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. 

We all use tools and test equipment to perform our daily work. Sometimes, it’s a basic hand tool, such as a screwdriver. Sometimes, it’s more sophisticated.

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
