May/June 2002
May is Electrical Safety Month. During this time, many industry professionals and organizations try to focus on the safety aspect of the industry. From enhanced electrical safety writings to seminar offerings, it seems as though students of the Code at all levels contribute in some form or fashion. Electrical safety is no accident. Safe electrical [...]
The objective of this article is to provide IAEI members information on the changing scene of conformity assessment resulting from the effects of globalization of trade. It offers the reader a snapshot of the driving forces in the business environment, the important elements of product compliance, the various levels of activities involved in the conformity [...]
“Beauty is only skin deep,” could not be truer than with electrical equipment. Under that pretty cover or inside that box could be a dangerous condition waiting to explode. Even after the cover is opened a potential problem may not be easily revealed. That first view may reveal the existence of some problems; however, only [...]
The Laws. In many jurisdictions, state and local laws require all electrical equipment to be certified by an approved independent third-party testing laboratory.

Publications include laws, regulations, codes, standards, and recommended practices. Organizations that are essential to electrical safety include standards-developing organizations, electrical installation companies, electric utilities, code enforcement [...]
The 2002 National Electrical Code (NEC) has an added notation that can be confusing. The notion is a fine print note (FPN) to 240.85 of the NEC that reads, “Proper application of molded-case circuit breakers on 3-phase systems, other than solidly grounded WYE, particularly on corner-grounded delta systems, considers the individual pole interrupting capability.” A [...]
In the last IAEI News (March/April 2002), I shared with you the details of the new extreme wind loading requirements of the 2002 National Electrical Safety Code (NESC). For structures sixty feet tall and shorter, the extreme wind loading only applies to the structure. For structures taller than sixty feet, the extreme wind loading applies [...]
To accept or not to accept, that is the question authorities having jurisdiction (AHJs) face on a daily basis. They encounter products with no certification markings, marks from other countries and from a host of testing laboratories. How do AHJs know which mark or service provides compliance with the NEC?
Significant number of electricians are being seriously burned and often killed from an accidental electrical flash while working equipment “hot.” Most of these serious accidents can be eliminated or significantly reduced if the electricians wear the proper type of protective clothing. In a previous IAEI article, I discussed the need for better integration of the [...]
More than 100 million people in approximately 90 countries world wide enjoy the sport of bowling. Bowling has a long and intriguing history tracing its ancestry back to the Egyptians around 3200 BC. In the early 1950s, one of the first automatic pinsetter machines was introduced into bowling alleys. Fifty years ago, this machine was [...]
