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.

Regardless of the changes in our federal government this year, there is one thing we know for sure: we have a new NFPA 72 2016, National Fire Alarm and Signaling Code from the National Fire Protection Association. Does that mean we should have started using the new code on Jan. 1?

The proliferation of alternative forms of lighting—for example, LED lamps—has been accelerated by the significantly limited sale of incandescent light lamps. In case you forgot, incandescents failed to meet the efficiency rules of the Energy Independence and Securities Act of 2007.

The application of fiber optics has been growing rapidly.
