NEC Section 226.6 Conductor Size and Support (B) Festoon Lighting
EC&M Article 225: Outside Branch Circuits
Electrical Time: Definition of Festoon Lighting
“Starry Night Over the Rhône” 1888 Vincent van Gogh
Today we refresh our understanding of the moment in illumination technologies for outdoor lighting systems— related but different from our exploration of building interior illumination systems in Illumination 200. Later in 2024 we will roll out Illumination 400 (Holiday illumination) and Illumination 500 which explores litigation related to public illumination technology. As cities-within-cities the shared perimeter of a campus with the host municipality has proven rich in legal controversy and action.
Illumination technology was the original inspiration for the electric utility industry; providing night-time security and transforming every sector of every economy on earth. Lighting load remains the largest component of any building’s electric load — about 35 percent– making it a large target for energy regulations.
Our inquiry begins with selections from the following documents…
International Electrotechnical Commission TC 34 Lighting
IEC 60364 Electrical Installations in Buildings
2023 National Electrical Safety Code
2023 National Electrical Code: Article 410 (While the bulk of the NEC concerns indoor wiring fire hazards, there are passages that inform outdoor lighting wiring safety)
2019 ASHRAE 90.1: Chapter 9 Lighting
Illumination Engineering Society: Various titles
Salt Water River Project: Outdoor Lighting Standards
US DOE-EERE Building Energy Codes Program
…and about 20 other accredited, consortia or ad hoc standards developers and publishers aligned principally with vertical incumbents. Illumination was the original inspiration (i.e. the first “killer app”) for the electrical power industry in every nation. Its best practice literature reflects a fast-moving, shape-changing domain.

Outdoor lighting systems can be owned and maintained by different entities depending on the context and location. Here are some examples of ownership regimes for outdoor lighting systems:
- Public ownership: In this case, outdoor lighting systems are owned and maintained by the local government or municipal authority. The lighting may be installed in public spaces such as parks, streets, and other outdoor areas for the safety and convenience of the public.
- Private ownership: Outdoor lighting systems may be owned by private individuals or organizations. For example, a business owner may install outdoor lighting for security or aesthetic reasons, or a homeowner may install outdoor lighting in their garden or yard.
- Co-owned: Outdoor lighting systems may be owned jointly by multiple entities. For example, a residential community may jointly own and maintain outdoor lighting in their shared spaces such as parking areas, community parks, or recreational facilities.
- Utility ownership: Outdoor lighting systems may be owned and maintained by utility companies such as electric or energy companies. These companies may install and maintain street lights or other lighting systems for the public good.
- Third-party ownership: In some cases, a third-party entity may own and maintain outdoor lighting systems on behalf of a public or private entity. For example, a lighting contractor may install and maintain lighting in a public park on behalf of a local government.
The ownership regime of an outdoor lighting system can have implications for issues such as installation, maintenance, and cost-sharing. It is important to consider ownership when designing and implementing outdoor lighting systems to ensure their long-term effectiveness and sustainability.

Today we break down the stack of regulations, codes, standards and open-source literature governing the safety and sustainability of university-affiliated medical research and healthcare delivery facilities. Because of the complexity of the topic we break down our coverage:
Health 200. Survey of all relevant codes, standards, guidelines and recommended practices for healthcare settings.
Health 400. All of the above with special consideration needed for obstetrics, gynecological and neonatal clinical practice and research.
We limit our interest to systems — water, power, telecommunication and security; for example — that are unique to campus-configured, city-within-city risk aggregations. Electrotechnologies (voltage stability, static electricity control, radio-interference, etc.) in these enterprises are subtle, complex and high risk. Sample titles from legacy best practice literature in this domain are listed below:
American College of Obstetricians and Gynecologists: Levels of Maternal Care
Provision of Care, Treatment, and Services standards for maternal safety
Since our interest lies in the habitable spaces for these enterprises we usually start with a scan of the following titles:
International Building Code Section 407 (Institutional Group I-2) identifies requirements specific to healthcare settings, covering aspects such as fire safety, means of egress, and smoke compartments. Maternity and obstetric facilities within hospitals fall under this classification.

