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. 

Last month, we discussed “dark fiber” and how most outside plant installations include more fibers than are needed at the time of installation. Later, those fibers will be used for expanding service capacity or leased out to provide income.

Our Houses—or, at least, the houses of the tech-savviest among us—are getting closer to running autonomously. Now, it’s not just that you can open your garage door or turn on your living room lights from a smartphone app.

Do you have a customer that requires additional access control at specific locations within their facility but no budget for a total rip and replace? Maybe they are concerned with hacking or data compromise.

The categories or labels used to describe the plethora of power quality phenomena that can occur on electrical systems have not changed much in the past decade or two. Measurement methods and acceptable limits for most systems have changed.
