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. 

In several recent columns, I discussed the process of fiber optic terminations. I examined each step in detail and shared some of the things I have learned from experience and teaching students. As they say, one learns from one’s mistakes.


Data centers are energy hogs. They can consume up to 100 times more energy than a standard office building, according to the Department of Energy’s (DOE’s) Office of Energy Efficiency and Renewable Energy (EERE).

Dranetz Model 606 was introduced in 1975.

The importance of monitoring the quality of the electrical supply has increased with the ongoing push to boost uptime, productivity and profits. When carrying out business 24/7, having a process or operational interruption can negatively affect of the bottom line.

Invented in the 1980s at Eastman Kodak, organic light-emitting diodes (OLEDs) are composed of a layer of organic material situated between an anode and a cathode and deposited on a substrate.

I guess the honest answer to the above is, “We’re working on it.” Most manufacturers have products (cable, jacks, patch cords, and test equipment) out in the marketplace promoted in one fashion or another as Category 6 compliant.
