It has been almost three years since the ASHRAE 90.4 Energy Standard for Data Centers was finalized and went into effect in 2016, yet even today, many in the data center industry are not fully aware of its existence or its implications.

When large inductive loads — loads consisting of large motors and/or transformers — are transferred between two live power sources, e.g., a normal source (1) and an emergency source (2), which may not be in synchronism, efforts should be made to eliminate line current transients that occur during this type of switching.

Aging power control and automation systems can carry risk, both in terms of downtime of mission-critical power systems, through reduced availability of replacement components and the knowledge to replace existing devices within.

The Starline® Plug-In Raceway was created to meet the ever-changing power distribution needs of the mission critical environment.
