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.

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.
