Electrical Industry Articles and Stories

Whole-home surge protection has become a much bigger issue for residential electrical contractors in the last year as local authorities have begun adopting the 2020 edition of the National Electrical Code (NEC).

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.

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.
