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. 

All of that dark fiber we have been discussing the last few months is getting used for some fast-growing applications, and the fastest may be connecting cell towers. Cell phones have evolved into mobile data devices. Smartphones and tablets consume vast amounts of data.

A hot summer’s evening usually begets long lines at the local ice cream shop. Recently, at one such shop, the line grew extra long when the cash registers and credit card machines mysteriously powered off and on.

Historically, if a problem occurs with a traditional string power inverter that links several solar panels together in series, or even simple shade, that issue can bring down an entire solar photovoltaic (PV) array.

As government tax credits and utility rebates and incentives dry up, energy-efficiency improvements have evolved beyond the low-hanging fruit of fixture replacement at low cost.
