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 quote “The more I learn, the more I realize how much I don’t know,” is popularly attributed to Albert Einstein.

Commercial building energy codes impose design standards for nonresidential buildings’ energy efficiency. Many states have implemented an energy code to regulate building design.


For many of us, these are technologically challenging times. Just when I think I have mastered the latest smartphone, it changes. Prepare yourself, because, just like mobile devices, the codes and standards are morphing in ways you might not expect.


When manufacturers are asked what is the biggest problem with installing of fiber optic components and systems, they invariably say “testing.” Practically everything they do depends on testing. During development, engineering and manufacturing in their labs, they test product performance.
