Power Distribution Units
Today we veer (slightly) from our primary interest in interoperability standards to explore the moment in best practice discovery and promulgation in the hardware supporting the artificial intelligence zietgeist. Use the login credentials at the upper right of our home page.
Carnegie-Mellon: Planning & Design Considerations for Data Centers
University of Kansas Data Center and Server Room Standards
Power Distribution Units (PDUs) are critical in data centers, serving as the backbone for reliable power management. They distribute electricity from the main power source to servers, networking equipment, and other devices, ensuring consistent and stable power delivery.
PDUs offer features like load balancing, surge protection, and remote monitoring, which optimize energy efficiency and prevent outages. By providing multiple outlets and circuit protection, they safeguard expensive equipment from power fluctuations. Advanced PDUs enable real-time data tracking, aiding in capacity planning and fault detection.
Ultimately, PDUs ensure uptime, operational efficiency, and scalability in data centers. We track, and sometimes participate, in the standards setting for these organizations develop the key standards that govern PDU design, safety, efficiency, and interoperability, influencing global manufacturing compliance:
UL (Underwriters Laboratories): Establishes safety standards like UL 60950-1 for IT equipment, ensuring PDUs prevent hazards in high-density environments.
IEC (International Electrotechnical Commission): Develops core electrical standards such as IEC 60950-1 and IEC 62368-1 for low-voltage safety and audio/video/IT equipment, critical for PDU power handling.
ENERGY STAR (U.S. EPA): Sets efficiency benchmarks for PDUs, promoting low-loss designs to minimize data center energy waste (up to 12% savings).Related:

2029 National Electrical Code
Public input on the 2029 Revision will be received until April 9th. Over the next weeks and months — typically meeting twice a day every Tuesday — we will pull forward our previous proposals and draft original proposals relevant to the education and healthcare electrotechnical infrastructure of educational settlements. Link to Proposed Reorganization.

Mike was part of the National Electrical Code Quarter Century Club but was at another conference and not able to receive the award at the June conference. University of Michigan support began in 1993. IEEE support began in 2014.

Current Issues and Recent Research
Today we examine Second Draft transcripts of the Special Equipment Chapter 6 (CMP-12) and product inspection, testing and certification listings that appear Annex A (CMP-1).
Once every eighteen months we spend a week drilling into the National Electrical Code by submitting new proposals or comments on proposed revisions. Today we review the actions taken by the technical committees on the First Draft. Responses to committee actions will be received until August 26th.
