Chapter 9 Tables
Top 10 Issues
Issue
Summary
1. Consistency of Code Language
Standardize terminology throughout the NEC by eliminating inconsistent wording, duplicate phrases, and varying expressions that describe the same technical concepts.
2. Compliance with the NEC Style Manual
Many proposals seek removal of redundant requirements already addressed elsewhere in the Code, resulting in a cleaner, more concise document.
3. Restoring Lost Requirements
Numerous submitters argue that important technical provisions disappeared during recent article reorganizations and should be restored.
4. Article Organization
Improve article formatting, numbering, and overall structure to make the NEC easier to navigate and maintain.
5. Emerging Technologies
Expand the Code to better accommodate fault-managed power, battery energy storage, portable power systems, EV-based power sources, hydrogen technologies, and new circuit classifications.
6. Installation Clarification
Clarify requirements for raceways, wet locations, roof decks, cable trays, conductor spacing, barriers, and other installation practices.
7. Installer Safety & Reliability
Enhance electrical safety through improved wiring practices, better physical protection, stronger cable support requirements, and fewer failure points.
8. Definition Ownership
Assign definitions to the Code-Making Panels having primary technical expertise to improve long-term consistency and maintenance.
9. Coordination with Other Standards
Improve harmonization between the NEC and companion standards such as UL, ANSI, NFPA 79, and hazardous-location requirements.
10. Reducing Complexity
A recurring objective is to simplify the NEC by reducing duplication, improving readability, and making the Code easier for installers, inspectors, designers, trainers, and licensing authorities to use.
The Public Inputs demonstrate a broad desire to make the National Electrical Code more consistent, technically complete, better coordinated with related standards, and easier to understand without compromising electrical safety. Many proposals emphasize restoring requirements inadvertently lost during recent reorganizations while preparing the Code to accommodate rapidly emerging electrical technologies.
Mike recommends these issues as priority for the Joint IEEE IAS/PES committee
N.B. Public Input No. 2633-NFPA 70-2026 [ Global Input ] PDF Page 6, regarding re-organization of the NEC into below 1000 V and above 1000 V.
Noteworthy proposal concepts:
Cable trays interfering with HVAC ductwork and fire sprinkler lines. Parallel cable tray feasibility
Difficulty accessing lighting fixtures and fire alarm components for maintenance.
Potential violation of plenum clearance and airflow requirements. Some cable trays in plenums reportedly contain non-plenum-rated cables, which is a fire code violation.
Document flags this as a high-priority remediation item before any LED lighting retrofit proceeds.
Existing security wiring (CCTV, access control, intrusion detection) is a mix of old analog coax and early Cat 5 cables.
Many runs exceed recommended length for reliable video transmission. Frequent signal degradation and reliability complaints.
Security cables are sharing overcrowded cable trays with power-limited lighting control wires and fire alarm cabling.
Risk of electromagnetic interference (EMI) noted due to proximity to higher-voltage lines.
Plenum space constraints make it difficult to add new IP-based security cameras without major reorganization.
Current security wiring cannot support newer high-resolution IP cameras or PoE+ powered devices.
Several editorial proposals by Mike Holt. (He’s generally correct on clarity improvements that he needs for educational purposes)
Ω
For discussion next meeting, when we march through all proposals of interest to IEEE:
When electricians work in ceiling plenums above hallways while students pass below, several serious hazards emerge. Tools, screws, cable scraps, or ceiling tiles can fall, causing head injuries or slips. Disturbed dust, fiberglass, or potential asbestos particles may rain down, creating respiratory risks.
Live electrical work on lighting or cable trays raises shock/fire dangers if a fault occurs or debris shorts circuits. Open plenums can compromise fire-rated barriers, allowing smoke or flames to spread rapidly in an emergency.
Noise and visual distractions increase trip hazards for students. Without full barricades, lockout/tagout, and proper fall protection, these overhead activities expose young people to preventable injury. Scheduling work after hours or using full corridor closures is essential.
Power-limited (Class 2) cabling operates at low voltage (<60V DC) with current/power caps (~100VA), dramatically reducing shock and fire risks. Installation is simpler and cheaper—no conduit or heavy mechanical protection needed in many cases, allowing flexible routing. LEDs run cooler and more efficiently with remote drivers, improving lifespan and energy savings. Easier maintenance and safer for retrofits.
