This British festive pastry has origins dating back to the 13th century when European Crusaders returned from the Middle East with recipes containing meats, fruits, and spices. These early pies, known as “mincemeat pies,” combined minced meat (usually mutton), suet, fruits, and spices such as cinnamon, cloves, and nutmeg, symbolizing the gifts of the Magi. In the 16th century, the pies were rectangular, representing Jesus’ crib.
Over time, the meat content reduced, and by the Victorian era, the recipe had evolved to primarily include dried fruits, suet, and spices, aligning with the modern version of the mince pie. Traditionally enjoyed during the Christmas season, mince pies are now small, round pastries filled with a mixture called mincemeat, which typically contains no meat but a blend of dried fruits, sugar, spices, and sometimes brandy or other spirits.
Last night, after a 3 year break, we were delighted to once again host our Festive Networking Drinks 🎄 in person, at the Oxford & Cambridge Club, London.
We had a great turn out with almost 60 fellows, students & alumni braving the cold to socialise & network with their peers. pic.twitter.com/WX7aVskMsi

The University of Michigan has supported the voice of the United States education facility industry since 1993 — the second longest tenure of any voice in the United States. That voice has survived several organizational changes but remains intact and will continue its Safer-Simpler-Lower Cost-Longer Lasting priorities on Code Panel 3 in the 2029 Edition.
Today, during our customary “Open Door” teleconference we will examine the technical concepts under the purview of Code Panel 3; among them:
Article 206 Signaling Circuits
Article 300 General Requirements for Wiring Methods and Materials
Article 335 Instrumentation Tray Cable
Article 590 Temporary Installations
Chapter 7 Large sections of limited energy cabling for signaling and information technology
Since the lifespan of educational buildings make the building core and shell susceptible to multiple changes not typically associated with commercial buildings, additional pathways should be placed in areas where the core and shell components of the facility are likely to re-main for extended periods of time
It is recommended that all areas of an educational building have wireless coverage unless prohibited
ASHRAE 90.4 defines an alternate compliance path, specific to data centers, while the compliance requirements for “non-data center” components are contained in ASHRAE 90.1 . The 90.4 structure also streamlines the ongoing maintenance process as well ensures that Standards 90.1 and 90.4 stay in their respective lanes to avoid any overlap and redundancies relating to the technical and administrative boundaries. Updates to ASHRAE 90.1 will still include the alternate compliance path defined in ASHRAE 90.4. Conversely the 2022 Edition of 90.4-2022 refers to ASHRAE 90.1-2022; cross-referencing one another synchronously

This title resides on the standing agenda of our Infotech 400 colloquium; hosted several times per year and as close coupled with the annual meetings of ASHRAE International as possible. Technical committees generally meet during these meetings make decisions about the ASHRAE catalog. The next all committee conference will be hostedJanuary 20-24, 2024 in Chicago. As always we encourage education industry facility managers, energy conservation workgroups and sustainability professionals to participate directly in the ASHRAE consensus standard development process. It is one of the better facilities out there.
Proposed Addendum g makes changes to definitions were modified in section 3 and mandatory language in Section 6 to support the regulation of process heat and process ventilation was moved in the section for clarity. Other changes are added based on comments from the first public review including changes to informative notes.
Consultation closes June 4th
Update: February 10, 2023
The most actively managed consensus standard for data center energy supply operating in education communities (and most others) is not published by the IEEE but rather by ASHRAE International — ASHRAE 90.4 Energy Standard for Data Centers (2019). It is not required to be a free access title although anyone may participate in its development. It is copyrighted and ready for purchase but, for our purpose here, we need only examine its scope and purpose. A superceded version of 90.4 is available in the link below:
It is likely that the technical committee charged with updating this standard are already at work preparing an updated version that will supercede the 2019 Edition. CLICK HERE for a listing of Project Committee Interim Meetings.
We maintain many titles from the ASHRAE catalog on the standing agenda of our Mechanical, Energy 200/400, Data and Cloud teleconferences. See our CALENDAR for the next online meeting; open to everyone.
Originally posted Summer 2020.
ASHRAE International has released four new addenda to its energy conservation consensus document ASHRAE 90.4-2016 Energy Standard for Data Centers. This document establishes the minimum energy efficiency requirements of data centers for design and construction, for the creation of a plan for operation and maintenance and for utilization of on-site or off-site renewable energy resources.
It is a relatively new document more fully explained in an article published by ASHRAE in 2016 (Click here). The addenda described briefly:
Addendum a – clarifies existing requirements in Section 6.5 as well as introduce new provisions to encourage heat recovery within data centers.
Addendum b – clarifies existing requirements in Sections 6 and 11 and to provide guidance for taking credit for renewable energy systems.
Addendum d – a response to a Request for Interpretation on the 90.4 consideration of DieselRotary UPS Systems (DRUPS) and the corresponding accounting of these systems in the Electrical Loss Component (ELC). In crafting the IC, the committee also identified several marginal changes to 90.4 definitions and passages in Section 8 that would add further clarity to the issue. This addendum contains the proposed changes for that aim as well as other minor changes to correct spelling or text errors, incorporate the latest ELC values into Section 11, and to refresh information in the Normative Reference.
Addendum e adds language to Section 11 intended to clarify how compliance with Standard 90.4 can be achieved through the use of shared systems.
Comments are due September 6th. Until this deadline you may review the changes and comment upon them by by CLICKING HERE

