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. 

Demand for wiring and cabling is expected to grow in the months and years ahead. Low-voltage applications for light-emitting diode (LED) technology and fiber optic cabling within the power-generation and telecommunications industries will help drive this market.

The 93XC OTDR is part of the Greenlee Communications family of fiber equipment.

With the increasing use of fiber optic cable in structured wiring, many electricians experienced in low-voltage copper work are extending their skills to include fiber. Working with fiber requires training and the right tools and testers to correctly install and maintain fiber optic cable.


At a recent meeting, a comment was made that many power quality (PQ) monitor users purchase equipment that is just “good enough.” PQ monitors can be a significant capital equipment purchase for some companies, particularly smaller electrical contracting firms.

Since its humble beginnings in 1981, Metropolitan Electrical Construction in San Francisco has grown to a staff of almost 300 (250 field staff and 40 office employees) by ensuring that it can offer a number of competitive advantages to the marketplace.

The Passing Of Our Industry's Father

This month, we honor perhaps the most notable person in the history of the power quality (PQ) industry, often called the father of PQ monitoring: Abraham I. Dranetz. Some of us knew him as Abe, and others knew him as Mr. Dranetz.

Where Will You Be In 10 Years?

“Where will you be 10 years from now if you keep on going the way you are going?” Napoleon Hill, one of the great writers on success, famously asked this question. When you apply it to the fire alarm and signaling business, it should give you pause.

Got IP Cameras?

For electrical contractors installing video surveillance and networked Internet protocol (IP) cameras, now is a great time to think outside of the proverbial box and look beyond the typical security applications of viewing and recording images of people, places and things.

My System is Survivable (I Think)

Designers, contractors and authorities having jurisdiction often misunderstand the term “survivable.” They presume it means the installer has chosen to use either a Class A wiring scheme or has placed the circuits in metal raceway.