– Common aspects of electrical equipment used in diagnostic imaging equipment
– Equipment for radiotherapy, nuclear medicine and radiation dosimetry
– Electromedical equipment for neonatal care

A relatively new publisher of related standards is the Facility Guidelines Institute. We are monitoring its catalog and its processes. The healthcare facility industry is likely large enough for another non-profit but we have yet to see meaningful leading practice discovery and promulgation that is unrelated to the literature that is already out there.

Healthcare Occupancies
DECEMBER 2025 ICC COMMITTEE ON HEALTHCARE Minutes
2025 REPORT OF THE COMMITTEE ACTION HEARINGS
Safety and sustainability for any facility, not just university-affiliated healthcare facilities, usually begin with an understanding of who, and how, shall occupy the built environment. University settings, with mixed-use occupancy arising spontaneously and temporarily, often present challenges and they are generally well managed.
First principles regarding occupancy classifications for healthcare facilities appear in Section 308 of the International Building Code, Institutional Group I; linked below:
2021 International Building Code Section 308 Institutional Group I
There are thousands of healthcare code compliance functionaries and instructors; most of them supported by trade associations and most of them authoritative. Hewing to our market discipline to track only the concepts that will affect university-affiliated healthcare enterprises only. There are a few noteworthy differences between corporate healthcare businesses and university affiliated healthcare enterprises (usually combined with teaching and research activity) that we identify on this collaboration platform.
We collaborate closely with the IEEE Education & Healthcare Facilities Committee which takes a far more global view of the healthcare industry. That committee meets online 4 times monthly in European and American time zones.
Finally, we encourage our colleagues to participate directly in the ICC Code Development process. Contact Kimberly Paarlberg (kpaarlberg@iccsafe.org) for more information about its healthcare committees and how to participate in the ICC code development process generally. Tranches of ICC titles are developed according to the schedule below:

Healthcare Facilities Code
“The Doctor” 1891 Sir Luke Fildes
The NFPA 99 Healthcare Facilities Code committee develops a distinct consensus document (i.e. “regulatory product”) that is distinct from National Electrical Code Article 517; though there are overlaps and gaps that are the natural consequence of changing technology and regulations. It is worthwhile reviewing the scope of each committee:
NFPA 99 Scope: This Committee shall have primary responsibility for documents that contain criteria for safeguarding patients and health care personnel in the delivery of health care services within health care facilities: a) from fire, explosion, electrical, and related hazards resulting either from the use of anesthetic agents, medical gas equipment, electrical apparatus, and high frequency electricity, or from internal or external incidents that disrupt normal patient care; b) from fire and explosion hazards; c) in connection with the use of hyperbaric and hypobaric facilities for medical purposes; d) through performance, maintenance and testing criteria for electrical systems, both normal and essential; and e) through performance, maintenance and testing, and installation criteria: (1) for vacuum systems for medical or surgical purposes, and (2) for medical gas systems; and f) through performance, maintenance and testing of plumbing, heating, cooling , and ventilating in health care facilities.
NFPA 70 Article 517 Scope: The provisions of this article shall apply to electrical construction and installation criteria in healthcare facilities that provide services to human beings. The requirements in Parts II and III not only apply to single-function buildings but are also intended to be individually applied to their respective forms of occupancy within a multi-function building (e.g. a doctor’s examining room located within a limited care facility would be required to meet the provisions of 517.10) Informational Note: For information concerning performance, maintenance, and testing criteria, refer to the appropriate health care facilities documents.
In short, NFPA 70 Article 517 is intended to focus only on electrical safety issues though electrotechnology complexity and integration in healthcare settings (security, telecommunications, wireless medical devices, fire safety, environmental air control, etc.) usually results in conceptual overlap with other regulatory products such as NFPA 101 (Life Safety Code) and the International Building Code.
Several issues were recently debated by the Article 517 technical committee during the 2023 National Electrical Code Second Draft meetings
- The conditions under which reconditioned electrical equipment be installed in healthcare settings; contingent on listing and re-certification specifics.
- Relaxation of the design rules for feeder and branch circuit sizing through the application of demand factors.
- Application of ground fault circuit interrupters.
- “Rightsizing” feeder and branch circuit power chains (Demand factors in Section 517.22)
- Patient care space categories
- Independence of power sources (517.30)
There are, of course, many others, not the least of which involves emergency management. For over 20 years our concern has been for the interdependency of water and electrical power supply to university hospitals given that many of them are part of district energy systems.
We need to “touch” this code at least once a month because of its interdependence on other consensus products by other standards developing organizations. To do this we refer NFPA 99 standards action to the IEEE Education & Healthcare Facilities Committee which meets online four times monthly in European and American time zones.