Severe distance and power limits due to voltage drop and 100W/5A caps require multiple drivers or shorter runs. Higher upfront costs for specialized power supplies. Potential reliability issues from more connection points. Less suitable for high-power or long-distance applications compared to line-voltage wiring.
Public Inputs Relevant to School and College Facilities
Campus Facility
Relevant Issue
Why It Matters
Student Health Centers, Medical Schools & Campus Hospitals
Improved protection of underground feeders, raceways, and wiring methods, together with replacement of conductors damaged by water, fire, corrosion, or severe physical impact.
Enhances electrical reliability for healthcare occupancies where continuous operation is essential.
Athletic Stadiums & Arenas
Improved protection of underground services, direct-buried conductors, warning ribbons, and raceways.
Supports reliable electrical service for stadium lighting, scoreboards, concessions, and outdoor utility infrastructure.
Temporary Athletic & Campus Events
Recognition of modern portable power sources, including battery energy storage systems and portable fuel cells, in addition to traditional generators.
Useful for commencement ceremonies, concerts, athletic tournaments, festivals, and temporary event power.
Research Laboratories
Expanded wiring methods for hazardous (classified) locations, including ITC-HL cable installations.
May affect university research laboratories, pilot plants, engineering facilities, and chemical research buildings.
Residence Halls & Classroom Buildings
Improved protection against concealed wiring damage caused by nails, screws, and furring strips during construction and renovation.
Helps reduce wiring damage during frequent campus remodeling and maintenance projects.
Campus Utility Infrastructure
Clarifications involving direct boring, underground raceways, service feeders, and warning ribbon installation.
Relevant to the large underground electrical distribution systems commonly found on university campuses.
Although these proposals would benefit campus infrastructure, the CMP-3 transcript contains very little discussion directed specifically at educational occupancies. Topics such as healthcare facilities (Article 517), stadium emergency systems, data centers, laboratories as occupancies, residence halls, libraries, and central utility plants largely fall within the jurisdiction of other NEC Code-Making Panels such as CMP-1 and CMP-15 where Mike has been a Principal or Alternate for IEEE.
April 29, 2026
At the request of IEEE Joint IAS/PES Standards Michigan, Mike Anthony moved to CMP-3 from CMP-15.
Articles Under CMP 3
Article 300 — General Requirements for Wiring Methods and Materials
Article 335 — Instrumentation Tray Cable (in some references for the 2029 cycle)
Article 590 — Temporary Installations (being relocated/renumbered in the 2026 cycle, e.g., potentially to Article 140 in Chapter 1, as temporary wiring is not treated as a special occupancy)
Article 720 — Limited-Energy System Installations (new/general article covering wiring methods for limited-energy systems)
Article 723 — Raceways, Cable Routing Assemblies, and Cable Trays for Limited-Energy Systems (newly created in the 2026 cycle)
Article 725 — Class 2 and Class 3 Remote-Control, Signaling, and Power-Limited Circuits
Article 726 — Class 4 Fault-Managed Power Circuits and Equipment
Article 727 — Instrumentation Tray Cable
Article 728 — Fire-Resistive Cable Systems
Article 760 — Fire Alarm Systems (power-limited and non-power-limited portions)
CMP 3 also handles associated content in: Chapter 9 — Tables, including Tables 11(A) & (B) and Tables 12(A) & (B) (related to conductor properties and other supporting tables for the above topics).
Notes on Changes and Scope CMP 3 focuses on general wiring rules, cable types, raceways/trays for low-energy applications, and signaling/communications-related wiring (distinct from higher-power utilization equipment or special occupancies handled by other panels).
In the 2026 NEC cycle, there has been significant reorganization of Chapter 7 to consolidate limited-energy systems under articles like 720–726 (and related ones), moving away from older structures. This includes new articles for raceways/cable trays specific to limited-energy systems and adjustments to scopes for clarity.
Article 206 (Non-Power-Limited Remote-Control and Signaling Circuits) appears in some 2026-related references as newly designated or relocated material handled in this area. Temporary installations (Article 590) are transitioning out of “special” categories in restructuring efforts.
During today’s sessions of the IEEE E&H Committee and our own we will prepare draft proposals relevant to the safety and sustainability agenda of the USA education facility industry. Use the login credentials at the upper right of our home page.
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
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
The rapid growth of data centers presents genuine challenges to electric power systems: very large concentrated loads, accelerated interconnection schedules, new transmission requirements and concern over who ultimately pays for the necessary infrastructure. These problems deserve careful attention, but they are fundamentally engineering problems — and therefore problems capable of engineering solutions.
