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. 

Workflow-management tools are designed to orchestrate everyday business processes. For example, a contractor may implement a process for submitting, reviewing and approving expense reports.

While the electric power industry rapidly changes, utilities and building owners will need to accurately model the engineering and economic operations of the power system to make informed decisions, so they require sophisticated modeling-software tools.


Power is everything. Consumers demand connectivity to home, business, people and places 24 hours a day. In this uber-integrated information society, staying in touch through Wi-Fi, Ethernet, cellular and other networks is the expectation.


Design/build means different things to different people. Regardless, you should know that it places more responsibility on your shoulders as the electrical professional. It means you need to stay abreast of the codes that affect your installations.
