Readings: The “30-30” Rule for Outdoor Athletic Events Lightning Hazard
Thunderstorm | Shelter (Building: 30/30 Rule)
The standards for delaying outdoor sports due to lightning are typically set by governing bodies such as sports leagues, associations, or organizations, as well as local weather authorities. These standards may vary depending on the specific sport, location, and level of play. However, some common guidelines for delaying outdoor sports due to lightning include:
- Lightning Detection Systems: Many sports facilities are equipped with lightning detection systems that can track lightning activity in the area. These systems use sensors to detect lightning strikes and provide real-time information on the proximity and severity of the lightning threat. When lightning is detected within a certain radius of the sports facility, it can trigger a delay or suspension of outdoor sports activities.
- Lightning Distance and Time Rules: A common rule of thumb used in outdoor sports is the “30-30” rule, which states that if the time between seeing lightning and hearing thunder is less than 30 seconds, outdoor activities should be suspended, and participants should seek shelter. The idea is that lightning can strike even when it is not raining, and thunder can indicate the proximity of lightning. Once the thunder is heard within 30 seconds of seeing lightning, the delay or suspension should be implemented.
- Local Weather Authority Guidelines: Local weather authorities, such as the National Weather Service in the United States, may issue severe weather warnings that include lightning information. Sports organizations may follow these guidelines and suspend outdoor sports activities when severe weather warnings, including lightning, are issued for the area.
- Sports-Specific Guidelines: Some sports may have specific guidelines for lightning delays or suspensions. For example, golf often follows a “Play Suspended” policy, where play is halted immediately when a siren or horn is sounded, and players are required to leave the course and seek shelter. Other sports may have specific rules regarding how long a delay should last, how players should be informed, and when play can resume.
It’s important to note that safety should always be the top priority when it comes to lightning and outdoor sports. Following established guidelines and seeking shelter when lightning is detected or severe weather warnings are issued can help protect participants from the dangers of lightning strikes.
Noteworthy: NFPA titles such as NFPA 780 and NFPA 70 Article 242 deal largely with wiring safety, informed by assuring a low-resistance path to earth (ground)
There are various lightning detection and monitoring devices available on the market that can help you stay safe during thunderstorms. Some of these devices can track the distance of lightning strikes and alert you when lightning is detected within a certain radius of your location. Some devices can also provide real-time updates on lightning strikes in your area, allowing you to make informed decisions about when to seek shelter.
Examples of such devices include personal lightning detectors, lightning alert systems, and weather stations that have lightning detection capabilities. It is important to note that these devices should not be solely relied upon for lightning safety and should be used in conjunction with other safety measures, such as seeking shelter indoors and avoiding open areas during thunderstorms.
Electric Vehicle Charging Stations
Edison electric vehicle | National Park Service, US Department of the Interior
Electrical power engineers know that it is unwise to imagine a totally electric mobility system in the mind’s eye of vertical incumbents, policy makers and trendsniffers. That does not mean that, as licensed professionals, we cannot positively respond to the demand for more electric mobility on campuses and within school districts.
Today we run through current codes, standards and guides to make that power supply chain safe and sustainable. Use the login credentials at the upper right of our home page.
In addition to the “NEC canonicals” — listing, coupler heights, disconnect, grounding, voltage, ampacity and overcurrent protection that would likely be applied in a fleet enclosure, more specific passages are relevant when the charging stations are widely dispersed in exterior locations:
Article 225 Outside branch circuits and feeders
Article 625 Electric Vehicle Power Transfer System
We will deal with cable management, IEC 61851 titles, Level 1 & 2 equipment, load management, placement of charging stations at motor fuel dispensing installations and wireless charging systems in a separate session.
NECA 413 Standard For Installing And Maintaining Electric Vehicle Supply Equipment
National Electric Vehicle Infrastructure Standards and Requirements
Much like designing and building campus outdoor lighting systems, there are more site-related issues to be reckoned with. For example:
- Charging infrastructure: One of the biggest space usage problems with EVs is the need for charging infrastructure. EV owners require access to charging stations in order to recharge their vehicles, and these charging stations can take up valuable space in public areas or campus parking structures that may require additional fire protection systems (that also require upgraded electrotechnologies.
- Battery storage: Another space usage issue with EVs is the need for battery storage. EV batteries are large and heavy, and require adequate storage space for safe and secure disposal at the end of their life cycle.
- Vehicle size: Many EVs are larger and heavier than traditional gasoline-powered vehicles, which can create space usage problems in urban areas where parking and road space is limited.
- Recycling infrastructure: As EVs become more common, the need for specialized recycling infrastructure for EV components, including batteries, motors, and electronics, is likely to increase. These facilities require additional space and resources to safely and efficiently process and recycle these components.
Addressing these space usage problems will require a combination of policy interventions, technological innovations, and public awareness campaigns to promote the benefits and potential of EVs while minimizing their environmental impact and spatial footprint.