Municipalities usually have specific land use or zoning considerations to accommodate the unique needs and characteristics of college towns:
Mixed-Use Zoning: Cities with colleges and universities often employ mixed-use zoning strategies to encourage a vibrant and diverse urban environment. This zoning approach allows for a combination of residential, commercial, and institutional uses within the same area, fostering a sense of community and facilitating interactions between students, faculty, and residents.
Height and Density Restrictions: Due to the presence of educational institutions, cities may have specific regulations on building height and density to ensure compatibility with the surrounding neighborhoods and maintain the character of the area. These restrictions help balance the need for development with the preservation of the existing urban fabric.
Student Housing: Cities with colleges and universities may have regulations or guidelines for student housing to ensure an adequate supply of affordable and safe accommodations for students. This can include requirements for minimum bedroom sizes, occupancy limits, and proximity to campus.
Parking and Transportation: Given the concentration of students, faculty, and staff, parking and transportation considerations are crucial. Cities may require educational institutions to provide parking facilities or implement transportation demand management strategies, such as promoting public transit use, cycling infrastructure, and pedestrian-friendly designs.
Community Engagement: Some cities encourage colleges and universities to engage with the local community through formalized agreements or community benefit plans. These may include commitments to support local businesses, contribute to neighborhood improvement projects, or provide educational and cultural resources to residents.
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:
Reed v. Town of Gilbert (2015): This Supreme Court case involved a challenge to the town of Gilbert, Arizona’s sign code, which regulated the size, location, and duration of signs based on their content. The court held that the sign code was a content-based restriction on speech and therefore subject to strict scrutiny.
City of Ladue v. Gilleo (1994): In this Supreme Court case, the court struck down a municipal ordinance that banned the display of signs on residential property, except for signs that fell within specific exemptions. The court held that the ban was an unconstitutional restriction on the freedom of speech.
Metromedia, Inc. v. San Diego (1981): This Supreme Court case involved a challenge to a San Diego ordinance that banned off-premises advertising signs while allowing on-premises signs. The court held that the ordinance was an unconstitutional restriction on free speech, as it discriminated against certain types of speech.
City of Ladue v. Center for the Study of Responsive Law, Inc. (1980): In this Supreme Court case, the court upheld a municipal ordinance that prohibited the display of signs on public property, but only if the signs were posted for longer than 10 days. The court held that the ordinance was a valid time, place, and manner restriction on speech.
City of Boerne v. Flores (1997): This Supreme Court case involved a challenge to a municipal sign code that regulated the size, location, and content of signs in the city. The court held that the sign code violated the Religious Freedom Restoration Act, as it burdened the exercise of religion without a compelling government interest.
100 years ago, the Supreme Court made it clear in Pierce v. Society of Sisters: raising children is the responsibility of parents, not the government.

“…O chestnut tree;, great rooted blossomer, Are you the leaf, the blossom or the bold? O body swayed to music, O brightening glance, How can we know the dancer from the dance?”
We sweep through the world’s three major time zones; updating our understanding of the literature at the technical foundation of education community safety and sustainability in those time zones 24 times per day. We generally eschew “over-coding” web pages to sustain speed, revision cadence and richness of content as peak priority. We do not provide a search facility because of copyrights of publishers and time sensitivity of almost everything we do.
Our daily colloquia are typically doing sessions; with non-USA titles receiving priority until 16:00 UTC and all other titles thereafter. We assume policy objectives are established (Safer-Simpler-Lower-Cost, Longer-Lasting). Because we necessarily get into the weeds, and because much of the content is time-sensitive and copyright protected, we usually schedule a separate time slot to hammer on technical specifics so that our response to consultations are meaningful and contribute to the goals of the standards developing organization and to the goals of stewards of education community real assets — typically the largest real asset owned by any US state and about 50 percent of its annual budget.
1. Leviathan. We track noteworthy legislative proposals in the United States 118th Congress. Not many deal specifically with education community real assets since the relevant legislation is already under administrative control of various Executive Branch Departments such as the Department of Education.
We do not advocate in legislative activity at any level. We respond to public consultations but there it ends.
We track federal legislative action because it provides a stroboscopic view of the moment — the “national conversation”– in communities that are simultaneously a business and a culture. Even though more than 90 percent of such proposals are at the mercy of the party leadership the process does enlighten the strengths and weakness of a governance system run entirely through the counties on the periphery of Washington D.C. It is impossible to solve technical problems in facilities without sensitivity to the zietgeist that has accelerated in education communities everywhere.

