Modular Office Furniture Wiring

2026 NEC CMP-18 Public Input Report

CMP-18 Second Draft Report

“Office in a Small City” (1953) / Edward Hopper

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:

Public Access 2023 National Electrical Code

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).

Seneca College / Toronto

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:

Public Input Report – 2023 National Electrical Code Panel 7 

Public Input Report – 2023 National Electrical Code Panel 18

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):

Public Input Report – 2023 National Electrical Code Panel 2

,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.

2029 National Electrical Code Panel 3

Electrical Safety Stack

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 advocacy 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 590 Temporary Installations

Chapter 7 Specific Conditions for Information Technology

Chapter 9 Conductor Properties Tables

Public Input on the 2029 Edition will be received until April 9, 2026.

 

Luminaires, Lampholders, and Lamps

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.
  • Article 210 – Covers branch circuit requirements, including those for lighting circuits in dwellings and commercial buildings.
  • Article 220 – Provides guidelines for calculating lighting loads.
  • Article 225 – Addresses outside lighting installations.
  • Article 240 – Covers overcurrent protection for lighting circuits.
  • Article 250 – Deals with grounding and bonding, which is essential for lighting circuits.
  • Article 300 – Covers general wiring methods that apply to lighting circuits.

We have done a fair amount of work on this topic over the years, including writing the chapter on campus outdoor lighting for the soon-to-be-released IEEE 3001.9 Recommended Practice for the Design of Power Systems Supplying Lighting Systems in Commercial and Industrial Facilities.   

For our meeting please refer to the workspace we have set up for the 2026 Revision of the NEC:

Standard for Parking Structures

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:

Fire Alarm & Signaling Code

“Prometheus Bound” | Thomas Cole (1847)

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

Data Center Wiring

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.

“Bookwheel” Early Data Center

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.

We will use these in our exploration of what we might propose for improvements in the 2026 revision.  Public comment on the First Draft of the 2026 Edition will be received until August 28th.

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.

Life Safety Code

Educational and Day-Care Occupancies (July 23, 2025 Second Draft Transcript)

The Life Safety Code addresses those construction, protection, and occupancy features necessary to minimize danger to life from the effects of fire, including smoke, heat, and toxic gases created during a fire.   It is widely incorporated by reference into public safety statutes; typically coupled with the consensus products of the International Code Council.   It is a mighty document — one of the NFPA’s leading titles — so we deal with it in pieces; consulting it for decisions to be made for the following:

(1) Determination of the occupancy classification in Chapters 12 through 42.

(2) Determination of whether a building or structure is new or existing.

(3) Determination of the occupant load.

(4) Determination of the hazard of contents.

There are emergent issues — such as active shooter response, integration of life and fire safety systems on the internet of small things — and recurrent issues such as excessive rehabilitation and conformity criteria and the ever-expanding requirements for sprinklers and portable fire extinguishers with which to reckon.  It is never easy telling a safety professional paid to make a market for his product or service that it is impossible to be alive and safe.  It is even harder telling the dean of a department how much it will cost to bring the square-footage under his stewardship up to the current code.

The 2021 edition is the current edition and is accessible below:

NFPA 101 Life Safety Code Free Public Access

Public input on the 2027 Revision will be received until June 4, 2024.  Public comment on the Second Draft 2027 Revision will be received until March 31, 2026.

 

Since the Life Safety Code is one of the most “living” of living documents — the International Building Code and the National Electric Code also move continuously — we can start anywhere and anytime and still make meaningful contributions to it.   We have been advocating in this document since the 2003 edition in which we submitted proposals for changes such as:

• A student residence facility life safety crosswalk between NFPA 101 and the International Building Code

• Refinements to Chapters 14 and 15 covering education facilities (with particular attention to door technologies)

• Identification of an ingress path for rescue and recovery personnel toward electric service equipment installations.

• Risk-informed requirement for installation of grab bars in bathing areas

• Modification of the 90-minute emergency lighting requirements rule for small buildings and for fixed interval testing

• Modification of emergency illumination fixed interval testing

• Table 7.3.1 Occupant Load revisions

• Harmonization of egress path width with European building codes

There are others.  It is typically difficult to make changes to stabilized standard though some of the concepts were integrated by the committee into other parts of the NFPA 101 in unexpected, though productive, ways.  Example transcripts of proposed 2023 revisions to the education facility chapter is linked below:

Chapter 14 Public Input Report: New Educational Occupancies

Since NFPA 101 is so vast in its implications we list a few of the sections we track, and can drill into further, according to client interest:

Chapter 3: Definitions

Chapter 7: Means of Egress

Chapter 12: New Assembly Occupancies

Chapter 13: Existing Assembly Occupancies

First Draft: Fundamentals of the Fire Code (FCC-FUN)

Special Equipment, Processes and Hazardous Materials (FCC-HAZ)

Building Systems and Special Occupancies (FCC-OCP)

Public comment on the First Draft of the 2027 revision will be received until April 24, 2025.

