Our tenure in the 2026 National Electrical Code will result in at least a 10 percent reduction in the cost of building premise wiring — (mostly in the feeder power chain) — in healthcare facilities; based on the results of last month’s meeting of Code Making Panel 15.
Assuming electrical power infrastructure is 15 percent of in a $920 million facility like this (excluding interior moveable fixtures), that would have meant an approximate $14 million reduction in cost. That cost savings cannot be realized because it was designed to an earlier version of the National Electrical Code.

Abstract. A method is developed for representing any communication system geometrically. Messages and the corresponding signals are points in two “function spaces,” and the modulation process is a mapping of one space into the other. Using this representation, a number of results in communication theory are deduced concerning expansion and compression of bandwidth and the threshold effect. Formulas are found for the maximum rate of transmission of binary digits over a system when the signal is perturbed by various types of noise. Some of the properties of “ideal” systems which transmit at this maxmum rate are discussed. The equivalent number of binary digits per second for certain information sources is calculated.
Claude Shannon (30 April 1916 in Petoskey, Michigan, USA – 24 Feb 2001 in Medford, Massachusetts, USA) founded the subject of information theory and he proposed a linear schematic model of a communications system.

Abstract: A specific land is required to design the transmission line to construct effectively and maintain properly is called right of way of transmission line. It is calculated by considering mainly three electrical quantity related transmission line such as electric field, magnetic field and radio interference. Corona effect is considered for the evolution of right of way. By considering these parameters, it provide idea related to effect surrounding the area nearby transmission line.
The determination of transmission line right of way for public electric utilities typically involves a combination of legal considerations, regulatory requirements, environmental assessments, and public engagement:
Planning and Route Selection: Public electric utilities assess their power transmission needs based on factors such as population growth, energy demand, and infrastructure upgrades. They consider various potential routes and alternatives, taking into account factors like terrain, existing infrastructure, land use, and environmental sensitivities.
Environmental and Impact Assessments: Utilities conduct environmental and impact assessments to evaluate the potential effects of the proposed transmission line routes. These assessments examine factors such as wildlife habitats, endangered species, wetlands, water bodies, cultural or historical sites, and scenic landscapes. The purpose is to identify potential impacts and propose mitigation measures.
Regulatory and Permitting Process: Public utilities must comply with applicable laws and regulations governing transmission line development. This includes obtaining necessary permits and approvals from relevant regulatory agencies at the federal, state, and local levels. The requirements vary depending on the jurisdiction, but they often involve environmental agencies, land management agencies, and public utility commissions.
Public Engagement and Consultation: Utilities engage in public consultation and outreach to gather feedback from affected communities, landowners, and stakeholders. They conduct public hearings, open houses, and meetings to inform the public about the project, address concerns, and consider alternative routes suggested by the community. This engagement helps ensure transparency and public input in the decision-making process.
Negotiations and Eminent Domain: Utilities negotiate with landowners along the proposed transmission line route to acquire the necessary right of way. In some cases, if an agreement cannot be reached, utilities may exercise eminent domain, which is a legal process that allows them to acquire the land for public use while providing just compensation to the affected landowner.
Legal Framework: The legal framework for determining transmission line right of way varies by jurisdiction. Laws related to land use, zoning, environmental protection, and eminent domain play a role in defining the process and requirements for securing right of way.
Procedures vary depending on the country, state, or region where the transmission line is being developed. Local regulations, environmental conditions, and public engagement practices will influence the overall process.
Abstract: Documented in this guide are methods and designs to mitigate interruptions, equipment damage, and personnel safety issues resulting from animal intrusions into electric power supply substations, thereby improving reliability and safety, and minimizing the associated revenue loss.
Scope: This guide documents methods and designs to mitigate interruptions, equipment damage, and personnel safety issues resulting from animal intrusions into electric power supply substations, thereby improving reliability and safety, and minimizing the associated revenue loss.
Purpose: Intrusion by animals into electric power supply substations has been a problem experienced by most of the electric utility industry. The costs associated with outages caused by animals continue to escalate. Although animal problems differ in nature geographically, the damage to equipment, interruption of or loss of service to customers, and safety problems encountered by operating personnel result in similar general concerns. This guide identifies various animals, the problems they cause, and mitigation methods. Further, it recommends criteria for applying mitigation methods, documents survey-reported effectiveness of various methods, and recommends factors for evaluating effectiveness of methods once they are applied.
Ampere current flows through copper or aluminum conductor due to the movement of free electrons in response to an applied electric field of varying voltages. Each copper or aluminum contributes one free electron to the electron sea, creating a vast reservoir of mobile charge carriers. When a potential difference (voltage) is applied across the ends of the conductor, an electric field is established within the conductor. This field exerts a force on the free electrons, causing them to move in the direction of the electric field. The resulting current flow can be transformed into different forms depending on the nature of the device.
Heating: When current flows through a resistor, it encounters resistance, which causes the resistor to heat up. This is the principle behind electric heaters, toasters, and incandescent light bulbs.
Mechanical Work: Current flowing through an electric motor creates a magnetic field, which interacts with the magnetic field of the motor’s permanent magnets or electromagnets. This interaction generates a mechanical force, causing the motor to rotate. Thus, electrical energy is converted into mechanical energy; including sound.
Light: In an incandescent light bulb, a filament heats up ( a quantum phenomena) due to the current passing through it. This is an example of electrical energy being converted into light energy; including the chemical energy through light emitting diodes
Today we dwell on how conductors are specified and installed in building premise wiring systems primarily; with some attention to paths designed to carry current flowing through unwanted paths (ground faults, phase imbalance, etc). In the time we have we will review the present state of the best practice literature developed by the organizations listed below:
Other organizations such as the National Electrical Manufacturers Association, ASTM International, Underwriter Laboratories, also set product and installation standards. Data center wiring; fiber-optic and low-voltage control wiring is covered in other colloquia (e.g. Infotech and Security) and coordinated with the IEEE Education & Healthcare Facilities Committee.

