National Electrical Definitions

NFPA Glossary of Terms

International Building Code Chapter 2: Definitions

International Electrotechnical Commission: Electropedia

Because electrotechnology changes continually, definitions (vocabulary) in its best practice literature changes continually; not unlike any language on earth that adapts to the moment and place.

The changes reflect changes in technology or changes in how the technology works in practice; even how the manufacturers create adaptations to field conditions by combining functions.   Any smart electrical component has a digital language embedded in it, for example.

Consider the 2023 National Electrical Code.  Apart from many others the NEC will contain a major change to Article 100 (Definitions); the subject of elevated debate over the past three years.

When we refer “language” we must distinguish between formal language, informal language, colloquial language and dialect which may differ the language spoken, language written at the office and language used on the job site.  “Terms of art”

2026 National Electrical Code | CMP-1 Second Draft Report 

FREE ACCESS: 2020 National Electrical Code (NFPA 70)

2023 NEC Public Input Report CMP-1 (868 pages)

2023 NEC Second Draft Public Comment Report (914 pages)

Are these terms (or, “terms of art”) best understood in context (upstream articles in Chapters 4 through 8) — or should they be adjudicated by the 14 Principals of Code Making Panel 1?   The answer will arrive in the fullness of time.   Many changes to the National Electrical Code require more than one cycle to stabilize.

Code Making Panel 1 has always been the heaviest of all NEC panels.  As explained n our ABOUT, the University of Michigan held a vote in CMP-1 for 20+ years (11 revision cycles) before moving to the healthcare facilities committee for the IEEE Education & Healthcare Facilities Committee.  Standards Michigan continues its involvement on behalf of the US education facility industry — the second largest building construction market.  There is no other pure user-interest voice on any technical committee; although in some cases consulting companies are retained for special purposes.

To serve the purpose of making NFPA 70 more “useable” we respect the Standards Council decision to make this change if it contributes to the viability of the NFPA business model.  We get to say this because no other trade association comes close to having as enduring and as strong a voice:  NFPA stands above all other US-based SDO’s in fairness and consideration of its constituency.  The electrical safety community in the United States is a mighty tough crowd.

If the change does not work, or work well enough, nothing should prohibit reversing the trend toward “re-centralizing” — or “de-centralizing” the definitions.

Public comment on the First Draft of the 2026 Edition will be received until August 28, 2024. 

Technical Committees meet during the last half of October to respond to public comment on the First Draft of the 2026 National Electrical Code.

NFPA 731: Standard for the Installation of Premises Security Systems

Library of Alexandria

NFPA 730 Guide to Premise Security guide describes construction, protection, occupancy features, and practices intended to reduce security vulnerabilities to life and property.  Related document — NFPA 731 Standard for the Installation of Electronic Premises Security Systems covers the application, location, installation, performance, testing, and maintenance of electronic premises security systems and their components.

The original University of Michigan standards advocacy enterprise (see ABOUT) began following the evolution of NFPA 730 and NFPA 731 since the 2008 Edition.   That enterprise began a collaboration  with trade associations and subject matter experts from other universities (notably Georgetown University and Evergreen State University) to advocate user-interest concepts in the 2011 edition.    A summary of advocacy action is summarized in the links below:

This title remains on the standing agenda of our Security colloquia.  See our CALENDAR for the next online meeting; open to everyone.

Fireplace Safety


Many accommodations such as dormitories, fraternities and sororities have working fireplaces — wood burning and natural gas.  Community spaces such as student unions, libraries and recreation spaces also have fireplaces as a central feature.

