Many land grant colleges and universities are stewards of agricultural facilities that require reliable electrical power that is safe and sustainable for livestock well off the core campus distribution grid. Today we examine the 2026 National Electrical Code safe electric service rules with an eye toward the close date of April 6th for public input on the 2029 NEC.
Many land grant colleges and universities are stewards of agricultural facilities that require reliable electrical power that is safe and sustainable for livestock and animal habitat for sporting.
The premise wiring rules for hazardous university owned buildings have been relatively stable. Electrical professionals are guided by:
Farm Load Calculations of Part V of Article 220,
Corrosion mitigation with appropriate specification of power chain wiring
Stray voltage and the equipotential plane
Interactivity with regulated utility power sources.
Public response to the First Draft of the 2026 National Electrical Code will be received until August 28, 2024. We coordinate our approach to the entire NFPA electrical suite with the IEEE Education & Healthcare Facilities Committee which meets 4 times monthly. We typically refer to previous transcripts of technical committee actions to inform any changes (improvements) that we propose, if any.
We maintain this issue on the standing agenda of our Power and Nourriture (Food) colloquia. Feel free to join us with the login credentials at the upper right of our home page.
Today at 16:00 UTC we review best practice for engineering and installing the point of common coupling between an electrical service provider its and an purchasing — under the purview of NEC CMP-10.

The relevant passages of the National Electrical Code are found in Article 230 and Article 495. We calibrate our attention with the documents linked below. These are only representative guidelines:
We are in the process of preparing new (original, and sometimes recycled) proposals for the 2026 National Electrical Code, with the work of Code Panel 10 of particular relevance to today’s topic:
First Draft Meetings: January 15-26, 2024 in Charleston, South Carolina
Electrical meter billing standards are generally regulated at the state or local level, with guidelines provided by public utility commissions or similar regulatory bodies. These tariff sheets are among the oldest in the world. There are some common standards for billing and metering practices, including:
Meter Types: There are various types of meters used to measure electricity consumption, including analog (mechanical) meters, digital meters, and smart meters. Smart meters are becoming more common and allow for more accurate and real-time billing.
Billing Methodology:
Residential Rates: Most residential customers are billed based on kilowatt-hours (kWh) of electricity used, which is the standard unit of energy.
Demand Charges: Some commercial and industrial customers are also subject to demand charges, which are based on the peak demand (the highest amount of power drawn at any one point during the billing period).
Time-of-Use Rates: Some utilities offer time-of-use (TOU) pricing, where electricity costs vary depending on the time of day or season. For example, electricity may be cheaper during off-peak hours and more expensive during peak hours.
Meter Reading and Billing Cycle:
Monthly Billing: Typically, customers receive a bill once a month, based on the reading of the electricity meter.
Estimation: If a meter reading is not available, some utilities may estimate usage based on historical patterns or average usage.
Smart Meter Readings: With smart meters, some utilities can provide daily or even hourly usage data, leading to more precise billing.
Meter Standards: The standards for electrical meters, including their accuracy and certification, are set by national organizations like the National Institute of Standards and Technology (NIST) and the American National Standards Institute (ANSI). Meters must meet these standards to ensure they are accurate and reliable.
Utility Commission Regulations: Each state has a utility commission (such as the California Public Utilities Commission, the Texas Public Utility Commission, etc.) that regulates the rates and billing practices of electricity providers. These commissions ensure that rates are fair and that utilities follow proper procedures for meter readings, billing cycles, and customer service
Large University “Utilities”. Large colleges and universities that generate and distribute some or all of their electric power consumption have developed practices to distribute the cost of electricity supply to buildings. We will cover comparative utility billing practices in a dedicated colloquium sometime in 2025.
Starting 2025 — and continuing through 2026 — we change our approach to responding to public consultation in the development of the NFPA catalog. Draft proposals are listed at the bottom of this page.
Here are 10 possible definitions or terms for college student housing facilities shared by 4 to 6 unrelated students:
Dormitory Suite: A shared living space within a dormitory building, featuring individual or shared bedrooms, a common living area, and sometimes a small kitchen or bathroom, designed for 4–6 students.
