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. 

Contractors that are still putting estimates together using pencil and paper are not only wasting time and money, but they also are losing business. Contractors who think they can’t afford estimating software are just plain wrong.

Plug loads, according to a pilot study performed by New York-based green technology company ThinkEco Inc., make up the fastest growing end-use of electricity in the commercial sector. As the amount of electricity used by plug loads grows, it becomes increasingly important to manage it.

In attempting to explain to a colleague why we care about negative sequence components, I tried to follow the guidance that Bob Lawrie, another member of the NFPA 70B Electrical Equipment Maintenance committee, offered to me many years ago: never use a formula in an article.

Another year has passed, and we have nothing revolutionary to report about fiber optic technology—no instant-on connectors, dirt-cheap lasers or simple solutions to installation problems.
