Pool, Fountain, Agriculture & Water Infrastructure Electrical Safety

2026 National Electrical Code Workspace

“The Bathing Pool” / Hubert Robert (French, 1733–1808) / Gift of J.P. Morgan

Education communities have significant assets tied up in swimming pools, immersion pools, fountains, hydro-therapy installations (in hospitals and athletic training facilities) and flood control facilities (in congested, non-permeable parts of urban campuses) we have been keeping an eye on leading practice discovery for these installations in the 2020 National Electrical Code.

With electrical safety — i.e. shock protection — as the focus of this post*, the relevant parts of the 2020 NEC reside in Articles 680 and 682 are described below:

Article 680 applies to the construction and installation of electrical wiring for, and equipment in or adjacent all swimming, wading, therapeutic and decorative pools, fountains, hot tubs, spas and hydromassage bathtubs, whether permanently installed or storable, and to metallic auxiliary equipment, such as pumps, filters, and similar equipment.  The term body of water used throughout Part I applies to all bodies of water covered in this scope unless otherwise amended.

Article 682 applies to the installation of electrical wiring for, and the equipment in and adjacent to, natural or artificially made bodies of water not covered by other articles in the NEC, such as, but not limited to aeration ponds, fish farm ponds, storm retention basins, treatment ponds and irrigation (channel facilities.   Water depths may vary seasonally or be controlled.

When the 2020 NEC is released there will be hundreds (more like thousands) of experts who make their living on each NEC revision fanning out across the globe able and ready to interpret, advise and train.  We are not primarily a code training enterprise but we do get down into the weeds of electrical safety technical discussion where leading practice discovery discussion is recorded:

2020 NEC Article 680-682 Public Input | Pages 240 – 501

2020 NEC Articles 680-682 First Draft Report | Page 59 – 152

2020 NEC Articles 680-682 Public Comment Report

2020 NEC Articles 680-682 Second Draft Final Ballot

Transcripts superseded.  We refer to the 2026 Workspace linked at the top of this page.

We find interest in corrosion control, water bottle fill stations, water heating technologies, LED illumination as well as the usual editorial, correlation and concepts movement between articles.  From these transcripts it should also be plain that grounding and bonding practice, GFCI protection, luminaire location and wiring, corrosion management continue to be of primary interest in electrical safety assurance.   Related safety concepts appear in NFPA 70B and NFPA 70E.   Anything having to do with water; or the areas around water, are regions of elevated risk.

We are happy to discuss electrical safety standards any day at 11 AM Eastern time and host a monthly breakout teleconference dedicated to Electrical Power Safety in education facilities.  See our CALENDAR for the next online meeting.  We also collaborate closely with the IEEE Education & Healthcare Facilities Committee which meets online four times monthly in European and American time zones.

Geoffrey Hinton & Joel Hellermark

This conversation was recorded in April 2024 at the Royal Institute of Great Britain in London. An edited version was premiered at Sana AI Summit on May 15 2024 in Stockholm, Sweden.

Geoffrey Hinton has been called “the godfather of AI” and is considered one of the most prominent thought leaders on the emergence of artificial intelligence. He has served as a faculty member at Carnegie-Mellon and a fellow of the Canadian Institute for Advanced Research. He is now Emeritus Professor at the University of Toronto. In 2023, Geoffrey left his position at Google so that he could speak freely about AI’s impact on humankind.

Fountains

“Temple, Fountain and Cave in Sezincote Park” | Thomas Daniell (1819) | Yale Center for British Art

From time to time we break from our interest in lowering the cost of our “cities-within-cities” to enjoy the work of our colleagues responsible for seasonal ambience and public art.  We have a dedicated post that celebrates the accomplishments of our gardeners and horticultural staff.   Today we dedicate a post to campus fountains–a focal point for gathering and a place for personal reflection for which there is no price.

Alas, we find a quickening of standards developing organizations growing their footprint in the spaces around buildings now.  They used to confine the scopes of their standardization enterprises to the building envelope.  That day will soon be behind us as an energized cadre of water rights social justice workers, public safety, sustainability and energy conservation professionals descend upon campus fountains with prescriptive requirements for evaporation rates, bromine concentrations, training, certification and inspections.  In other words regulators and conformity functionaries will outnumber benefactors and fountain designers 1 million to 1.

We will deal with all that when the day comes.  For the moment, let’s just enjoy them.

We are happy to walk you through the relevant structural, water safety, plumbing and electrical issues any day at 11 AM EST during our daily standing online teleconferences.   Click on any image for author attribution, photo credit or other information.

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:

  1. 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).
  2. 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.
  3. 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.
  4. 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.

 

Summer Sport

Athena with Hermes, God of Sport

Today we slice horizontally through the multitude of technical and policy silos applicable to seasonal recreational and competitive sport activity.  For the 2024 Paris Olympics we will focus on the infrastructure supporting the events listed below:

Beach Volleyball

Equestrian

Rowing

Sailing

Swimming & Diving

Track & Field

We limit our examination to the conformance catalogs of ANSI. ASHRAE. ASTM, AWWA, ICC, IEEE, IES, NFPA, NSF International, and UL.

We deal with the catalogs of CSA, DNV GL  ISO, IEC, SGS, TIC and TÜV in a separate, international session.