Apartment-Style Housing: On-campus or off-campus apartments with multiple bedrooms, a shared kitchen, living room, and bathroom(s), accommodating 4–6 students.
Cooperative Housing (Co-op): A student-managed housing unit where 4–6 unrelated students share responsibilities for chores, cooking, and maintenance while living together in a house or apartment.
Shared Residence Hall Unit: A section of a residence hall with private or semi-private bedrooms and shared common areas like a lounge or kitchen, housing 4–6 students.
Cluster Housing: A group of bedrooms clustered around a shared living space, often including a kitchenette or bathroom, designed for 4–6 students in a residence hall or apartment complex.
Pod-Style Housing: A modern dorm layout where 4–6 students share a compact unit with individual or paired bedrooms, a common area, and shared facilities like a bathroom or kitchen.
Student Townhouse: A multi-level housing unit, typically off-campus or in university-owned complexes, with shared living spaces and multiple bedrooms for 4–6 students.
Quad or Hex Apartment: An apartment specifically designed for 4 (quad) or 6 (hex) students, featuring shared amenities like a kitchen, living room, and bathroom(s).
Communal House: An off-campus house leased by 4–6 students, with shared spaces like a living room, kitchen, and bathrooms, often independently rented but sometimes university-affiliated.
Living-Learning Community Unit: A shared housing arrangement for 4–6 students in a residence hall, centered around a specific academic or thematic focus, with shared common areas to foster collaboration.
These definitions reflect common housing arrangements for unrelated college students, based on typical university housing structures and off-campus options.
Should show up in NFPA 101 and referral to them is appreciated.
Here we shift our perspective 120 degrees to understand the point of view of the Producer interest in the American national standards system (See ANSI Essential Requirements). The title of this post draws from the location of US and European headquarters. We list proposals by a successful electrical manufacturer for discussion during today’s colloquium:
2026 National Electrical Code
CMP-1: short circuit current ratings, connections with copper cladded aluminum conductors, maintenance to be provided by OEM, field markings
CMP-2: reconditioned equipment, receptacles in accessory buildings, GFCI & AFCI protection, outlet placement generally, outlets for outdoor HVAC equipment(1)
(1) Here we would argue that if a pad mount HVAC unit needs service with tools that need AC power once every 5-10 years then the dedicated branch circuit is not needed. Many campuses have on-site, full-time staff that can service outdoor pad mounted HVAC equipment without needing a nearby outlet. One crew — two electricians — will run about $2500 per day to do anything on campus.
CMP-3: No proposals
CMP-4: solar voltaic systems (1)
(1) Seems reasonable – spillover outdoor night time lighting effect upon solar panel charging should be identified.
CMP-5: Administrative changes only
CMP-6: No proposals
CMP-7: Distinction between “repair” and “servicing”
CMP-10: Short circuit ratings, service disconnect, disconnect for meters, transformer secondary conductor, secondary conductor taps, surge protective devices, disconnecting means generally, spliced and tap conductors, more metering safety, 1200 ampere threshold for arc reduction technology, reconditioned surge equipment shall not be permitted, switchboard short circuit ratings
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
NFPA 72 National Fire Alarm and Signaling Code is one of the core National Fire Protection Association titles widely incorporated by reference into public safety legislation. NFPA 72 competes with titles of “similar” scope — International Fire Code — developed by the International Code Council. We place air quotes around the word similar because there are gaps and overlaps depending upon whether or not each is adopted partially or whole cloth by the tens of thousands of jurisdictions that need both.
Our contact with NFPA 72 dates back to the early 2000’s when the original University of Michigan advocacy enterprise began challenging the prescriptive requirements for inspection, testing and maintenance (IT&M) in Chapter 14. There are hundreds of fire alarm shops, and thousands of licensed fire alarm technicians in the education facility industry and the managers of this cadre of experts needed leadership in supporting their lower #TotalCostofOwnership agenda with “code-writing and vote-getting”. There was no education industry trade association that was even interested, much less effective, in this space so we had to do “code writing and vote getting” ourselves (See ABOUT).
Code writing and vote getting means that you gather data, develop relationships with like minded user-interests, find agreement where you can, then write proposals and defend them at NFPA 72 technical committee meetings for 3 to 6 years. Prevailing in the Sturm und Drang of code development for 3 to 6 years should be within the means of business units of colleges and universities that have been in existence for 100’s of years. The real assets under the stewardship of these business units are among the most valuable real assets on earth.
