

As professional sports venues become bigger and more complex in design and scale, architects and engineers are looking for bold new ideas. Retractable roofs have become a popular feature in those structures because they provide the ability to control the stadium’s interior environment more effectively. Read more

The Value of Electrical Inspection

by Michael Johnston

There is significant intangible value in many of the things we take for granted. For example, essential resources such as the air we breathe and the water we drink and use are often taken for granted. Society expects these life essentials to be safe, and not much thought is given to how safe they really are. Only when an identified problem surfaces, do people get concerned and fear sets in.

What Do the Markings on Circuit Breakers Mean?

by Ed Larsen

Have you ever been confused about what the markings on circuit breakers mean? Understanding the markings on electrical equipment is a fundamental need to ensure a safe and reliable electrical installation. Circuit breaker marking requirements are established by the requirements found in the NEC and the UL 489 product standard. Read more

Temporary Services – an anything goes situation?

by Michael Weitzel

In most areas of the country, building construction is booming, and there is a huge need for and use of temporary construction power. As electrical inspectors and installers in the field, we either inspect, install, or otherwise work with these types of installations frequently, if not daily.Read more

The Dream

by Wayne Lilly

By the time this editorial appears in the IAEI News my year as international president will almost be over. As most would do at this time, I am reflective about my years with IAEI and about IAEI then and now. It is said that the longest journey begins with a single step. Looking back over the years, we can trace the steps IAEI has taken to be where it is today. Read more

Electrical Safety In Health Care Facilities, Canadian Perspective – What Should We Know?

by Ark Tsisserev

Which areas of a health care facility electrical system must be tested for voltage difference between ground points, for ground return path voltage rise — in grounded systems or for test of impedance to ground — in isolated systems? Which loads of an electrical system in a health care facility are considered to be essential system loads and what kind of the power supply must be provided to these loads? Read more

Electrical Inspectors

by David Young

Two readers have e-mailed me with the question, "Is there a test I can take to become a certified National Electrical Safety Code‚ (NESC‚) inspector?” The short answer is, no. There are no such tests for the NESC‚ because certification as a NESC inspector does not exist. That doesn’t mean there are no qualified NESC inspectors. Let me explain. Read more
