Consulting-Specifying Engineer's top 5 most read articles online, for August 14-20, covered NFPA 99-2015 changes, MEP Giants, selecting transformers, generator system installation, and arc flash mitigation. Link to each article below.Top 5 Consulting-Specifying Engineer Articles, August 14-20

1. How NFPA 99-2015 changes affect mechanical design

NFPA 99-2015 has a few changes that mechanical engineers should pay close attention to.

2. MEP Giants revenue increases, along with staffing concerns

The 2017 MEP Giants gross revenue increased as compared with last year, likely due to company mergers and larger and more varied projects. MEP/FP design revenue also increased.

3. Selecting and sizing transformers to achieve energy efficiency

Eddy currents are generated from changing magnetic fields. These circulating currents are wasted energy and generate heat at the transformer core. Core losses also can be generated through hysteresis.

4. Paralleling generator systems—part three: installation considerations

When designing generator systems, electrical engineers must ensure that the generators and the building electrical systems that they support are appropriate for the specific application. Whether providing standby power for health care facilities or prime power for processing plants, engineers must make decisions regarding generator sizing, load types, whether generators should be paralleled, fuel storage, switching scenarios, and many other criteria.

5. The basics of arc flash mitigation

Electrical engineers must understand the codes, standards, and design requirements when engineering for arc flash mitigation.

This list was developed using CFE Media's web analytics for stories viewed on www.csemag.com, August 14-20, for articles published within the last two months.