Abiit sed non oblitus | Houghton County Michigan
One-hundred-twenty-five years ago, hardy and hard-working Finnish Lutheran immigrants founded a school in Michigan’s Upper Peninsula. Their lives were marked by a gritty quality captured in the Finnish term, sisu – grit and perseverance in the face of adversity. Citing financial difficulties related to demographic changes, the Board of Trustees announced that the Class of 2023 was Finlandia’s final graduating class.
“The Board of Trustees and University President Timothy Pinnow stated the extremely difficult decision is the result of an intensive analysis of Finlandia’s operations after exploring all potentially feasible strategic alternatives, including the rigorous search for new partnerships and reorganization of the institution’s finances. With financial challenges impacting liberal arts colleges throughout the country, Finlandia is no exception….
The combination of demographic changes, with fewer high school graduates available, a steep decrease in interest in going to college among those graduates, a dwindling endowment, and an unbearable debt load have made Finlandia no longer viable…
…Finlandia University has finalized eight Teach-Out Agreements with Adrian College, Bay College, Michigan Technological University, Northeast Wisconsin Technical College, Northern Michigan University, University of Dubuque, Waldorf University, and Wartburg College. Several non-partnering institutions have also made commitments to supporting FinnU students in incredible ways…”

Question: How many households can be supplied with 1 megawatt of power and how large would the solar panel be?
The number of square meters of solar panels required to generate 1 megawatt (MW) of power depends on several factors, including the efficiency of the solar panels, the amount of sunlight available in the location where the solar panels are installed, and the specific technology used.
On average, solar panels have a conversion efficiency of about 15-20%, which means that for every square meter of solar panel area, you can expect to generate between 150 and 200 watts of power in direct sunlight.
So, to generate 1 MW of power, you would need between 5,000 and 6,667 square meters of solar panels (assuming an average efficiency of 17.5%).
There are 2.58999 square meters in one square mile.
To convert 6,667 square meters to square miles, we can divide 6,667 by 2,589.99:
6,667 sq meters / 2,589.99 sq meters/sq mile = 2.572 square miles (rounded to three decimal places).
Answer: Therefore 2.572 square miles of solar panels are required to supply 9345 household of power for 1 hour.
The number of households that can be supplied by 1 megawatt of power depends on a variety of factors, including the amount of electricity each household consumes, the time of day, and the season.
However, as a rough estimate, the US Energy Information Administration (EIA) reports that in 2020, the average US household consumed about 9,369 kilowatt-hours (kWh) of electricity per year, which is equivalent to an average of 0.107 MW of power.
Based on this average, 1 MW of power could supply approximately 9,345 households (1,000,000 watts / 0.107 MW per household) with electricity for one hour, assuming that all households are consuming the average amount of electricity.
Again, this is a rough estimate, and the actual number of households that can be supplied by 1 MW will depend on various factors such as the region, the time of day, and the actual energy consumption of each household.
Discussion: A typical residential lot is one-half acre. Rounding 9345 households to 10,000 households; the households themselves have a footprint of 7.8125 square miles; with 1/3rd of the 2.572 square miles for 1 megawatt taken up by the panels.
