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. 

Some cabling industry stakeholders predict the imminent death of copper cabling, while others disagree. However, most agree that fiber optical networks are taking a large bite out of the new network market.


This month, we honor perhaps the most notable person in the history of the power quality (PQ) industry, often called the father of PQ monitoring: Abraham I. Dranetz. Some of us knew him as Abe, and others knew him as Mr. Dranetz.

“Where will you be 10 years from now if you keep on going the way you are going?” Napoleon Hill, one of the great writers on success, famously asked this question. When you apply it to the fire alarm and signaling business, it should give you pause.


For electrical contractors installing video surveillance and networked Internet protocol (IP) cameras, now is a great time to think outside of the proverbial box and look beyond the typical security applications of viewing and recording images of people, places and things.
