FREE ACCESS: 2025 Standard for Emergency and Standby Power Systems

Public Input for 2028 Revision Received Until June 4, 2025

Academy of Art University | San Francisco County

Elevators rely on electricity to function, and when there’s a power outage, the main source of power is disrupted. Modern elevators often have backup power systems, such as generators or battery packs, to lower the cab to the nearest floor and open the doors, but these systems may not work optimally, or be connected to all elevators or may not exist in older or less well-maintained buildings.

Today we start with getting the source of power right; leaving complicating factors such as alarms, reset and restart sequences.   NFPA 110 is the parent standard which references NFPA 70.

Alumni Memorial Hall was built as a war memorial and multi-purpose alumni building — not originally as an art museum; though it became — and still is — a gathering point for alumni who donated their collections to the University.  Its inspiration originated in 1864 shortly after the Civil War, to honor University of Michigan students, faculty, and alumni who died in that conflict and all conflicts thereafter.

Today we review a draft of an article that covers, in our view, an obvious oversight in the 2026 National Electrical Code.  It is an expansion of a proposal already submitted to the National Electrical Code Technical Correlating Committee and will support challenges to its adoption into the 2029 NEC revision.  Use the login credentials at the upper right of our home page.


Restore the NESC to the Front End of the NEC

Michael A. Anthony | Glenn T. Keates 

Abstract. It may seem like a small thing — to restore the cross-reference to the IEEE National Electrical Safety Code (NESC) at the front end of the NFPA National Electrical Code (NEC) where it used to be — but it is not. This paper explains why restoration of the NEC’s peer document is necessary in the 2029 Edition of the NEC, now under development.

The reasons are both technical and cultural, touching on a minefield of sensitivities about safety, sustainability, and economic development associated with the data center (artificial intelligence) zeitgeist. 

Customer owned interactive sources are not new.  Customer-owned load-side electric services at transmission voltages for private developers and university-adjacent hyperscale installations present consideration are new.[x] 

The NESC, in contrast, maintains a clear “handshake” reference to the NEC in its Scope statement (Section 011). This paper argues for the restoration of a prominent NESC cross-reference in NEC Article 90.2(A)(2) for the 2029 edition. The proposal (Public Input No. 3687-NFPA 70-2026) has already been submitted to NFPA Technical Committee CMP-1.

The first movement of the 1931 “Grand Canyon Suite is a tone poem about dawn breaking over the Grand Canyon. It builds slowly through layered, ascending sonorities and expanding textures, mirroring the sun’s creeping rays.

It swells to full-orchestral climax of brass, capturing the canyon’s majestic reveal. The gentle ascent uses impressionistic colors rather than strong melodies, creating a cinematic sense of awe.  The melodies are original.

The relative thinness of most Asian classical music repertoires helps explain why East Asian students so often excel in the Western tradition. Western classical music presents an immense, densely notated canon—centuries of works across every genre, style period, and technical demand—that requires years of systematic absorption. By contrast, the core repertoires of Chinese, Japanese, and Korean court and literati traditions are far smaller in volume and more limited in formal complexity. They rely heavily on oral transmission, short fixed pieces, or improvisation within narrow modal frameworks rather than the cumulative weight of thousands of fully notated, stylistically differentiated scores.

This comparative sparsity leaves Asian students with fewer deeply internalized musical habits, finger patterns, or stylistic reflexes competing for neural and muscular real estate. When they begin serious Western training, their ears and hands encounter less interference from prior classical conditioning. They can therefore allocate nearly all practice time and cognitive resources to mastering the specific demands of Western notation, equal temperament, functional harmony, large-scale form, and historically informed interpretation—without simultaneously maintaining fluency in a rival dense canon. The result is accelerated technical acquisition and a clearer channel for the intense, focused discipline that Western conservatory training rewards.

In other words, no one likes Asian classical music as much as Western classical music — even Asians — and this explains why they outperform Founding Stock American students in most classical orchestras.   Founding Stock Americans are drawn to other American musical traditions.