The recent tragedy inspires a need to review relevant safety standards. Today, a very brief examination and discussion about whether there is an enforceable standard solution that already exists, or is there an affordable solution to remediate a gap. Just a very cursory review today during our Open Office Hour.
We examine the proposals for the 2028 National Electrical Safety Code; including our own. The 2026 National Electrical Code where sit on CMP-15 overseeing health care facility electrical issues should be released any day now. We have one proposal on the agenda of the International Code Council’s Group B Committee Action Hearings in Cleveland in October. Balloting on the next IEEE Gold Book on reliability should begin.

Recap of the May meetings of the Industrial & Commercial Power Systems Conference in Las Vegas. The conference ended the day before the beginning of the 3-day Memorial Day weekend in the United States so we’re pressed for time; given all that happened.
We can use our last meeting’s agenda to refresh the status of the issues.
We typically break down our discussion into the topics listed below:
Codes & Standards:
While IAS/I&CPS has directed votes on the NEC; Mike is the only I&CPS member who is actually submitting proposals and responses to codes and standards developers to the more dominant SDO’s — International Code Council, ASHRAE International, UL, ASTM International, IEC & ISO. Mike maintains his offer to train the next generation of “code writers and vote getters”
Performance-based building premises feeder design has been proposed for the better part of ten NEC revision cycles. The objective of these proposals is to reduce material, labor and energy waste owed to the branch and feeder sizing rules that are prescriptive in Articles 210-235. Our work in service and lighting branch circuit design has been largely successful. A great deal of building interior power chain involves feeders — the network upstream from branch circuit panels but down stream from building service panel.
Our history of advocating for developing this approach, inspired by the NFPA 101 Guide to Alternative Approaches to Life Safety, and recounted in recent proposals for installing performance-based electrical feeder design into the International Building Code, appears in the link below:
Access to this draft paper for presentation at any conference that will receive it — NFPA, ICC or IEEE (or even ASHRAE) will be available for review at the link below:
NFPA 110 Definitions of Public Utility v. Merchant Utility
NFPA 72 “Definition of Dormitory Suite” and related proposals
Buildings:
Renovation economics, Smart contracts in electrical construction. UMich leadership in aluminum wiring statements in the NEC should be used to reduce wiring costs.
This paper details primary considerations in estimating the life cycle of a campus medium voltage distribution grid. Some colleges and universities are selling their entire power grid to private companies. Mike has been following these transactions but cannot do it alone.
Variable Architecture Multi-Island Microgrids
District energy:
Generator stator winding failures and implications upon insurance premiums. David Shipp and Sergio Panetta. Mike suggests more coverage of retro-fit and lapsed life cycle technicals for insurance companies setting premiums.
Reliability:
Bob Arno’s leadership in updating the Gold Book.
Mike will expand the sample set in Table 10-35, page 293 from the <75 data points in the 1975 survey to >1000 data points. Bob will set up meeting with Peyton at US Army Corps of Engineers.
Reliability of merchant utility distribution systems remains pretty much a local matter. The 2023 Edition of the NESC shows modest improvement in the vocabulary of reliability concepts. For the 2028 Edition Mike submitted several proposals to at least reference IEEE titles in the distribution reliability domain. It seems odd (at least to Mike) that the NESC committees do not even reference IEEE technical literature such as Bob’s Gold Book which has been active for decades. Mike will continue to propose changes in other standards catalogs — such as ASTM, ASHRAE and ICC — which may be more responsive to best practice assertions. Ultimately, improvements will require state public utility commission regulations — and we support increases in tariffs so that utilities can afford these improvements.
Mike needs help from IEEE Piscataway on standard WordPress theme limitations for the data collection platform.
Mike will update the campus power outage database.
Healthcare:
Giuseppe Parise’s recent work in Italian power grid to its hospitals, given its elevated earthquake risk. Mike’s review of Giuseppe’s paper:
Mike and David Shipp will prepare a position paper for the Harvard Healthcare Management Journal on reliability advantages of impedance grounding for the larger systems.
The Internet of Bodies
Forensics:
Giuseppe’s session was noteworthy for illuminating the similarity and differences between the Italian and US legal system in handling electrotechnology issues.
Mike will restock the committee’s library of lawsuits transactions.
Ports:
Giuseppe updates on the energy and security issues of international ports. Mike limits his time in this committee even though the State of Michigan has the most fresh water international ports in the world.
