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. 

Maintenance and renovation services don’t get much more complex, challenging or fluid than in data centers. As cloud-based computing pervades, data centers are becoming more plentiful, the data they collect and manage is growing, and security needs are becoming more critical.


All electrical contracting companies—especially those involved in low-voltage work—rely on technology. Sprig Electric considers technology to be one of its most important competitive advantages, along with efficiency and personal service.
