Short Circuit Current Ratings

Overcurrent protective device interrupting ratings (IR) and equipment short-circuit current ratings (SCCR) are key considerations for the safety of commercial and industrial electrical systems. Inadequate overcurrent protective device IR or equipment SCCR can create a serious safety hazard. The National Electrical Code (NEC®) and Occupational Safety and Health Administration (OSHA) have requirements around these important ratings and have resulted in changes to equipment designs and specifications.


Why Bonding?

I’ve been in the electrical trade for 33 years. I’ve been an apprentice, journeyman, master, electrical inspector, and now the Training Director at the IEC Gulf Coast Chapter in Houston, Texas.

One common denominator throughout the years is the misinterpretation, misapplication, or the complete disregard of Article 250 and proper bonding.


Save Time and Energy with Wireless Lighting Control Retrofits

To reduce energy use in existing buildings, few systems can have the same impact as lighting and lighting control retrofits. According to the U.S. Department of Energy, buildings consume 39 percent of the total U.S. primary energy. In commercial buildings, 28 percent of the energy use is devoted to lighting, which makes lighting an obvious target for gaining energy efficiencies.


Do You Understand Your Overhead - And How to Recover These Costs?

What's in your "overhead" - and what isn't? This basic question can be answered a number of ways. Here's a look at what belongs in the overhead category and how you might think about it.


Electrical Contractors' Unique Stake in the National Electrical Safety Code (NESC)

Regardless of what part of the utility industry that they are in, electrical
contractors are directly impacted by the National Electrical Safety Code®
(NESC®) and its ongoing evolution. The code—from its work practices
for employees, including the responsibilities of electrical contractors
in relation to those of employers and host employers, to its detailed
guidance on grounding, clearance issues, construction strength, and loading—in
one way or another bears heavily on the daily work of elecrical contractors.
Now is the time for electrical contractors and any other concerned party to help
shape the next, 2017 edition of the NESC. From September 1, 2014, to May 1, 2015,
runs a period in which anyone can electronically submit comments on the “Preprint”
of proposed changes to the current edition of the code. Ensuring that the NESC
remains realistic, practical, and useful and in alignment with new developments,
technologies, and challenges in the industry relies on stakeholders across the
utility industry seizing their opportunity to provide their opinions and insights.
It is a particularly worthwhile endeavor for electrical contractors because no one has a
more valuable perspective or has more at stake in the NESC than those workers with
boots on the ground. The ongoing open commentary period is your opportunity to
chime in on whether you agree or disagree with the proposed NESC changes and why.
