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.

Fiber Optic Update

Fiber optics, as we all know, has not had a very good time the last couple of years, with the overall market dropping by almost 80 percent (see chart at top right).

Installing a Service Disconnect

Many changes have occurred to the National Electrical Code (NEC) since the first NEC was published on Aug. 31, 1897. Even though the electrical industry was in its infancy, this “first” NEC was remarkably insightful and has withstood the test of time.

IBS: Here Today, Here to Stay