We include NFPA 1 on our periodic fire safety colloquia — identified by the mnemonic Prometheus — and march along peak interests.

Campus fire safety is domain relatively well-covered by other organizations such as the Center for Campus Fire Safety and HigherEd Safety so we place NFPA 1 in the middle of our priority tier.   We are more interested in the harmonization of NFPA 1 with a competitor title International Fire Code; published by the International Code Council; to wit:

International Fire Code:   The purpose of this code is to establish the minimum requirements consistent with nationally recognized good practice for proving a reasonable level of life safety and property protection from the hazards of fire, explosion or dangerous conditions in new and existing buildings, structures or premises and to provide a reasonable level of safety to fire fighters and emergency responders during emergency operations

Fire Code: The scope includes, but is not limited to, the following: (1) Inspection of permanent and temporary buildings, processes, equipment, systems, and other fire and related life safety situations (2) Investigation of fires, explosions, hazardous materials incidents, and other related emergency incidents (3) Review of construction plans, drawings, and specifications for life safety systems, fire protection systems, access, water supplies, processes, hazardous materials, and other fire and life safety issues (4) Fire and life safety education of fire brigades, employees, responsible parties, and the general public (5) Existing occupancies and conditions, the design and construction of new buildings, remodeling of existing buildings, and additions to existing buildings (6) Design, installation, alteration, modification, construction, maintenance, repairs, servicing, and testing of fire protection systems and equipment (7) Installation, use, storage, and handling of medical gas systems (8) Access requirements for fire department operations (9) Hazards from outside fires in vegetation, trash, building debris, and other materials (10) Regulation and control of special events including, but not limited to, assemblage of people, exhibits, trade shows, amusement parks, haunted houses, outdoor events, and other similar special temporary and permanent occupancies (11) Interior finish, decorations, furnishings, and other combustibles that contribute to fire spread, fire load, and smoke production (12) Storage, use, processing, handling, and on-site transportation of flammable and combustible gases, liquids, and solids (13) Storage, use, processing, handling, and on-site transportation of hazardous materials (14) Control of emergency operations and scenes (15) Conditions affecting fire fighter safety (16) Arrangement, design, construction, and alteration of new and existing means of egress

Note that both ICC and NFPA parent fire safety documents are developed on coincident 3-year cycles.

Interconnected Electric Power Production Sources “Microgrids”

“Landscape with a Farm House and Windmill” (1680) / Jacob Isaaksz van Ruisdael

We have always taken a forward-looking approach to the National Electrical Code (NEC) because there is sufficient supply of NEC instructors and inspectors and not enough subject matter experts driving user-interest ideas into it.  Today we approach the parts of the 2023 NEC that cover wiring safety for microgrid systems; a relatively new term of art that appropriates safety and sustainability concepts that have existed in electrotechnology energy systems for decades.

Turn to Part II of Article 705 Interconnected Electric Power Production Sources:

Free Access 2023 National Electrical Code

You will notice that microgrid wiring safety is a relatively small part of the much larger Article 705 Content.   There were relatively minor changes to the 2017 NEC in Section 705.50  — but a great deal of new content regarding Microgrid Interconnection Devices, load side connections, backfeeding practice and disconnecting means — as can be seen in the transcripts of Code-Making Panel 4 action last cycle:

Code‐Making Panel 4 Public Input Report (692 Pages)

Code-Making Panel 4 Public Comment Report (352 Pages)

Keep in mind that the NEC says nothing (or nearly very little, in its purpose stated in Section 90.2) about microgrid economics or the life cycle cost of any other electrical installation.  It is the claim about economic advantages of microgrids that drive education facility asset management and energy conservation units to conceive, finance, install, operate and — most of all — tell the world about them.

In previous posts we have done our level best to reduce the expectations of business and finance leaders of dramatic net energy savings with microgrids — especially on campuses with district energy systems.  Microgrids do, however, provide a power security advantage during major regional contingencies — but that advantage involves a different set of numbers.

Note also that there is no user-interest from the education facility industry — the largest non-residential building construction market in the the United States — on Panel 4.   This is not the fault of the NFPA, as we explain in our ABOUT.

The 2023 NEC was released late last year.

 

The 2026 revision cycle is in full swing with public comment on the First Draft receivable until August 24, 2024.  Let’s start formulating our ideas using the 2023 CMP-4 transcripts.   The link below contains a record of work on the 2023 NEC:

College and university campuses distribute electric energy in tranches of 10 to 250 megawatts; typically at voltages above 1000 VAC and are generally regarded as load-side services (or regulated utility customers). Two fairly stable sections of the National Electrical Code set the standard of care for these systems — Part III of Article 110 and Article 495.

We will examine them during today’s High Voltage Electric Service colloquium.
