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.

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.
