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. 

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.

Planning


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.
