AWWA COMMENT PERIOD ON AWWA G480, Water Conservation and Efficiency Program Operation and Management Closes June 23

Harvard University Art Museum | In the Sierras, Lake Tahoe | Albert Bierstadt

The American Water Works Association is one of the first names in accredited standards developers that administer leading practice discovery in backflow prevention consensus documents; usually referenced in local and state building codes; and also in education facility design guidelines and construction specifications.

The original University of Michigan standards enterprise gave highest priority to backflow standards because of their central importance of backflow management to education communities; especially large research universities nested within a municipal water system.  Backflow prevention; an unseen technology that assures a safe drinking water supply by keeping water running in one direction by maintaining pressure differences.  Analogous to the way we want electrical current to run in one direction, failure of backflow prevention technology poses a near-instantaneous health risk for the contamination of potable water supplies with foul water.  In the most obvious case, a toilet flush cistern and its water supply must be isolated from the toilet bowl.  In a less obvious case, but at greater scale, a damaged backflow prevention technology at a university research building can contaminate an host-community potable water supply.

There are other ANSI accredited standards developers in the backflow prevention technology space — the International Code Council, the IAPMO Group and ASSE International — for example.

Restore NESC Cross-Reference to the Front End of the NEC

Federal Power Act of 1920  Ω  Public Utility Holding Company Act of 1935.

IEEE Education & Healthcare Facilities Committee Ω Current Issues and Recent Research

Representative Sample of Merchant Utility Interconnection Requirements for Customers

2023 National Electrical Code Article 490 Bibliography

Ahead of the April close date for comments on the Second Draft of the 2026 revision of the NEC we examine thought trends on the following:

  1. How does “high voltage” differ among electrotechnology professionals?  Signaling and control systems workers have a much lower criteria than a merchant utility lineman than a campus bulk distribution engineer.  In other words, “high voltage” is generally understood in practice and essential for worker safety.  Labeling counts.
  2. What is the origin of the apparent “confusion’ about high voltage in the IEEE, IEC, NFPA and TIA electrical safety catalogs?  Is the distinction functionally acceptable — i.e. a term of art understood well enough in practice?
  3. How can the 2026 NEC be improved for engineers, electricians and inspectors?  There has been some considerable re-organization of low, medium and high voltage concepts in the 2023.  It usually takes at least two NEC revision cycles for workable code to stabilize.  Since education communities purchase and distribute higher voltage power on large campuses; how can power purchasing and customer distribution system best practice be improved?

This is plenty to talk about.   Join us today at 15:00/16:00 UTC with the login credentials at the upper right of our home page.

IEC technical committees and subcommittees Ω SMB Tabulation

IEC and ITU offices | Geneva

Much economic activity in the global standards system involves products — not interoperability standards. Getting everything to work together — safely, cost effectively and simpler — is our raison d’etre.  

Manufacturers, testing laboratories, conformance authorities (whom we call vertical incumbents) are able to finance the cost of their advocacy — salaries, travel, lobbying, administration — into the cost of the product they sell to the end user (in our cases, estate managers in educational settlements).  To present products — most of which involve direct contact with a consumer — at a point of sale it must have a product certification label.  Not so with systems.  System certification requirements, if any, may originate in local public safety requirements; sometimes reaching into the occupational safety domain.

Our readings of the intent of this technical committee is to discover and promulgate best practice for “systems of products” — i.e. ideally interoperability characteristics throughout the full span of the system life cycle.

To quote Thomas Sowell:

“There are no absolute solutions to human problems, there are only tradeoffs.”  

Many problems have no solutions, only trade-offs in matters of degree.  We explain our lament over wicked problems in our About.

ARCHIVE

The United States National Committee of  the International Electrotechnical Commission (USNA/IEC) seeks participants and an ANSI Technical Advisory Group (US TAG) Administrator for an IEC subcommittee (Multi-Agent System) developing standards for power system network management.   From the project prospectus:

Standardization in the field of network management in interconnected electric power systems with different time horizons including design, planning, market integration, operation and control.  SC 8C covers issues such as resilience, reliability, security, stability in transmission-level networks (generally with voltage 100kV or above) and also the impact of distribution level resources on the interconnected power system, e.g. conventional or aggregated Demand Side Resources (DSR) procured from markets.

SC 8C develops normative deliverables/guidelines/technical reports such as:

– Terms and definitions in area of network management,
– Guidelines for network design, planning, operation, control, and market integration
– Contingency criteria, classification, countermeasures, and controller response, as a basis of technical requirements for reliability, adequacy, security, stability and resilience analysis,
– Functional and technical requirements for network operation management systems, stability control systems, etc.
– Technical profiling of reserve products from DSRs for effective market integration.
– Technical requirements of wide-area operation, such as balancing reserve sharing, emergency power wheeling.

Individuals who are interested in becoming a participant or the TAG Administrator for SC 8C: Network Management are invited to contact Adelana Gladstein at agladstein@ansi.org as soon as possible.

This opportunity, dealing with the system aspects of electrical energy supply (IEC TC 8), should at least interest electrical engineering research faculty and students involved in power security issues.   Participation would not only provide students with a front-row seat in power system integration but faculty can collaborate and compete (for research money) from the platform TC 8 administers.  We will refer it to the IEEE Education & Healthcare Facilities Committee which meets online 4 times monthly in European and American time zones.

Today we will also cut through these transcripts:

2026 Code Panel 6 Public Input Report

2026 Code Panel 6 Public Comment Report

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.

First Quarter 2026 Earnings Release | May 5, 2026

 

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-8: Reconditioned equipment

CMP-9: Reconditioned equipment

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