Management of Assets in Power Systems
From Case Studies to Standards
- Has anyone built this? (We hope so)
- Has anyone measured it?
- Has it failed anywhere?
- Can it be inspected; when an how often?
- Can it be maintained and can we train people to maintain it?
- Is the additional complexity justified? (Keep in mind Standards Michigan objective: Safer – Simpler – Lower Cost – Longer Lasting
- Can we write enforceable Code language that will not limit innovation?

The Japanese Standards Association is the Global Secretariat for a standardization project devoted to the discovery and promulgation of common methods and guidelines for coordinated lifetime management of network assets in power systems to support good asset management. In addition, this may include the development of new methods and guidelines required to keep pace with development of electrotechnologies excluding generation assets; covered by other IEC standards.
There has, and will continue to be significant investment in electricity assets which will require ongoing management to realise value for the organizations. In the last 5 years, there has been USD 718 billion investment for electricity, spending on electricity networks and storage continued, reaching an all-time high of USD 277 billion in 2016. In the United States (17% of the total) and Europe (13%), a growing share is going to the replacement of ageing transmission and distribution assets. A more fully dimensioned backgrounder on the business environment that drives the market for this title is available in the link below:

It is early in this project’s lifecycle; far too early to find it referenced in public safety and energy laws in the United States where it would affect #TotalCostofOwnership. Where we should, we follow the lead of the USNC/IEC for the United States, while still mindful that many of our IEEE colleagues follow the lead of their own national standards body.
Because this project fills an obvious gap in good practice literature we maintain this project on our 4 times monthly electrotechnology colloquium that we co-host with the IEEE Education & Healthcare Facilities Committee. See our CALENDAR for the next online meeting; open to everyone.

FEMA National Risk Index: Lightning
_-_Benjamin_Franklin_Drawing_Electricity_from_the_Sky_-_Google_Art_Project.jpg)
“Benjamin Franklin Drawing Electricity from the Sky” 1816 Benjamin West
Benjamin Franklin conducted his famous experiment with lightning on June 10, 1752.
He used a kite and a key to demonstrate that lightning was a form of electricity.
This experiment marked an important milestone in understanding the nature of electricity
and laid the foundation for the development of lightning rods and other lightning protection systems.
Seasonal extreme weather patterns in the United States, resulting in damages to education facilities and delays in outdoor athletic events — track meets; lacrosse games, swimming pool closures and the like — inspire a revisit of the relevant standards for the systems that contribute to safety from injury and physical damage to buildings: NFPA 780 Standard for the Installation of Lightning Protection Systems
To paraphrase the NFPA 780 prospectus:
- This document shall cover traditional lightning protection system installation requirements for the following:
(1) Ordinary structures
(2) Miscellaneous structures and special occupancies
(3) Heavy-duty stacks
(4) Structures containing flammable vapors, flammable gases, or liquids with flammable vapors
(5) Structures housing explosive materials
(6) Wind turbines
(7) Watercraft
(8) Airfield lighting circuits
(9) Solar arrays - This document shall address lightning protection of the structure but not the equipment or installation requirements for electric generating, transmission, and distribution systems except as given in Chapter 9 and Chapter 12.
(Electric generating facilities whose primary purpose is to generate electric power are excluded from this standard with regard to generation, transmission, and distribution of power. Most electrical utilities have standards covering the protection of their facilities and equipment. Installations not directly related to those areas and structures housing such installations can be protected against lightning by the provisions of this standard.)
- This document shall not cover lightning protection system installation requirements for early streamer emission systems or charge dissipation systems.
“Down conductors” must be at least #2 AWG copper (0 AWG aluminum) for Class I materials in structures less than 75-ft in height
“Down conductors: must be at least 00 AWG copper (0000 AWG aluminum) for Class II Materials in structures greater than 75-ft in height.
Related grounding and bonding requirements appears in Chapters 2 and Chapter 3 of NFPA 70 National Electrical Code. This standard does not establish evacuation criteria.

The current edition is dated 2023 and, from the transcripts, you can observe concern about solar power and early emission streamer technologies tracking through the committee decision making. Education communities have significant activity in wide-open spaces; hence our attention to technical specifics.
Public input on the 2026 revision is receivable until 1 June 2023.
We always encourage our colleagues to key in their own ideas into the NFPA public input facility (CLICK HERE). We maintain NFPA 780 on our Power colloquia which collaborates with IEEE four times monthly in European and American time zones. See our CALENDAR for the next online meeting; open to everyone.

