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. 

A variety of carts and reel carriers are available to hold and transport wire reels.

From shipping and arrival of wire supplies through installation, efficiently managing electric wire on the job can be the difference between a profit or loss.


When it comes to the adoption of energy efficiency and renewable power, financing is always a challenge, especially in rural areas. A new partnership between a business group and an environmental advocacy organization takes aim at that challenge.

I know from experience with contractors in the field that, when it comes to mass notification systems (MNS), being required to perform a risk analysis for the MNS ranks just above getting a root canal at the dentist’s office!


With all the talk about advancements in so many categories of building cabling, wireless networks that support in-building communications, resilient mission critical infrastructure, and adding new intelligent amenities into next-generation real estate, how far have we really come in 30 years?