The purpose of NFPA 211 is to reduce fire hazards by discovering and promulgating best practice for the safe removal of flue gases, the proper installation of solid fuel-burning appliances, and the correct construction and installation of chimneys, fireplaces, and venting systems.  The current 2019 Edition is linked below:

Free Access: NFPA 221 Standard for Chimneys, Fireplaces, Vents, and Solid Fuel-Burning Appliances

The 2024 has been released.  To guide our inquiry into safety and sustainability concepts for the 2027 Edition we like review the developmental transcripts of previous edition:

Electrical Inspector Professional Qualifications

Electrical Training

Compact Muon Solenoid / European Organization for Nuclear Research

NFPA 1078 Standard for Electrical Inspector Professional Qualifications identifies the minimum job performance requirements for electrical inspectors.   Qualifications for electrical inspectors are heavily regulated by state public safety agencies.   Many, if not most electrical inspectors are former electricians.   This means that part of their career has been spent working as an  Labor/Installer/Maintenance stakeholder, and another part of their career has been spend as an Enforcement stakeholder.  (See NFPA Classification of Committee Members).   This can be a sensitive condition in large research universities that have a resident full-time enforcement staff ; the subject of a separate post.

Public input on the 2028 revision will be received until June 4, 2025

We have found that passions are elevated among stakeholders whenever compliance and conformance revenue is involved — i.e. in any consensus product that covers labor (i.e. billable hours).

We include this standard on the standing agenda of our monthly Human Resource, Power and Infotech teleconferences.   See our CALENDAR for the next online meeting; open to everyone.

Outdoor Deicing & Snow Melting

Electrical Safety

“Snow at Argenteuil” | Claude Monet (1875)

Today our focus turns to outdoor electric deicing and snow melting wiring systems identified as suitable for the environment and installed in accordance with the manufacturer’s instructions.  They work silently to keep snow load from caving in roofs and icicles falling from gutters onto pedestrian pathways.

While the voltage and ampere requirement of the product itself is a known characteristic, the characteristic 0f the wiring pathway — voltage, ampere, grounding, short circuit, disconnect and control — is relatively more complicated and worthy of our attention.   Articles 426-427 of the National Electrical Code is the relevant part of the NEC

Free Access 2023 National Electrical Code

Insight into the ideas running through technical committee deliberations is provided by a review of Panel 17 transcripts:

2023 NEC Panel 17 Public Input Report (633 pages)

2023 NEC Panel 17 Public Comment Report (190 pages)

We hold Articles 427 in the middle of our priority ranking for the 2023 NEC.   We find that the more difficult issues for this technology is the determination of which trade specifies these systems — architectural, electrical, or mechanical; covered in previous posts.   Instead, most of our time will be spent getting IEEE consensus products in step with it, specifically ANSI/IEEE 515 and IEEE 844/CSA 293.

Comments on the Second Draft of the 2026 NEC will be received until April 18th.

454c656374726f746563686e6f6c6f6779

We collaborate with the IEEE Education & Healthcare Facility Committee which meets online 4 times per month in European and American time zones.  Since a great deal of the technical basis for the NEC originates with the IEEE we will also collaborate with IEEE Standards Coordinating Committee 18 whose members are charged by the IEEE Standards Association to coordinate NFPA and IEEE consensus products.

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.

Healthcare Facilities Code

“The Doctor”  1891 Sir Luke Fildes

The NFPA 99 Healthcare Facilities Code committee develops a distinct consensus document (i.e. “regulatory product”) that is distinct from National Electrical Code Article 517; though there are overlaps and gaps that are the natural consequence of changing technology and regulations.  It is worthwhile reviewing the scope of each committee:

NFPA 99 Scope: This Committee shall have primary responsibility for documents that contain criteria for safeguarding patients and health care personnel in the delivery of health care services within health care facilities: a) from fire, explosion, electrical, and related hazards resulting either from the use of anesthetic agents, medical gas equipment, electrical apparatus, and high frequency electricity, or from internal or external incidents that disrupt normal patient care; b) from fire and explosion hazards; c) in connection with the use of hyperbaric and hypobaric facilities for medical purposes; d) through performance, maintenance and testing criteria for electrical systems, both normal and essential; and e) through performance, maintenance and testing, and installation criteria: (1) for vacuum systems for medical or surgical purposes, and (2) for medical gas systems; and f) through performance, maintenance and testing of plumbing, heating, cooling , and ventilating in health care facilities.

