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. 

As projects become more complex, electrical contractors need high-tech management methods to ensure more efficient results. Here are just a few examples to help you get headed in the right direction. 5pm

The dark fiber providers that most people are familiar with are private companies that were started to offer fiber connectivity for a profit. Today, there is a major movement toward building fiber networks as a public-private partnership.

When considering power quality disturbances or the quality of the electrical supply, phenomena such as rms variations (sags, swells and interruptions), harmonics, unbalance and flicker usually come to mind.

Data center infrastructure management (DCIM) software enables data center operators to manage assets and changes, plan capacity, and monitor power, environment and energy usage.

Bigger Data

The evolution of data center technology is outpacing changes in nearly every kind of commercial building, making the data center installation and service market lucrative. However, it comes with plenty of challenges.

Lighting Up Dark Fiber

Last month, we looked at how dark fiber is tested to determine its capability of supporting newer, faster transmission networks. Once dark fiber has been tested and its usability confirmed, communications systems can be connected.

Alleviating The Fear Of Fiber

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.

The Passing Of Our Industry's Father

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 In 10 Years?

“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.

Got IP Cameras?

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.

My System is Survivable (I Think)

Designers, contractors and authorities having jurisdiction often misunderstand the term “survivable.” They presume it means the installer has chosen to use either a Class A wiring scheme or has placed the circuits in metal raceway.
