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. 

With the new presidential administration coming into the White House, will this be the year of advancing infrastructure? Will there be a diversified trillion dollar infrastructure project to jumpstart the economy as well as fill your schedules and your wallets?

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.
