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.

Testing for Category 6 Cabling

As you may know, the Telecommunications Industry Association (TIA) has agreed that Level III-qualified testers are to be used when certifying or verifying Category 6 cabling systems (Category 6 cable is a 100-Ohm cable with transmission characteristics specified up to 250 MHz).

The Little Engine that Could

Ask most electrical contractors about the latest cogenerating technology—microturbines—and you’re likely to get silence, or possibly: “micro-what?” This technology, which has only been on the market a few years (Capstone Turbine’s C30 model was introduced in December 1998), may still be relatively u