NFPA 70 Article 517 Scope:  The provisions of this article shall apply to electrical construction and installation criteria in healthcare facilities that provide services to human beings.  The requirements in Parts II and III not only apply to single-function buildings but are also intended to be individually applied to their respective forms of occupancy within a multi-function building (e.g. a doctor’s examining room located within a limited care facility would be required to meet the provisions of 517.10)   Informational Note: For information concerning performance, maintenance, and testing criteria, refer to the appropriate health care facilities documents.

In short, NFPA 70 Article 517 is intended to focus only on electrical safety issues though electrotechnology complexity and integration in healthcare settings (security, telecommunications, wireless medical devices, fire safety, environmental air control, etc.) usually results in conceptual overlap with other regulatory products such as NFPA 101 (Life Safety Code) and the International Building Code.

Several issues were recently debated by the Article 517 technical committee during the 2023 National Electrical Code Second Draft meetings

  • The conditions under which reconditioned electrical equipment be installed in healthcare settings; contingent on listing and re-certification specifics.
  • Relaxation of the design rules for feeder and branch circuit sizing through the application of demand factors.
  • Application of ground fault circuit interrupters.
  • “Rightsizing” feeder and branch circuit power chains (Demand factors in Section 517.22)
  • Patient care space categories
  • Independence of power sources (517.30)

There are, of course, many others, not the least of which involves emergency management.  For over 20 years our concern has been for the interdependency of water and electrical power supply to university hospitals given that many of them are part of district energy systems.

We need to “touch” this code at least once a month because of its interdependence on other consensus products by other standards developing organizations.  To do this we refer NFPA 99 standards action to the IEEE Education & Healthcare Facilities Committee which meets online four times monthly in European and American time zones.

Guide to Premises Security

School of Aristotle | Gustav Spangenberg

Managing capital‐intensive campus infrastructure embedded within a politically sensitive community presents challenges not present in private industry real assets. Differences in everything from department culture to annual facility use patterns mean that facility managers cannot implement the same safety approaches in all buildings.  Approaches must be scaled and tailored to the occupancy type and informed by the interconnectedness and the specifics of a given facility.  Accordingly, the original University of Michigan standards advocacy enterprise (see ABOUT) began following the development of safety concepts in both NFPA 730 and NFPA 731 with the release of the 2008 Edition.   Thereafter, it collaborated with trade associations and subject matter experts from other universities (notably Georgetown University and Evergreen State University) to advocate user-interest concepts in the 2011 revisions.

Since 2008, campus security issues have only become more complex technically; across an expanding minefield of sensitivities.   Since 2008 we have observed the emergence of about one-hundred new consensus products being developed by the same number of new trade associations and producers presenting campus security solutions.

NFPA 730 Guide to Premise Security is a consensus document that describes construction, protection, occupancy features, and practices intended to reduce security vulnerabilities to life and property.  Related document — NFPA 731 Standard for the Installation of Electronic Premises Security Systems covers the application, location, installation, performance, testing, and maintenance of electronic premises security systems and their components.   The first is a performance document; the second a prescriptive document for the construction, operation and maintenance of electrotechnologies that support premise security.

Public consultation on the 2023 revision closed January 5, 2022 however the NITMAM process permits additional comment at the 2023 NFPA Annual meeting in Las Vegas in June 2023.

The 2026 Edition is now open for public input until January 4, 2024.

Public Comment on the First Draft of the 2026 Edition will be received until January 3, 2025

As always, we encourage direct participation by user-interests supporting the education facility industry.   You may do so by CLICKING HERE.

It is never a bad idea to key in comments on your own but if you would like some insight into our advocacy vectors since 2008 you are welcomed to click in our periodic Risk and Public Safety colloquia during which time we pick through technical, policy and enforcement specifics.   We have been hammering on Chapters 11 and 12, Education and Healthcare Facilities, respectively; for five cycles.   See our CALENDAR for the next online meeting; open to everyone.
