Electrical Industry Articles and Stories

There’s no getting around it. A lot of people spent a lot more time in their homes the past few years. And while some of it was by choice, not all of it was.

I retired from electrical work and work my copywriting business totally from home now.

That was a choice.

Flashlights used to be just, well, flashlights – handy tools for bringing a little illumination to whatever task was at hand. They also could be a little undependable in the old days. Battery strength was always a question, especially if they hadn’t been used in a while.

Looking through a manufacturer’s online enclosure catalog recently, I came across a term I hadn’t heard before. Now, I’m not a contractor, so I likely haven’t seen as many of these listings as you might have. But I am a journalist who has covered the construction industry for several decades, and the term “mild steel” stuck out to me when it showed up as a material option for the maker’s broad range of enclosure offerings.

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.

Switchboards are critical to the dependability of any electrical power installation because they represent that pivotal point at which incoming power supply is divided into separate circuits, controlled and protected by fuses and switchgear, metered, and then divided into a number of functional units for its given applications. In general, switchboards distribute power to transformers, panelboards, control equipment, and to system loads.

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.
