2026 National Electrical Code CMP-15 Public Comment Transcript | Article 517.30- Sources of Power
Electrical transfer equipment refers to devices and systems used to transfer electrical power from one source to another, ensuring a continuous and reliable power supply. This equipment is essential in various applications, including residential, commercial, and industrial settings.
Some common types of electrical transfer equipment include:
These devices are crucial in maintaining the stability and reliability of power systems, especially in environments where power continuity is critical, such as hospitals, data centers, and industrial facilities.
FREE ACCESS: NATIONAL ELECTRICAL CODE
The National Electrical Code covers Uninterruptible Power Supplies primarily in Article 480, titled “Storage Batteries,” and Article 700, titled “Emergency Systems.”
Here are the relevant sections:
For specific details, refer to the current edition of the NEC as it contains the exact language and requirements for compliance.
UL 1008 Standard for Safety for Transfer Switch Equipment is principally a product standard and has no direct competitor standard that matches its scope and adoption. Other standards or certifications may overlap in specific contexts:

The MIL-SPEC catalog and its evolution have had a significant impact on various industries beyond the military sector. Many civilian industries have adopted military standards as a benchmark for quality, reliability, and compatibility in their products and processes.
World War II Era:
The MIL-SPEC system traces its roots back to the World War II era when the U.S. military faced challenges in coordinating manufacturing efforts across multiple suppliers. To address these challenges, the military began developing specifications and standards that detailed the requirements for various equipment and materials, including dimensions, materials, performance criteria, and testing procedures.
Post-World War II:
After World War II, the MIL-SPEC catalog expanded significantly to cover a wide range of military equipment, ranging from electronics and aircraft components to clothing and food supplies. The standards were continuously updated and revised based on technological advancements, lessons learned, and evolving military needs.
Evolution into MIL-STD:
In the 1950s and 1960s, the MIL-SPEC system evolved into the Military Standard (MIL-STD) system to provide even more comprehensive and detailed specifications. MIL-STD documents incorporated a broader scope of requirements, including design criteria, quality control processes, and test methodologies. The MIL-STD system aimed to ensure consistent design and manufacturing practices across contractors and suppliers.
MIL-STD Transition to Commercial Standards:
Over time, the reliance on MIL-STDs started to decline, and there was a shift towards adopting commercial standards whenever possible. This transition allowed the military to benefit from the advancements and cost efficiencies of commercial technologies. However, certain critical military-specific standards, such as those related to security and specialized equipment, continued to be maintained within the MIL-STD framework.
DoD’s Transition to Performance-Based Specifications:
In recent years, the DoD has been moving away from prescriptive specifications (MIL-STDs) towards performance-based specifications. Performance-based specifications focus on defining the desired outcomes and performance requirements while allowing contractors greater flexibility in meeting those requirements. This approach encourages innovation, cost-effectiveness, and broader industry participation in military contracts.

Today we dwell on titles that inform management of the education industry in the United States specifically; but also more generally in global markets where the education industry is classified as a Producer and a User of human resources. It is an enormous domain; likely the largest.

We find relatively few public consultations presented by accredited standards developers in the human resource domain; surprising because human resources are the largest cost center in nearly every industry. Alas, manufacturers, insurance and conformance companies remain the strongest voices; the “wicked problem” we describe in our ABOUT.
Even before the circumstances of the pandemic inspired a revisit of large government politics and cultural mashing in education communities in the United States we could hear the first footfalls of disruption when ANSI catalyzed the creation of a related entity in 2014, described in the link below:
WORKCRED: Connecting credential, competencies, careers, customers
The proper business of the education industry overall — and the ~$500 billion facility segment we track — is preparing the workforce everywhere to contribute to national economic priorities. There is a strong cultural component in the human resource domain — i.e. branding — the topic of another post. For now, we simply suggest that much of the economic activity of education communities is devoted to building a cohort (or guild) that creates an emotional bond that hastens learning and a continual desire to self-educate to remain part of the cohort.
At the moment, the WORKCRED program at this point in its development, appears to provides guidance to conformance and compliance organizations among its members. The user-interest in the education facility industry, at least dependent on a skilled workforce as any economic sector, and welcomed to participate. We identify the initiative here and will keep a weather-eye out for commenting opportunities on draft consensus products emerging from it. The link below should provide a more detailed overview of the program until a “commentable consensus product” suitable for incorporation by reference into legislation is released.

Of course, there will be cultural competition among the guardians of the cohort.
Organizations with their own credentialing enterprises for skilled trades, ICT, software engineering, etc. — are encouraged to communicate directly with the WORKCRED staff (CLICK HERE).

Samuel Barber’s Adagio for Strings (1936) is a slow, lyrical orchestral piece adapted from the second movement of his String Quartet, Op. 11. Premiering in 1938 under Arturo Toscanini with the NBC Symphony Orchestra, it features a simple, ascending melodic line that builds through intensifying harmonies and dynamics, peaking in anguished dissonance before resolving into quiet resignation.
In Western classical music, the “Adagio” represents the pinnacle of 20th-century American romanticism amid modernism’s rise. Barber rejected avant-garde experimentation (e.g., serialism by Schoenberg), drawing instead from Bach, Brahms, and Sibelius for tonal accessibility and emotional directness.
