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.

Secrets Of Anaerobic Adhesives

I suspect that the idea of employing anaerobic adhesives for fiber optics came from someone using Krazy Glue or the two-part adhesive made to fix a car’s rearview mirror after it fell off in the hot summer sun.

Coming To A PV Panel Near You

In solar installations, ranging from rooftop panels and larger community- and utility-scale arrays, photovoltaics (PVs) are becoming increasingly important to our energy supply.

Damaged dog-fence power source
It Does Strike Again, And Again

Lightning is the biggest cause of damage and destruction of electrical and electronic equipment in industrial facilities, commercial buildings and homes, as stated in the 2008 report by the U.S. National Lightning Safety Institute.

The Total Package

Historically, security system installations have only mandated acceptance testing as the last requirement for a project to be deemed completed.

The Electrical Dipstick

Energy costs and potential energy shortages are increasingly driving commercial building and industrial facility owners to find ways to use less energy for the same level of activity.

Automation Expectation

Residential end-user expectation is fueling automation expansion not only in the homes of the wealthy but also in middle class developments where residents expect to be able to manage the operation of their homes with their cell phone or tablet.

Giving The Homeowner Control

The advertisements bombard us constantly. On television, on websites, in your inbox, all with the same message: everyone else is using technology that integrates security systems with home automation and enables remote control of the whole house with smart devices. Why aren’t you doing this too?
