Electrical Industry Articles and Stories

Electrical contracting is, by its nature, a bespoke profession – that is, every installation features its own unique design quirks requiring customization. At the same time, though, contractors also now are often dealing with the need to do more with fewer workers. As a result, prefabrication is becoming a bigger part of many companies’ operations.

With winter now in force, the snow shovel and bag of ice-melting pellets have returned like migrating songbirds to their seasonal perches on my back deck. I live in a part of southeast New England that doesn’t get a lot of snow, on average, but is also quite capable of getting buried if a nor’easter follows just the right track up the coast.

Earlier this year at the Light + Building 2018 trade show in Frankfurt, Germany, Philips Lighting announced a string of new initiatives aimed at the transition to more LED lamps as well as the inclusion of LEDs into the “Internet of Things” (IoT) in homes and buildings worldwide.

First the company announced IoT platform called Interact, designed to handle data collected from connected light points, sensors, devices and systems.

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.