Some of the common electro-technologies used in a neonatal care unit include:
Incubators: These temperature-controlled units create a controlled environment to keep premature or sick infants warm and protected.
Ventilators: Mechanical ventilators assist newborns with respiratory distress by delivering oxygen and helping them breathe.
Monitors: These devices track vital signs such as heart rate, oxygen levels, blood pressure, and temperature to ensure the baby’s health and detect any abnormalities.
Phototherapy Lights: Special lights are used to treat jaundice in newborns, helping to break down excess bilirubin in the blood.
Intravenous Pumps: These pumps are used to deliver medications, fluids, and nutrients directly into the baby’s bloodstream.
Feeding Tubes: For infants who are unable to feed orally, feeding tubes are used to deliver breast milk or formula directly into their stomach.
Blood Gas Analyzers: These machines measure the levels of oxygen, carbon dioxide, and other gases in a baby’s blood to monitor respiratory status and acid-base balance.
Infusion Pumps: Used to administer controlled amounts of fluids, medications, or nutrients to newborns.
CPAP/BiPAP Machines: Continuous Positive Airway Pressure (CPAP) and Bi-level Positive Airway Pressure (BiPAP) machines help newborns with breathing difficulties by providing a continuous flow of air pressure.
Neonatal Resuscitation Equipment: This includes equipment such as resuscitation bags, endotracheal tubes, laryngoscopes, and suction devices used during emergency situations to assist with newborn resuscitation.
It’s important to note that specific tools and equipment may vary depending on the level of neonatal care provided by the unit, the needs of the infants, and the policies of the healthcare facility.
Neonatal care, as a specialized field, has been shaped by the contributions of several pioneers in medicine. Here are a few notable figures who have made significant advancements in neonatal care:
Dr. Virginia Apgar was an American obstetrical anesthesiologist who developed the Apgar score in 1952. The Apgar score is a quick assessment tool used to evaluate the overall health of newborns immediately after birth. It assesses the baby’s heart rate, respiratory effort, muscle tone, reflex irritability, and color, providing valuable information for prompt intervention and monitoring.
Dr. Martin Couney, a pioneering physician, established incubator exhibits at world fairs and amusement parks in the early 20th century. He promoted the use of incubators to care for premature infants and played a significant role in popularizing the concept of neonatal intensive care.
Dr. Virginia A. Apgar, an American pediatrician and neonatologist, made significant contributions to the field of neonatology. She specialized in the care of premature infants and conducted extensive research on neonatal resuscitation and newborn health. She also developed the Apgar scoring system, although unrelated to Dr. Virginia Apgar mentioned earlier.
Dr. Lula O. Lubchenco was an influential researcher and neonatologist who made important contributions to the understanding of newborn growth and development. She developed the Lubchenco Growth Chart, which provides a standardized assessment of a newborn’s size and gestational age, aiding in the identification and monitoring of growth abnormalities.
Dr. Mary Ellen Avery was a renowned American pediatrician and researcher whose work focused on understanding and treating respiratory distress syndrome (RDS) in premature infants. She identified the importance of surfactant deficiency in RDS and contributed to the development of surfactant replacement therapy, revolutionizing the care of preterm infants.
These individuals, among many others, have played pivotal roles in advancing the field of neonatal care, improving the understanding, diagnosis, treatment, and overall outcomes for newborn infants.
Many land grant colleges and universities are stewards of agricultural facilities that require reliable electrical power that is safe and sustainable for livestock well off the core campus distribution grid. Today we examine the 2026 National Electrical Code safe electric service rules with an eye toward the close date of April 6th for public input on the 2029 NEC.

