The 2020 National Electrical Code (NEC) contains significant revisions to Article 625 Electric Vehicle Power Transfer Systems.  Free access to this information is linked below:

2023 National Electrical Code

2020 National Electrical Code

You will need to set up a (free) account to view Article 625 or you may join our colloquium today.

Public input for the 2023 Edition of the NEC has already been received.  The work of the assigned committee — Code Making Panel 12 — is linked below:

NFPA 70_A2022_NEC_P12_FD_PIReport_rev

Mighty spirited debate.   Wireless charging from in-ground facilities employing magnetic resonance are noteworthy.  Other Relevant Articles:

  • Article 240: Overcurrent Protection: This article includes requirements for overcurrent protection devices that could be relevant for EV charging systems.
  • Article 210: Branch Circuits: General requirements for branch circuits, which can include circuits dedicated to EVSE.
  • Article 220: Load Calculations: Guidelines for calculating the electrical load for EVSE installations.
  • Article 230: Services: General requirements for electrical service installations, which can be relevant for EVSE.
  • Article 250: Grounding and Bonding: Requirements for grounding and bonding, which are critical for safety in EVSE installations.

 

Technical committees meet November – January to respond.   In the intervening time it is helpful  break down the ideas that were in play last cycle.  The links below provide the access point:

Public Input Report Panel 12

Public Comment Report Panel 12

Panel 12 Final Ballot

We find a fair amount of administrative and harmonization action; fairly common in any revision cycle.   We have taken an interest in a few specific concepts that track in academic research construction industry literature:

  • Correlation with Underwriters Laboratory product standards
  • Bi-Directional Charging & Demand Response
  • Connection to interactive power sources

As a wiring safety installation code — with a large installer and inspection constituency — the NEC is usually the starting point for designing the power chain to electric vehicles.   There is close coupling between the NEC and product conformance organizations identified by NIST as Nationally Recognized Testing Laboratories; the subject of a separate post.

After the First Draft is released June 28th public comment is receivable until August 19th.

We typically do not duplicate the work of the 10’s of thousands of National Electrical Code instructors who will be fanning out across the nation to host training sessions for electrical professionals whose license requires mandatory continuing education.  That space has been a crowded space for decades.   Instead we co-host “transcript reading” sessions with the IEEE Education & Healthcare Facilities Committee to sort through specifics of the 2020 NEC and to develop some of the ideas that ran through 2020 proposals but did not make it to final ballot and which we are likely to see on the docket of the 2023 NEC revision.   That committee meets online 4 times monthly.  We also include Article 625 on the standing agenda of our Mobility colloquium; open to everyone.   See our CALENDAR for the next online meeting

Technical Committee 82 of the International Electrotechnical Commission is charged with preparing international standards for the full length of the solar energy power chain  The span of the power chain includes the light input, the cell itself, and the fittings and accessories to the end use (utilization) equipment.

Strategic Business Plan of IEC Technical Committee 82

The United States is the Global Secretariat for TC 82 through the US National Committee of the International Electrotechnical Commission (USNA/IEC) administered by the American National Standards Institute(ANSI).  Standards Michigan is a long-standing member of ANSI since our “standards journey” began at the University of Michigan in 1993.

The USNA/IEC and participates in its standards development processes; typically collaborating with global research and application engineers in the IEEE Industrial Applications Society and the IEEE Power and Energy Society.   To advance its agenda for lower #TotalCostofOwnership for US real asset executives and facility managers Standards Michigan also collaborates closely with subject matter experts who contribute to, and draw from, the knowledge base in the IEEE Education and Healthcare Facilities Committee (E&H).

The IEC permits public commenting on its draft standards; though you will need to establish login credentials:

IEC Public Commenting

Your comments will be reviewed by the IEC National Committee of the country you live in, which can decide to propose them as national input for the final draft of the IEC International Standard.  This approach makes it easier for individual nations to participate in IEC standards development processes because the resources that national standards bodies need to administer participation resides in Geneva and is managed there.

We collaborate with the IEEE Education & Healthcare Facilities Committee which has its own platform to tracking commenting opportunities:

IEEE E&H/USNC/IEC Workspace

As of this posting, no interoperability redlines have been released for public consultation.   In large measure, IEC titles contribute to a level playing field among multi-national electrical equipment manufacturers so we should not be surprised that there are no redlines to review.   When they are released we place them on the agenda of the IEEE E&H Committee which meets 4 times monthly in European and American time zones.

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:

We will pick through specifics in the transcripts of Code Making Panels 10 and 18.

Electrical building — World Columbian Exposition, Chicago, Illinois 1892

The International Code Council bibliography of electrical safety practice incorporates titles published by the National Fire Protection Association which reference electrical safety science titles published by the Institute of Electrical and Electronic Engineers.  The relevant section of the International Building Code is therefore relatively short:

2021 International Building Code: Chapter 27 Electrical

Note that Chapter 27 provides more guidance on managing the hazards created when electricity is absent*.  Since the National Electrical Code is informed by a fire safety building premise wiring culture; absence of electricity is not as great a hazard as when building wiring systems are energized.  (“So they say” — Mike Anthony, who thinks quite otherwise.)

Although we collaborate most closely with the IEEE Education & Healthcare Facilities Committee (four times monthly in Europe and the Americas) we e encourage our colleagues in education communities everywhere to participate directly in the ICC Code Development process.   CLICK HERE to set up an account.

It is enlightening — and a time saver — to unpack the transcripts of previous revisions of codes and standards to see what concepts were presented, what got discussed; what passed and what failed.  We provide links to a few previous posts that track recent action in the ICC suite relevant to electrotechnologies:

Electric Vehicle Charging

Entertainment Occupancies

K-TAG Matrix for Healthcare Facilities

International Energy Conservation Code

The ICC suite of consensus products are relevant to almost all of our work; everyday.   See our CALENDAR that reflects our Syllabus.  Today we deal with electrical safety concepts because technical committees are meeting from November to January to write the 2023 National Electrical Code.  CLICK HERE to follow the action in more detail.

* The original University of Michigan advocacy enterprise began pounding on National Electrical Code committees to install more power reliability concepts in the 2002 Edition with only modest success.  Standards Michigan has since collaborated with the IEEE Education & Healthcare Facilities Committee to drive “absence-of-power-as-a-hazard” into the National Electrical Code; the 2023 now open for public consultation.

N.B.

Assuming building interior fire safety issues can be managed, one way of getting more electric vehicle charging stations built around campus is to install requirements into the building code — thereby putting the construction cost, operation, maintenance and risk upon real-asset Developers and Owners. Code change submittals for the Group A tranche of titles will be received until January 8, 2024.

We use the term “backup” power system to convey the complexity of electrical power sources when the primary source is not used; either as a scheduled or an unscheduled event.   Best practice literature in this domain has been relatively stable, even though challenged by newer primary source of power technologies.   We are running our daily colloquium in parallel with the recurring 4 times monthly meetings of the IEEE Education & Healthcare Facilities Committee.   You are welcomed to join us with the login credentials at the upper right of our home page.
