Electrical Industry Articles and Stories

With the rise of green building, building professionals have become much more familiar with what goes into the products they specify and install. For example, volatile organic chemicals – more frequently know by the acronym VOCs – have largely disappeared from paint, carpet and other building products due to greater awareness of the health problems they can cause.

Lighting automation has bells and whistles, but a lighting contactor is necessary to switch the actual lighting circuits. Properly selecting lighting contactors can save installation and maintenance costs. What are some of the important considerations in addition to the correct voltage and current?

In new construction, sustainable building practices are becoming the norm. But even in existing buildings, simple strategies can be implemented quickly and easily to address inefficiencies, reduce energy use, improve comfort, and enhance productivity in the space.

Some facilities are changing their requirements for motor and appliance installations. This could be due to OSHA Lock-out and Tag-out requirements or NFPA 70E. The change is toward using pin and sleeve devices instead of having a hard-wired installation.

Safety requirements often have the maintenance person checking for the absence of voltage before touching. The rules are quite specific and are enforced by OSHA.

Bonding and grounding are simple concepts, but, unfortunately, they’re also easily confused with each other. Definitions of one term often get wrapped up in the definitions of the other, and, before long, one can begin thinking the words are interchangeable.

“Grounding” refers to the creation of a path from electrical equipment to the earth. It is intended to protect equipment and help prevent fires that might occur due to high voltages resulting from lightning strikes, line surges or unintended contact with higher-voltage lines.

The dependence on quality, reliable data is now more business-critical than ever. Businesses rely on data centers for 24/7 connectivity; to uphold federal codes and regulations; and to ensure resiliency, performance, and more—all so the business can stick to meeting the demands of their own customers. Data centers should also be highly adaptable.