Consider the standard of care for inspection, testing and maintenance. Our cross-cutting experience in over 100 standards suites allows us to say with some authority that, at best the IT&M tables of NFPA 72 Chapter 14 present easily enforceable criteria for IT&M of fire alarm and signaling systems. At worst, Chapter 14 is a solid example of market-making by incumbent interests as the US standards system allows. Many of the IT&M requirements can be modified for a reliability, or risk-informed centered maintenance program but fire and security shops in the education industry are afraid to apply performance standards because of risk exposure. This condition is made more difficult in large universities that have their own maintenance and enforcement staff. The technicians see opportunities to reduce IT&M frequencies — thereby saving costs for the academic unit facility managers — the enforcement/compliance/conformity/risk management professionals prohibit the application of performance standards. They want prescriptive standards for bright line criteria to make their work easier to measure.
While we have historically focused on Chapter 14 we have since expanded our interest into communication technologies within buildings since technicians and public safety personnel depend upon them. Content in Annex G — Guidelines for Emergency Communication Strategies for Buildings and Campuses — is a solid starting point and reflects of our presence when the guidance first appeared in the 2016 Edition. We shall start with a review of the most recent transcript of the NFPA Technical Committee on Testing and Maintenance of Fire Alarm and Signaling Systems
Public comment of the First Draft of the 2025 Edition is receivable until May 31, 2023. As always, we encourage direct participation in the NFPA process by workpoint experts with experience, data and even strong opinions about shortcomings and waste in this discipline. You may key in your proposals on the NFPA public input facility linked below:
You will need to set up a (free) NFPA TerraView account. Alternatively, you may join us any day at 11 AM US Eastern time or during our Prometheus or Radio colloquia. See our CALENDAR for the online meeting.

Modular furniture systems with integral power and telecommunication fittings require attention to power and digital pathways. “Modular systems furniture” is a generic term for bundles of panels, worksurfaces, shelves, and other items sold by a single manufacturer as a package for furnishing offices. The modular furniture system environment is characterized by close proximity to electrical energy. Where there is electrical energy there are concerns for shock and fire safety.
Fire safety considerations appear in NFPA 70 National Electrical Code (NEC)– generally in Articles 210 (Branch Circuits), Article 220 (Branch Circuit, Feeder and Service Load Calculations) — and with more specific safety considerations appearing in Articles 604 (Manufactured Wiring Systems) and Article 605 (Office Furnishings). The current edition of the National Electrical Code is linked below:
Over the past 30-odd years modular furniture manufacturers have worked out a lot of the bugs in products; making it easier for furniture contractors to deliver a safer and more effective installation. What remains are site-specific conditions — such as lighting load, current draw of space heaters and personal air conditioners through the furniture power pathway — that must be reckoned with. A sample of other considerations:
Harmonic heating of the furniture pathway caused by non-linear, harmonic load
The risk of double-phasing when circuit breakers are joined with handle ties back at the panelboard and share a neutral
Any lighting equipment used with the partitions must have of properly sized cord no more than 9 ft long
Modularity in power tap cords (“whips’) between furniture raceways and the first gathering point
There are other safety and sustainability issues related to USB outlets, and data/voice outlets[2] that we will cover in another post and in our collaborations with IEEE SCC-18 and the IEEE Education & Healthcare Facilities Committee (IEEE E&H).

We find office wiring a relatively lively “promontary” in safety and sustainability circles. The transcript of debate among interior wiring experts is always a good place to listen in on the technical discussion; linked below:
We find manufactured wiring concepts tracking that effects office occupancies for all industries. Market incumbents continue advocacy for more ground fault and tamper-resistant receptacles in day care and gymnasium.
A more significant debate tracks in Chapter 2 — related to office modular furniture wiring because electrical load calculations determine how designers specify branch circuits for all occupancy classifications present in education communities (which is nearly every occupancy type defined in the International Building Code):
,Standards Michigan, beginning with its inspiration in the original University of Michigan standards advocacy enterprises, has a long and storied engagement with Chapter 2 of the NEC covered here and also academic literature and also in research sponsored by NFPA’s Fire Protection Research Foundation.