Electrical power systems have repeatedly adapted to new classes of load. Electrification of industry, air conditioning, electric heating and large computing facilities each altered planning assumptions in their time. Data centers will do the same.
Power engineers are already developing better methods for load forecasting, staged interconnection, demand response, energy storage, on-site generation and microgrids. Data centers themselves can become more flexible loads, reducing consumption during stressed grid conditions rather than operating continuously at maximum demand. Improved transmission planning, advanced protection and controls and better coordination between utilities, system operators and large customers will further reduce adverse effects.
The present difficulties should therefore not be mistaken for permanent conditions. Engineering practice evolves when operating experience reveals new constraints. The extraordinary concentration of electrical demand created by artificial intelligence will test the grid, but it will also accelerate improvements in how large loads are designed, connected, controlled and supplied.
1. Build vertically — Stack rack “white space” across three to five floors, including one or two below grade, to reduce building footprint and land consumption.
2. Make architecture an asset — Treat the exterior as an architectural statement appropriate to its community rather than as an anonymous industrial enclosure.
3. Support municipal infrastructure — Design electrical and standby-generation capacity to support critical municipal loads, including water and wastewater systems during major regional contingencies.
4. Co-locate emergency management functions — Provide space and resilient infrastructure for local or regional emergency management operations.
5. Provide community swing space — Incorporate adaptable space that can support sports, recreation and other community uses when not required for primary facility operations.
A data center need not be only a data center.A very large, extraordinarily well-powered and resilient building can return some of that resilience to the community hosting it.
How much irreversible infrastructure should a society build when a technological competitor may be able to obsolete the demand for it faster than the infrastructure can recover its capital cost? Nobody has to behave maliciously for it to happen.
Engineering has always advanced by converting apparent limits into tractable problems. New technologies commonly arrive before the infrastructure, standards and operating experience needed to support them. Railways, electric power, telecommunications, aviation and computing each produced genuine hazards and public anxieties before engineers learned how to manage them.
Solutions emerged in the fullness of time through measurement, experiment, failure analysis, improved materials, better design and the patient development of technical standards. Data centers belong to this tradition. Their scale creates difficult problems of power, cooling, reliability and community infrastructure, but difficulty is not novelty. Engineering proceeds by defining constraints, testing alternatives and building workable solutions.
A few thoughts off the beaten path:
Stack the white space. Vertical construction has precedent in multi-story urban data centers. Consider three to five floors plus basements as a community land-use mitigation strategy. A smaller footprint leaves more land available for housing, recreation, landscape and other community uses.
PC’s can, and probably will, reduce AI data center sizes. There is a real literature behind this idea, although researchers usually call it edge AI, collaborative inference, distributed inference, AI PCs, device-edge-cloud computing or volunteer computing, rather than “moving data-center load onto desktops.”
Think of data centers as urban energy assets. A 2025 study models data centers not simply as loads but as “heat-active urban energy prosumers.” Using the EPFL campus in Lausanne, the authors find that flexible computing and district-heating integration can allow a data center to contribute materially to the surrounding energy system. This supports the larger proposition that a facility consuming extraordinary amounts of community infrastructure should return infrastructure value to its host community. Waste-heat recovery provides one route. Yuan et al. review integration of data-center heat into district-heating networks through heat pumps, thermal storage and related systems. Aalto University — Data Center Waste Heat for District Heating Networks
Look for novel secondary uses. Terenius, Garraghan and Harper consider data-center waste heat for buildings, agricultural and commodity processes, energy storage and other social uses. Their case studies deliberately place data centers within different community settings rather than treating them as isolated industrial loads. Frontiers — A Material Social View on Data Center Waste Heat
The community scale reliability problem is not new:
This title sets the standard of care for construction, operation and maintenance of power and telecommunication infrastructure on the supply side of the point of common coupling. It is the first title to contemplate when weather disasters happen; with most public utilities bound to its best practice assertions by statute. Pre-print of Change Proposals for changes to appear in 2028 Edition will be available by 1 July 2025; with 24 March 2026 as the close date for comments on proposed changes.
The standard of care for electrical safety at high and low voltage is set by both the NEC and the NESC. There are gaps, however (or, at best “gray areas”) — the result of two technical cultures: utility power culture and building fire safety culture. There is also tradition. Local system conditions and local adaptation of regulations vary. Where there is a gap; the more rigorous requirement should govern safety of the public and workers.