Installing lightning protection system for your facility in 3 Steps (Surge Protection)
IEEE Education & Healthcare Facility Electrotechnology
Readings: The “30-30” Rule for Outdoor Athletic Events Lightning Hazard
Churches and chapels are more susceptible to lightning damage due to their height and design. Consider:
Height: Taller structures are more likely to be struck by lightning because they are closer to the cloud base where lightning originates.
Location: If a church or chapel is situated in an area with frequent thunderstorms, it will have a higher likelihood of being struck by lightning.
Construction Materials: The materials used in the construction of the building can affect its vulnerability. Metal structures, for instance, can conduct lightning strikes more readily than non-metallic materials.
Proximity to Other Structures: If the church or chapel is located near other taller structures like trees, utility poles, or buildings, it could increase the chances of lightning seeking a path through these objects before reaching the building.
Lightning Protection Systems: Installing lightning rods and other lightning protection systems can help to divert lightning strikes away from the structure, reducing the risk of damage.
Maintenance: Regular maintenance of lightning protection systems is essential to ensure their effectiveness. Neglecting maintenance could result in increased susceptibility to lightning damage.
Historical Significance: Older buildings might lack modern lightning protection systems, making them more vulnerable to lightning strikes.
The risk can be mitigated by proper design, installation of lightning protection systems, and regular maintenance.

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

Joint Use of Electric Power Transmission & Distribution Facilities and Equipment
Telephone, telegraph, and power lines over the streets of New York City 1888
Guide for the Joint Use of Electric Power Transmission & Distribution Facilities and Equipment
Abstract: This guide identifies the mechanisms and an analytic approach for developing consistent rules, agreements, and/or methodologies for the evaluation and inter-entity cooperation managing pole attachments on utility infrastructure that can contain both electric supply as well as communications wireline and wireless facilities.
The common safety codes and accepted good industry practices for joint use are referenced, including items such as clearances and strength/loading requirements, appropriate work rules during installation, maintenance and restoration, and general guidelines. The considerations within this guide can be used to help perform a detailed assessment of attachment installations where communications antennas and related wireline and wireless equipment are to be co-located on joint use structures.
Scope: This guide provides recommendations for the development of consistent guides, agreements, and/or methodologies for the evaluation and inter-company cooperation on managing pole attachments on Electric Utility infrastructure.
Purpose: The Joint Use Guide documents consistent approaches, methodologies and rules for the sharing and co-location of equipment with electric Transmission & Distribution (T&D) facilities for communications such as antennae and/or cable. With the emergence of new communications networks and emerging technologies which depend on widely distributed communications {e.g. 5G and Internet of Things ( IoT)}, the needs of vertical real-estate for use in communications is expected to dramatically increase in the coming years. While electric T&D facilities provide an excellent platform to help meet these needs, there are significant safety and reliability issues associated with their use.

Federal Energy Regulatory Commission: Electrical Resource Adequacy
NARUC Position on NFPA (NEC) and IEEE (NESC) Harmonization
The standard of care for electrical safety at high and low voltage is set by both the NEC and the NESC. There are gaps, however (or, at best “gray areas”) — the result of two technical cultures: utility power culture and building fire safety culture. There is also tradition. Local system conditions and local adaptation of regulations vary. Where there is a gap; the more rigorous requirement should govern safety of the public and workers.
The 2023 National Electrical Safety Code (NESC)– an IEEE title often mistaken for NFPA’s National Electrical Code (NEC) — was released for public use about six months ago; its normal 5-year revision cycle interrupted by the circumstances of the pandemic. Compared with the copy cost of the NEC, the NESC is pricey, though appropriate for its target market — the electric utility industry. Because the 2023 revision has not been effectively “field tested” almost all of the available support literature is, effectively, “sell sheets” for pay-for seminars and written by authors presenting themselves as experts for the battalions of litigators supporting the US utility industry. Without the ability to sell the NESC to prospective “insiders” the NESC would not likely be commercial prospect for IEEE. As the lawsuits and violations and conformance interests make their mark in the fullness of time; we shall see the 2023 NESC “at work”.

