2023 National Electrical Code | Current Issues and Recent Research
August 5, 2021
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:
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 Comment Report Panel 12
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

Force Majeure
In his books, The Black Swan and Antifragile, Nassim Nicholas Taleb observes that freak disasters—rare, high-impact events—are unpredictable and often underestimated due to their low probability. He calls these “Black Swan” events, characterized by their extreme rarity, severe consequences, and retrospective predictability. Taleb argues that people and systems are overly reliant on normalcy and linear models, ignoring the potential for such outliers.
These disasters expose the fragility of complex systems, like financial markets or infrastructure, which are unprepared for extreme shocks. In Antifragile, he contrasts fragile systems with antifragile ones, which thrive under stress. Taleb emphasizes that freak disasters are not anomalies but inevitable in a complex world, urging risk management that accounts for uncertainty rather than predictability. He critiques overconfidence in forecasting and advocates for building resilience to mitigate the devastating effects of these unpredictable events.
We cover this ground, more than tangentially, in our activism in disaster management standards setting. Our coverage of this topic dates back to 1993 which the links below should reveal. We will expand upon this topic as more information is derived from this past week’s events in Kerr County Texas.

Intellectual Property
It is impossible to overestimate the sensitivity of this topic but poke at it, we will. At the moment, the less written here; the better. Much of this domain is outside our wheelhouse; though it has settled on a few first principles regarding patents, trademarks and copyrights relevant to the user-interest we describe in our ABOUT.
Many large research universities have a watchdog guarding its intellectual property and trying to generate income from it, and; of course, for branding. We will dwell on salient characteristics of the intellectual property domain with which we reckon daily — highlighting the market actors and the standards they have agreed upon.
Additionally, technical standards developers are generally protected by copyright law, as the standards they create are typically considered original works of authorship that are subject to copyright protection. In the United States, the Copyright Act of 1976 provides copyright protection for original works of authorship, which includes technical standards. This means that the developers of technical standards have the exclusive right to reproduce, distribute, and create derivative works based on their standards, and others must obtain permission or a license to use or reproduce the standards.
Some technical standards may be subject to certain exemptions or limitations under copyright law. In the United States, there is a doctrine called “fair use” that allows for limited use of copyrighted works for purposes such as criticism, comment, news reporting, teaching, scholarship, or research, without the need for permission or a license from the copyright owner. Almost everything we do at Standards Michigan falls under the fair use doctrine. This is why we have no search feature and most pages are protected. If we err in this; let us know.

Vad är en standard? Syftet med standarder är att skapa enhetliga och transparenta rutiner som vi kan enas kring. Det ligger ju i allas intresse att höja kvaliteten, undvika missförstånd och slippa uppfinna hjulet på nytt varje gång. https://t.co/zKhgPXPdpW pic.twitter.com/oKejdKSm47

The choice of red, white, and blue in national flags often carries historical, cultural, and political significance. Here are some reasons why various nations have chosen these colors:
- Historical Connections:
- United States: The colors were chosen for their flag in 1777 and have been interpreted to symbolize valor (red), purity (white), and justice (blue). The colors were influenced by the British Union Jack.
- France: The Tricolour flag adopted during the French Revolution represents liberty (blue), equality (white), and fraternity (red).
- United Kingdom: The Union Jack combines elements from the flags of England (red and white), Scotland (blue and white), and Ireland (red and white).
- Cultural and Political Significance:
- Russia: The flag’s colors were adopted from the Dutch flag, symbolizing pan-Slavism (red for bravery, blue for faithfulness, and white for honesty).
- Netherlands: The Dutch flag’s colors (originally derived from the Prince’s Flag) have historical roots, symbolizing the struggle for independence and liberty.
- Czech Republic and Slovakia: Both countries use red, white, and blue to represent their Slavic heritage.
- Influence and Inspiration:
- Chile, Costa Rica, and Panama: These countries were influenced by the colors and symbolism of other flags (e.g., the French and American flags) during their independence movements.
- Australia and New Zealand: Both countries incorporate the Union Jack in their flags, reflecting their colonial history with the United Kingdom.
- Symbolism:
- Croatia, Serbia, and Slovenia: The colors are traditional pan-Slavic colors, representing freedom and national unity.
- Iceland and Norway: The colors reflect their historical and cultural ties to other Scandinavian countries.
The exact reasons can vary, but often the colors reflect a mix of historical alliances, cultural heritage, and political ideals.