The 2023 National Electrical Safety Code (NESC)– an IEEE title often mistaken for NFPA’s National Electrical Code (NEC) — was released for public use about six months ago; its normal 5-year revision cycle interrupted by the circumstances of the pandemic. Compared with the copy cost of the NEC, the NESC is pricey, though appropriate for its target market — the electric utility industry. Because the 2023 revision has not been effectively “field tested” almost all of the available support literature is, effectively, “sell sheets” for pay-for seminars and written by authors presenting themselves as experts for the battalions of litigators supporting the US utility industry. Without the ability to sell the NESC to prospective “insiders” the NESC would not likely be commercial prospect for IEEE. As the lawsuits and violations and conformance interests make their mark in the fullness of time; we shall see the 2023 NESC “at work”.
Change Proposals are now being accepted from the public for revisions to the 2023 Edition of the National Electrical Safety Code® #NESC through 15 May 2024.
The new code goes into effect 1 February 2023, but is now available for access on IEEE Xplore! Produced exclusively by IEEE, the National Electrical Safety Code (NESC) specifies best practices for the safety of electric supply and communication utility systems at both public and private utilities. The bibliography is expanding rapidly:
The IEEE NESC technical committee has released a “fast track” review of proposed changes to fault-managed power system best practice:
CP5605 Provides a definition of new Fault Managed Power System (FMPS) circuits used for the powering of
communications equipment clearly defines what constitutes a FMPS circuit for the purposes of application of the NESC
Rules of 224 and 344 https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXtAAAAADhMnPs
CP5606 Provides new definitions of Communication Lines to help ensure that Fault Managed Power Systems (FMPS)
circuits used for the exclusive powering of communications equipment are clearly identified as communications lines
and makes an explicit connection to Rule 224B where the applicable rules for such powering circuits are found. https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXpAAAAAFfvWIs
CP5607 The addition of this exception permits cables containing Fault Managed Power System (FMPS) circuits used for
the exclusive powering of communications equipment to be installed without a shield. https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXuAAAAAEEt3p4
CP5608 The addition of this exception permits cables containing Fault Managed Power System (FMPS) circuits used for
the exclusive powering of communications equipment to be installed without a shield. https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXvAAAAAGrzyeI
We refer them to the IEEE Education & Healthcare Facilities Committee for further action, if any.
August 5, 2022
We collaborate closely with the IEEE Education & Healthcare Facilities Committee (IEEE E&H) to negotiate the standard of care for power security on the #SmartCampus since many campus power systems are larger than publicly regulated utilities. Even when they are smaller, the guidance in building the premise wiring system — whether the premise is within a building, outside the building (in which the entire geography of the campus footprint is the premise), is inspired by IEEE Standards Association administrated technical committees.
Northeast Community College | Norfolk, Nebraska
Today we begin a list of noteworthy changes to be understood in the next few Power colloquia. See our CALENDAR for the next online meeting.
New rules 190 through 195 cover photovoltaic generating stations. Rule 116c adds an exception for short lengths of insulated power cables and short-circuit protection if the situation involves fewer than 1,000 volts.
Rule 320B has been revised to clarify separations that apply to communications and supply in different conduit systems.
Table 410-4 is based on the latest arc flash testing on live-front transformers.
Rule 092A adds an exception allowing protection, control, and safety battery systems to not be grounded.
Rules 234 B1, C1, D1 were revised to better present vertical and horizontal wind clearances, and to coordinate requirements with the new Table 234-7.
Rule 120A was revised to provide correction factors for clearances on higher elevations.
Table 253-1 has been revised to reduce the load factor for fiber-reinforced polymer components under wire tension—including dead ends—for Grade C construction.
Rule 410A now requires a specific radio-frequency safety program for employees who might be exposed.
In the Clearances section, as well as in the specification of the Grade of Construction in Table 242-1, the Code further clarifies the use of non-hazardous fiber optic cables as telecom providers continue to expand their networks.
Revisions in the Strength & Loading sections include modified Rule 250C, which addresses extreme wind loading for overhead lines. Two wind maps are now provided instead of the previous single one. A map for Grade B, the highest grade of construction, with a Mean Recurrence Interval (MRI) of 100 years (corresponding to a one percent annual probability of occurrence) is provided in place of the previous 50–90-year MRI map. For Grade C construction, a separate 50-year MRI (two percent annual probability of occurrence) map is now provided. In the previous Code, a factor was applied to the 50–90-year MRI map for application to Grade C.
