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. 

Are your low-voltage and security customers concerned over “hanging” security cameras on the enterprise network and opening it to potential vulnerabilities? Or are they looking at protecting other parts of their commercial facility that may be housing data and other privileged information? reported in October 2014 that the United States has more electrical grid blackouts than any other developed nation and that, according to the U.S. Department of Energy (DOE), demand for electricity has outpaced transmission rates by 25 percent every year since 1982.

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.

Ethernet Evolves at Lightning Speed

Ethernet...good old Ethernet. It seems as if this type of LAN technology has been around virtually forever. It also seems as if Ethernet will continue to be the driving force behind system networking, especially since this technology continually changes with time.

Tune into Wireless

We’ve come to know it and love it: the wonderful world of wireless. Otherwise known as radio frequency transmission, wireless has gone mainstream, with hands-free and remote capabilities a way of life. If you think electrical contracting has nothing to do with wireless, you’re wrong.

Power Bridging Strategies

For years now, the increasing demand for backup power has been a major issue for both consumers and electricians because voltage surges can bring an entire home or office to a standstill.

Resisting Change

Since the 1980s, the National Fire Protection Association’s fire alarm standards have required the notification appliance (speaker) circuits used in high-rise building Emergency Voice/Alarm Communications systems to “survive” during a fire.

New Multimode Fiber Spec Approved

Previously, I informed you about ongoing activity concerning 10 Gbps Ethernet and a new multimode fiber. In March 2002, TIA approved the standard for this new multimode fiber and probably by the time this article is published, IEEE will have approved the 10 Gbps Ethernet specifications.

Why is Bandwidth Finite?

When fiber was introduced,its enormous bandwidth and extremely low attenuation made it the No. 1 choice to replace copper in long-distance telephone networks. Once the telcos switched from multimode to single-mode fiber in 1984, they found almost boundless bandwidth.
