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. 

All of those millions of miles of dark fiber are primarily expected to deliver broadband connections. The Internet continues to grow unabated, and bandwidth must be expanded to accommodate that growth. 

Sometimes called the third wave of the Internet, the Internet of Things (IoT) is the next technology megatrend.

There is an old saying that liars figure and figures lie, which implies that the truth can be a challenge to discern from both people and data. At a recent standards-making conference, I encountered some examples of this concept that seemed worth sharing.

For electrical contractors with a low-voltage or security division—or for any company involved in physical security and surveillance—keeping pace with new technology is one of the greatest challenges.

Contracting By Proxy

McClure Electric, San Francisco, has been in business since 1966, but it wasn’t until the mid-1990s that it got involved in low-voltage work.

Stick 'em Up Using Epoxy

I am always amused when I hear, “No one uses heat-cured epoxy connectors anymore.” In fact, about 95 percent of all connectors, including every factory-made patchcord, uses heat-cured epoxy for its ease of use, low cost and high reliability.

It Just Makes Cents

NFPA 70B, Recommended Practice for Electrical Equipment Maintenance, has championed the importance of an electrical preventative maintenance (EPM) program for years.

Residential Properties

Residential home fire alarm protection methods can be broken down into two distinct applications: stand-alone detection devices, known as smoke alarms or carbon monoxide (CO) alarms, and combination fire alarm and detection systems that employ smoke detectors and CO detectors connected to a resident

Maintaining Smoke Compartments

When we install fire protection
in a building, we are focused on active protection systems such as fire alarms, fire sprinklers, clean agents or smoke control.

Cleaning Fibers Is Crucial

In several recent columns, I discussed the process of fiber optic terminations. I examined each step in detail and shared some of the things I have learned from experience and teaching students. As they say, one learns from one’s mistakes.

Taming The Energy Hogs: Data Centers

Data centers are energy hogs. They can consume up to 100 times more energy than a standard office building, according to the Department of Energy’s (DOE’s) Office of Energy Efficiency and Renewable Energy (EERE).