Changes were also made to the method of determining the corresponding wind loads, consistent with the latest engineering practices as an example of a Code revision focused on public safety, the ground end of all anchor guys adjacent to regularly traveled pedestrian thoroughfares, such as sidewalks, and similar places where people can be found must include a substantial and conspicuous marker to help prevent accidents. The previous Code did not require the marking of every such anchor guy.
Significant revisions were made in Section 14 covering batteries. Previous editions of the code were based on lead-acid technology and batteries only used for backup power. The 2023 Code incorporates the new battery technologies and addresses energy storage and backup power.
A new Section 19 of the code covers photovoltaic generating stations, with sections addressing general codes, location, grounding configurations, vegetation management, DC overcurrent protection, and DC conductors. These new rules accommodate large-scale solar power projects.
In the Clearances section, all rules for wireless antenna structures have been consolidated in the equipment section (Rule 238 and 239), which makes the Code more user-friendly.
A new subcommittee was created focusing on generating stations, with the original subcommittee continuing to address substations.
A working group is investigating Fault Managed Power Systems (FMPS) cables as the technology may be used for 5G networks. The team is looking at possible impacts, including clearances and work rules.
Several proposals recommending improvements to the 2017 National Electrical Safety Code (NESC) were submitted to the IEEE subcommittees drafting the 2022 revision of the NESC. Some of the proposals deal with coordination with the National Electrical Code — which is now in its 2023 revision cycle. Keep in mind that that NESC is revised every 5 years at the moment; the NEC is revised every 3 years.
The original University of Michigan standards advocacy enterprise has been active in writing the NESC since the 2012 edition and set up a workspace for use by electrical professionals in the education industry. We will be using this workspace as the 2022 NESC continues along its developmental path:
The NESC is a standing item on the 4-times monthly teleconferences of the IEEE Education & Healthcare Facilities committee. The next online meeting is shown on the top menu of the IEEE E&H website:
We have a copy of the first draft of the 2023 NESC and welcome anyone to join us for an online examination during any of Power & ICT teleconferences. See our CALENDAR for the next online meeting.
Business unit leaders, facility managers and electrical engineers working in the education facilities industry may be interested in the campus power system reliability database. Forced outages on large research campuses, for example, can have enterprise interruption cost of $100,000 to $1,000,000 per minute. The campus power system forced outage database discriminates between forced outages attributed to public utility interruptions and forced outages attributed to the university-owned power system. The E&H committee will convey some of the discipline applied by the IEEE 1366 technical committee into its study of campus power systems and, ultimately, setting a benchmark for the standard of care for large university power systems.
* The IEEE changed the nominal date of the next edition; likely owed to pandemic-related slowdown typical for most standards developing organizations.

Today at the usual hour we revisit previous coverage of standards action affecting the essential works of educational settlements and bring them forward. We will also review open public consultations on standards incorporated by reference into public law. Use the login credentials at the upper right of our home page.
The internationalization of the education industry continues at a brisk pace and so do the enterprises that support the primary business of learning, teaching and discovering. Educational campuses, and related university-affiliated medical research and healthcare enterprises, represent one of the largest assets owned and operated by any state.
In a state such as the State of Michigan, for example, with a gross state product of about $500 billion, the value of public real property assets may be on the order of $50 billion*. If taking 2 percent off the cost owning, operating and maintaining those assets every year resulted in a savings of $1 billion million every year simply because conformance to a standard that reduced destructive competition and redundancy is meaningful, then those agencies should pay attention. Alas, they do not, or not yet; a condition we describe in our ABOUT.
There is no reason to believe that internationalization of campus facility management practices cannot be as transformative to an industry as the ISO 9000 catalog of management standards were to, say, to the Michigan automobile industry 50-odd years ago. In other words, the Michigan experience with globalization of its core industry was hastened precisely because of the conformance template that the ISO-9000 suite provided.
ISO/TC 267 Project Kickoff Meeting | Berlin 2012 | The University of Michigan was the first US university to participate in the launch of this standard and acted as a technical liaison for IFMA.
The business plan for this committee is linked below and provides a high level overview of committee goals and organization:
At the moment ANSI has identified the US TAG Administrator as the International Facility Management Association however direct management of the US delegation is also being supported by ANSI staff.
