Consulting-Specifying Engineer Top 5 most read articles online, for Dec. 8-14, covered 3-and 4-pole transfer switches, flexible and sustainable electrical systems, data center harmonics, young architects challenging engineers, and energy storage for peak-load shifting. Link to each article below.

1. Choosing between 3-pole and 4-pole transfer switches

The choice between a 3-pole and 4-pole transfer switch depends on whether the emergency power system will be a separately-derived source. 

2. Flexible, sustainable electrical systems

Current building codes and standards allow designers to build flexibility into the electrical system. 

3. Mitigating data center harmonics

Data center managers and information technology (IT) engineers in today's critical facilities are in search of reliable and energy-efficient equipment with low total cost of ownership. But after equipment investments are made, it's important to keep a watchful eye on possible threats to operational efficiency. 

4. Young architects challenge engineers

The newest generation of architects wants to be part of the larger plan. 

5. Implementing energy storage for peak-load shifting

Engineers should offer building owners the ability to reduce energy load by shifting it from peak to off-peak hours. 

The list was developed using CFE Media's web analytics for stories viewed on, December 8-14, for articles published within the last two months.
