Facility Management units in educational settlements rarely deal with tree obstruction on overhead supply sources except where off-campus sources provide power to agricultural units. The NESC does not provide specific tree‑species or pruning schedules—that is often left to local utility standards guided by NESC clearances. The IEEE Education & Healthcare Facilities Committee deals with these borderline cases, often collaborating with the IEEE Rural Electric Power Conference.

2022 Guide for Animal Deterrents for Electric Power Supply Substations
Stray Voltage: Sources and Solutions
Abstract. Stray voltage is caused by voltage drop and ground faults and may have its origin on the primary electrical distribution system or on the customer’s secondary electrical system. The rms value of the neutral-to-earth voltage along a primary distribution line may be at a value of zero some distance from the substation depending on the condition of the conductor resistances, grounding resistances, and the amount of load. Neutral-to-earth resistance is not the cause of stray voltage; however, the value of this resistance to earth at a particular location will affect the level of stray voltage. A four-wire single-phase feeder system supplying farm buildings from a single metering point is effective in preventing on-farm secondary neutral voltage drop, provided the four-wire system is extended to all farm loads, and provided no high-magnitude ground faults are present. Isolation of the primary and secondary neutral systems at the distribution transformer is effective in preventing off-farm sources from entering the customer’s system. This separation may be accomplished using a number of commercially available devices.

We revisit first principles regarding the a safety “buffer zone” enforced by code to make high-voltage infrastructure compatible with surrounding development. Ignoring it risks lives, property, and legal issues—hence the detailed regulatory focus on design (calculations), construction (compliance checks), and management (lifetime enforcement), especially critical around expansive campus boundaries. Often these zones define where new facilities can be built.

2025 Group B Proposed Changes to IZC | Complete Monograph for Changes to I-Codes (2630 pages)
National Association of County Engineers
The purpose of the code is to establish minimum requirements to provide a reasonable level of health, safety, property protection and welfare by controlling the design, location, use or occupancy of all buildings and structures through the regulated and orderly development of land and land uses within this jurisdiction.
Municipalities usually have specific land use or zoning considerations to accommodate the unique needs and characteristics of college towns:
This is a relatively new title in the International Code Council catalog; revised every three years in the Group B tranche of titles. Search on character strings such as “zoning” in the link below reveals the ideas that ran through the current revision:

ABSTRACT. As a collective, women’s experience in higher education has been disparate and differential to some men’s experience over the last two centuries, fundamentally based on the societal influences of the time. In the formative years of higher education women attended higher education institutions for social stratification reasons or for marital choice opportunities and to a lesser degree for college outcomes. This study’s purpose was to explore the current motivations of freshmen individuals who identified as female undergraduate students in their first year of pursuing a bachelor’s degree in higher education.
This study used a qualitative research design with semi-structured interviews of five undergraduate women at a mid-sized university campus in the Midwest United States. An initial pre-interview questionnaire was given to participants which provided background and demographic information to ensure an illustrative sample of undergraduate freshmen women who were pursuing a bachelor’s degree.
Considering societal changes for the advancement of women using a historical lens, this study used qualitative research methods to articulate what the current motivations and influences are for women who enroll in higher education in contemporary society. By listening to the women’s stories college going was seen as a viable and important next step in their life journey helping them to achieve their personal and professional goals and aspirations. Both K-12 and post-secondary practitioners and administrators can learn through their voices what matters most to them as they seek to fulfill their personal aspirations for a career to make a difference while having a better life not only for themselves but also for those who they plan to influence through their careers and with their future families.
By understanding women’s motivations for higher education credentials, institutional supports can be developed to foster a deeper understanding of women, as students, in higher education. With this knowledge, K-12 and post-secondary educators and leaders can design pre-college academic programs and student support services to facilitate student discovery built on the aspects that motivate female students to pursue the full higher education experience.

Financial Presentations & Webcasts
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
CMP-11: Lorem
CMP-12: Lorem
CMP-13: Lorem
