Grandfather Provisions
Today at the usual hour we examine a few proposals for the 2028 National Electrical Safety that involve the degree to which merchant utilities should be required to replace system elements with elements meeting a higher standard than the standard to which the system element was originally built.

NESC 2028 Call for Comment
The NESC Subcommittees have specifically requested public comment on ten proposals from affected interests. Today at the usual hour we will discuss them in detail and draft responses to be submitted before the April 9th deadline.
CP6007
CP6008
CP6026
CP6117
CP6292

CP6581
Part 3: Safety Rules for the Installation and Maintenance of Underground Electric Supply and Communication Lines CP6253
Part 5: Safety Rules for the Installation and Maintenance of Electric Generating Stations and Equipment
The new Part 5 was developed to focus on developing and enhancing procedures to safeguard persons during the installation, operation, or maintenance of an electric generating station and their associated equipment. These responsibilities used to be part of Subcommittee 3, which deals with electrical substations. Part 5 is placing particular emphasis on renewable energy, grid storage batteries, and distributed energy resources. The submitted change proposals produce updates to the Code in these areas.
High Voltage Electric Service
Federal Power Act of 1920 Ω Public Utility Holding Company Act of 1935.
IEEE Education & Healthcare Facilities Committee Ω Current Issues and Recent Research
Representative Sample of Merchant Utility Interconnection Requirements for Customers
2023 National Electrical Code Article 490 Bibliography
Ahead of the April close date for comments on the Second Draft of the 2026 revision of the NEC we examine thought trends on the following:
- How does “high voltage” differ among electrotechnology professionals? Signaling and control systems workers have a much lower criteria than a merchant utility lineman than a campus bulk distribution engineer. In other words, “high voltage” is generally understood in practice and essential for worker safety. Labeling counts.
- What is the origin of the apparent “confusion’ about high voltage in the IEEE, IEC, NFPA and TIA electrical safety catalogs? Is the distinction functionally acceptable — i.e. a term of art understood well enough in practice?
- How can the 2026 NEC be improved for engineers, electricians and inspectors? There has been some considerable re-organization of low, medium and high voltage concepts in the 2023. It usually takes at least two NEC revision cycles for workable code to stabilize. Since education communities purchase and distribute higher voltage power on large campuses; how can power purchasing and customer distribution system best practice be improved?

2029 National Electrical Code Panel 3
Brown University Electrical Design Criteria | Information Technology Resources Policy
The University of Michigan has supported the voice of the United States education facility industry since 1993 — the second longest tenure of any voice in the United States. That voice has survived several organizational changes but remains intact and will continue its Safer-Simpler-Lower Cost-Longer Lasting priorities on Code Panel 3 in the 2029 Edition.
Today, during our customary “Open Door” teleconference we will examine the technical concepts under the purview of Code Panel 3; among them:
Article 206 Signaling Circuits
Article 300 General Requirements for Wiring Methods and Materials
Article 335 Instrumentation Tray Cable
Article 590 Temporary Installations
Chapter 7 Large sections of limited energy cabling for signaling and information technology
Chapter 9 Conductor Properties Tables 11A & B, Tables 12A&B
Public Input on the 2029 Edition will be received until April 9, 2026.
Related:
- Since the lifespan of educational buildings make the building core and shell susceptible to multiple changes not typically associated with commercial buildings, additional pathways should be placed in areas where the core and shell components of the facility are likely to re-main for extended periods of time
- It is recommended that all areas of an educational building have wireless coverage unless prohibited
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.

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.