Public response to the First Draft of the 2026 National Electrical Code will be received until August 28, 2024. We coordinate our approach to the entire NFPA electrical suite with the IEEE Education & Healthcare Facilities Committee which meets 4 times monthly. We typically refer to previous transcripts of technical committee actions to inform any changes (improvements) that we propose, if any.
We maintain this issue on the standing agenda of our Power and Nourriture (Food) colloquia. Feel free to join us with the login credentials at the upper right of our home page.
IEC 60364-1:2025 (6th edition, published September 5, 2025) replaces the 2005 edition (5th edition). This is a major technical revision with significant changes which we will cover throughout 2026 — after NESC and NEC work

Technical Committee 64 develops the International Electrotechnical Commission consensus product that covers similar territory for the global electrical power industry as NFPA 70 (National Electrical Code). Keep in mind that the safety traditions of the NFPA suite of consensus products are inspired by fire safety considerations. IEC 60363 Electrical installations and protection against electric shock — the parent document that applies to the wiring systems of education and healthcare facilities — was inspired from voltage safety.
– concerning protection against electric shock arising from equipment, from installations and from systems without limit of voltage,
– for the design, erection foreseeable correct use and verification of all kind of electrical installations at supply voltage up to 1 kV a.c or 1,5 kV d.c., except those installations covered by the following IEC committees: TC 9, TC 18, TC 44, TC 97, TC99
– in co-ordination with TC 99, concerning requirements additional to those of TC 99 for the design, erection and verification of electrical installations of buildings above 1kV up to 35kV.
The object of the standards shall be:
– to lay down requirements for installation and co-ordination of electrical equipment
– to lay down basic safety requirements for protection against electric shock for use by technical committees
– to lay down safety requirements for protection against other hazards arising from the use of electricity
– to give general guidance to IEC member countries that may have need of such requirements
– and to facilitate international exchanges that may be hampered by differences in national regulations.
The standards will not cover individual items of electrical equipment other than their selection for use. Safety Pilot Function: Protection against electric shock.
Since neither the USNA National Committee to the IEC (USNA/IEC), nor the US Technical Advisory Administrator (National Electrical Manufacturers Association) has a workspace set up for responding to IEC 60364 calls for public comment, we set one up for ourselves several years ago for education facility and electrical engineering faculty and students:
Note that anyone in the world is welcomed to comment upon IEC documents, contingent upon obtaining (free) login credentials. To review the the strike-and-bold you will need login credentials. Alternatively, you may click in to the 4-times monthly teleconferences of the IEEE Education & Healthcare Facilities Committee. See our CALENDAR for the next online meeting.
