Systems

 

 

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. 

Once known as demand-side management, the implementation of products and practices designed to modify electricity consumption are proven methods for electricity providers and consumers to control usage.

In 2012, the National Fire Protection Association adopted NFPA 3, Recommended Practice on Commissioning and Integrated Testing of Fire and Life Safety Systems. Since then, it has been split into two separate documents.

Technology is changing so fast these days that we could almost call this a “technology invasion.” Sometimes, it seems the technology and systems needed to accomplish the work changes in the time between one project ending and another project going out to bid.

As with any project, a communications cabling project requires comprehensive management. Project management for cabling or related networks is best understood when broken into five subtopics:
 Planning, Design, Installation, Testing and Operation.