A PROPOSED GUIDE FOR THE ENERGY PLAN AND ELECTRICAL INFRASTRUCTURE OF A PORT
Other:
Proposals to the 2028 National Electrical Safety Code: Accepted Best Practice, exterior switchgear guarding, scope expansion into ICC and ASHRAE catalog,
Apparently both the Dot Standards and the Color Books will continue parallel development. Only the Gold Book is being updated; led by Bob Arno. Mike admitted confusion but reminded everyone that any references to IEEE best practice literature in the NFPA catalog, was installed Mike himself (who would like some backup help)
Mike assured Christel Hunter (General Cable) that his proposals for reducing the 180 VA per-outlet requirements, and the performance-base design allowance for building interior feeders do not violate the results of the Neher-McGrath calculation used for conductor sizing. All insulation and conducting material thermal limits are unaffected.
Other informal discussions centered on the rising cost of copper wiring and the implications for the global electrotechnical transformation involving the build out of quantum computing and autonomous vehicles. Few expressed optimism that government ambitions for the same could be met in any practical way.
Are students avoiding use of Chat GPT for energy conservation reasons? Mike will be breaking out this topic for a dedicated standards inquiry session:
The current full complement of five FERC commissioners is relatively new as of December 23, 2025. The two most recent additions — Chairman Laura V. Swett (term expiring June 30, 2030) and Commissioner David A. LaCerte (term expiring June 30, 2026) — were confirmed by the U.S. Senate on October 7, 2025.
§
This restored FERC to its full five members after prior vacancies and transitions earlier in the year.The other commissioners (David Rosner, Lindsay S. See, and Judy W. Chang) have been in place since mid-2024 or earlier, but the current lineup only fully formed about two and a half months ago.
§
This followed changes tied to the new administration, including shifts in majority and leadership.
This title sets the standard of care for construction, operation and maintenance of power and telecommunication infrastructure on the supply side of the point of common coupling. It is the first title to contemplate when weather disasters happen; with most public utilities bound to its best practice assertions by statute. Pre-print of Change Proposals for changes to appear in 2028 Edition will be available by 1 July 2025; with 24 March 2026 as the close date for comments on proposed changes.
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”.
Change Proposals are now being accepted from the public for revisions to the 2023 Edition of the National Electrical Safety Code® #NESC through 15 May 2024.
The new code goes into effect 1 February 2023, but is now available for access on IEEE Xplore! Produced exclusively by IEEE, the National Electrical Safety Code (NESC) specifies best practices for the safety of electric supply and communication utility systems at both public and private utilities. The bibliography is expanding rapidly:
The IEEE NESC technical committee has released a “fast track” review of proposed changes to fault-managed power system best practice:
CP5605 Provides a definition of new Fault Managed Power System (FMPS) circuits used for the powering of
communications equipment clearly defines what constitutes a FMPS circuit for the purposes of application of the NESC
Rules of 224 and 344 https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXtAAAAADhMnPs
CP5606 Provides new definitions of Communication Lines to help ensure that Fault Managed Power Systems (FMPS)
circuits used for the exclusive powering of communications equipment are clearly identified as communications lines
and makes an explicit connection to Rule 224B where the applicable rules for such powering circuits are found. https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXpAAAAAFfvWIs
CP5607 The addition of this exception permits cables containing Fault Managed Power System (FMPS) circuits used for
the exclusive powering of communications equipment to be installed without a shield. https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXuAAAAAEEt3p4
CP5608 The addition of this exception permits cables containing Fault Managed Power System (FMPS) circuits used for
the exclusive powering of communications equipment to be installed without a shield. https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXvAAAAAGrzyeI
We refer them to the IEEE Education & Healthcare Facilities Committee for further action, if any.
August 5, 2022
We collaborate closely with the IEEE Education & Healthcare Facilities Committee (IEEE E&H) to negotiate the standard of care for power security on the #SmartCampus since many campus power systems are larger than publicly regulated utilities. Even when they are smaller, the guidance in building the premise wiring system — whether the premise is within a building, outside the building (in which the entire geography of the campus footprint is the premise), is inspired by IEEE Standards Association administrated technical committees.

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.
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 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.

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-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
