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. 

Rampant technology refinement and innovation are redefining security. More technologies help ensure mobile accessibility.

One byproduct of the renewable economy has been the growth of microgrids, as large institutions and communities look for new ways to accommodate distributed generation and utilities take measures to increase grid reliability.

Among tech companies, Tesla has always done things in a big way. Recently, the Palo Alto, Calif.-based manufacturer of luxury electrical vehicles added to its list of outsized endeavors when it announced a major battery storage project for electric utility Southern California Edison (SCE).

The quote “The more I learn, the more I realize how much I don’t know,” is popularly attributed to Albert Einstein.