We always encourage our workpoint experts in the thousands of electrical and telecommunication units in the education and healthcare facilities industry to participate directly in the NFPA Code Development process (CLICK HERE to join a committee).
Since both the National Electrical Code and the National Electrical Safety Code revision cycles are roughly coincident in 2021 we working on electrical power issues every day, collaborating with the IEEE E&H Committee. Online meetings are open to everyone.
Best wiring safety practice for the illumination of educational settlement occupancies is scattered throughout the National Electrical Code with primary consideration for wiring fire safety:
Article 410 – Covers the installation of luminaires (fixtures), lampholders, and lamps, including requirements for wiring, grounding, and support.
The renovated Schwarzman Center at Yale now features dynamic new communal areas, a refreshed historic dining hall and eye-catching exterior lighting, enhancing the campus experience.
Tallinna Ülikool | University of Estonia | Parking place art
Parking — the lack of it, the cost of it — has always been a sensitive issue in education communities. Into the mix add the expansion of electric vehicle charging stations, ride sharing, and micromobility. Their construction characteristics make them ideal locations for storage enterprises and emergency generators. NFPA 88A Standard for Parking Structures asserts best practice of a small but important part of it; the construction and protection of, as well as the control of hazards in, open and enclosed parking structures. Things get complicated with other occupancy classes merge with it; especially so when electric vehicle battery fires present another order of magnitude of risk.
The 2023 Edition (recently released) can be read in the link below:
Note the concern for the overlap and space between this title and passages in International Code Council catalog. We limit our concern for fire safety and more education communities build high rise student accommodation with integral parking structures. The bibliography is extensive (References Pages 92 – 99):
The 2027 edition of this standard is open for public input until June 4, 2024. CLICK HERE to get started on your own.
We hold this title on the standing agenda of our Prometheus and Mobility colloquium. See our CALENDAR for the next online meeting; open to everyone.
The bookwheel, also known as a revolving bookcase, was invented by an Italian scholar and polymath named Agostino Ramelli. Ramelli was born in 1531 in Ponte Tresa, a town in present-day Italy, and he lived during the Renaissance period.
Ramelli’s invention, described in his work titled “Le diverse et artificiose machine del capitano Agostino Ramelli” (The Various and Ingenious Machines of Captain Agostino Ramelli), was published in 1588. This book showcased a collection of 195 mechanical devices.
Ramelli’s work contributed to the growing interest in mechanical inventions during the Renaissance period. His bookwheel design remains a fascinating example of early engineering and ingenuity, highlighting the desire for knowledge and practical solutions in the pursuit of learning and scholarly endeavors.
The standard of care for wiring safety for data centers — a continually expanding presence in education communities even before the pandemic — is established in National Electrical Code Articles 645 (Information Technology Equipment), Article 646 (Modular Data Centers) and Article 647 (Sensitive Electronic Equipment). You will notice that these articles cover the topic comprehensively and bear the imprint of competing Producer-Interest groups. There are no User-Interest representatives on Code-Making Panel 12 that represent the final fiduciary in education communities even though education communities are one of the largest markets for information and communication technology systems.
Transcripts of technical committee action during the 2026 revision (CMP-16) are linked below because they will inform our recommendations for the 2026 National Electrical Code. Keep in mind that the Technical Correlating Committee is moving content around the Code in order to make the NEC easier to use by experts.
The transcripts of technical committee action during the 2023 revision are linked below because they will inform our recommendations for the 2026 National Electrical Code.
The issues that have been in play in these articles of the NEC are familiar to veterans of the “food fight” – occupancy classification, cable specifications, fire protection, ventilation, energy consumption, surge protection, licensing of engineers. etc. We look for market-making excesses by opposing stakeholders that seek to limit their risk while raising the (financial) risk to education communities.
We encourage our colleagues to participate in the NFPA code development process directly. We also encourage stakeholders in education communities — students, faculty and staff to join us during any of the teleconferences we co-host with the IEEE Education & Healthcare Facilities Committee 4 times monthly in both European and American time zones. See our CALENDAR for the next online meeting.
