Electrical Industry Articles and Stories

It truly amazes me how LEDs have transformed the lighting industry in just a decade. In 2012, manufacturers introduced the first bulbs to match the output of a standard 60W incandescent. They weren’t dimmable and could cost $25 or more. Fast forward to 2023, and LEDs now dominate the lighting market, and inexpensive replacement lamps can cost less than $5 and last 10-20 years.

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.

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.

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.
