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. 

Splicing safety mostly follows the same guidelines installers use when installing any fiber optic cable plant. However, there are some special issues to be aware of.

My January 2015 article, “It’s Just Math,” explained how various parameters used to evaluate power quality (PQ) are derived while avoiding formulas and other mathematical expressions.

Electrical contractors (ECs) are bearing witness to dramatic changes in the physical security industry. Everything is moving to the network. Customers connect to systems and services with smartphone apps.

In my 40-plus years in fire protection, I have learned that electrical contractors (ECs) sell and install the lion’s share of fire alarm systems in medium- to large-size buildings. Most of these contractors also finish the installation, pass the acceptance test and move on to the next project.
