Systems

 

 

Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do. The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more. 

The predictions have arrived! Analysts expect the first quarter of 2015 to show a rapid rise in commercial construction. Obviously, this is good news on almost all fronts.

One of my responsibilities over the years has been to field questions from our members and authorities having jurisdiction (AHJs) to help them find and understand code requirements. I have benefitted from the process as well.

A limited number of low-voltage contractors specialize in the installation of sprinkler systems power and controls. For them, it provides a regular source of revenue that most contractors have bypassed.

In this third part of my series on the most common power quality phenomena, I group several IEEE 1159 categories together under the general description of “distortion.” Though one might argue that all power quality phenomena result in distortions of the voltage sine wave, these are the more steady-s
