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. 

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.

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.

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

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.

From David Letterman to the FBI to Billboard magazine, the “Top 10” can be applied to just about any category, including power quality phenomena. Although it is a highly subjective process, there is some merit in being more than just familiar with them.

Forecast Is A Tool, Not A Prophecy

Each year, we receive construction forecasts that we presumably use to determine what to expect for the promise of work during the coming year. Regardless of what these reports say, the question remains: How do you approach your own construction or work forecast?

Last month, I discussed the evolution of PC networks to Ethernet over twisted-pair cables. Toward the end of the 1980s, the IEEE created a new standard for Ethernet called 10Base-T, which means 10 megabits per second (Mbps), baseband (AM, not FM) over unshielded twisted-pair (UTP) copper cable.
