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. 

As I have described in the previous few columns, splicing fibers is fairly easy. If the installer cleans and cleaves the fibers properly, the machine does the rest. However, the installer’s job is not over at that point.