Today we begin a list of noteworthy changes to be understood in the next few Power colloquia. See our CALENDAR for the next online meeting.
- New rules 190 through 195 cover photovoltaic generating stations. Rule 116c adds an exception for short lengths of insulated power cables and short-circuit protection if the situation involves fewer than 1,000 volts.
- Rule 320B has been revised to clarify separations that apply to communications and supply in different conduit systems.
- Table 410-4 is based on the latest arc flash testing on live-front transformers.
- Rule 092A adds an exception allowing protection, control, and safety battery systems to not be grounded.
- Rules 234 B1, C1, D1 were revised to better present vertical and horizontal wind clearances, and to coordinate requirements with the new Table 234-7.
- Rule 120A was revised to provide correction factors for clearances on higher elevations.
- Table 253-1 has been revised to reduce the load factor for fiber-reinforced polymer components under wire tension—including dead ends—for Grade C construction.
- Rule 410A now requires a specific radio-frequency safety program for employees who might be exposed.
- In the Clearances section, as well as in the specification of the Grade of Construction in Table 242-1, the Code further clarifies the use of non-hazardous fiber optic cables as telecom providers continue to expand their networks.
- Revisions in the Strength & Loading sections include modified Rule 250C, which addresses extreme wind loading for overhead lines. Two wind maps are now provided instead of the previous single one. A map for Grade B, the highest grade of construction, with a Mean Recurrence Interval (MRI) of 100 years (corresponding to a one percent annual probability of occurrence) is provided in place of the previous 50–90-year MRI map. For Grade C construction, a separate 50-year MRI (two percent annual probability of occurrence) map is now provided. In the previous Code, a factor was applied to the 50–90-year MRI map for application to Grade C.
- Changes were also made to the method of determining the corresponding wind loads, consistent with the latest engineering practices as an example of a Code revision focused on public safety, the ground end of all anchor guys adjacent to regularly traveled pedestrian thoroughfares, such as sidewalks, and similar places where people can be found must include a substantial and conspicuous marker to help prevent accidents. The previous Code did not require the marking of every such anchor guy.
- Significant revisions were made in Section 14 covering batteries. Previous editions of the code were based on lead-acid technology and batteries only used for backup power. The 2023 Code incorporates the new battery technologies and addresses energy storage and backup power.
- A new Section 19 of the code covers photovoltaic generating stations, with sections addressing general codes, location, grounding configurations, vegetation management, DC overcurrent protection, and DC conductors. These new rules accommodate large-scale solar power projects.
- In the Clearances section, all rules for wireless antenna structures have been consolidated in the equipment section (Rule 238 and 239), which makes the Code more user-friendly.
- A new subcommittee was created focusing on generating stations, with the original subcommittee continuing to address substations.
- A working group is investigating Fault Managed Power Systems (FMPS) cables as the technology may be used for 5G networks. The team is looking at possible impacts, including clearances and work rules.
After "slipping a pole" in its revision cadence (owed to the circumstances of the pandemic) the 2023 NESC is rolling out for incorporation by reference into public safety laws relevant to education communities with #WiseCampus ambitions.@ieee_pes @IEEESAhttps://t.co/7EaTBgxa8X pic.twitter.com/jPvZNYzWBi

Several proposals recommending improvements to the 2017 National Electrical Safety Code (NESC) were submitted to the IEEE subcommittees drafting the 2022 revision of the NESC. Some of the proposals deal with coordination with the National Electrical Code — which is now in its 2023 revision cycle. Keep in mind that that NESC is revised every 5 years at the moment; the NEC is revised every 3 years.
The original University of Michigan standards advocacy enterprise has been active in writing the NESC since the 2012 edition and set up a workspace for use by electrical professionals in the education industry. We will be using this workspace as the 2022 NESC continues along its developmental path:
The revision schedule — also revised in response to the circumstances of the pandemic — is linked below::
NESC 2023 Edition Revision Schedule*
The NESC is a standing item on the 4-times monthly teleconferences of the IEEE Education & Healthcare Facilities committee. The next online meeting is shown on the top menu of the IEEE E&H website:
We have a copy of the first draft of the 2023 NESC and welcome anyone to join us for an online examination during any of Power & ICT teleconferences. See our CALENDAR for the next online meeting.
Business unit leaders, facility managers and electrical engineers working in the education facilities industry may be interested in the campus power system reliability database. Forced outages on large research campuses, for example, can have enterprise interruption cost of $100,000 to $1,000,000 per minute. The campus power system forced outage database discriminates between forced outages attributed to public utility interruptions and forced outages attributed to the university-owned power system. The E&H committee will convey some of the discipline applied by the IEEE 1366 technical committee into its study of campus power systems and, ultimately, setting a benchmark for the standard of care for large university power systems.
* The IEEE changed the nominal date of the next edition; likely owed to pandemic-related slowdown typical for most standards developing organizations.
