In-person RES Tutoring at Dr.

Walter Cooper Academy

A schedule of weekly in-person tutoring continued on Tuesday, May 2nd, RES/Bergmann Tutor, Katelyn Burns, spent about two hours working with several of our “Cooper Scholars” from Mrs. Sanzotta’s First Grade.

Upon arrival, Katelyn received a basket of lesson-support materials from the teacher. She was then guided, by her students, to the School Library, and they selected a quiet corner in which to spend about 20 minutes working on letter, number word and word-picture association problems and games.

Over the course of the next 90 - 120 minutes, Katelyn worked with four additional students, on similar reading, word association and math lessons. A 2021 engineering graduate of the University of Buffalo, Katelyn is a member of the four-person RES/Bergmann Tutoring Team.

The second half of the 2022-23 School Year, at Dr. Walter Cooper Academy, now includes in-person tutoring by the RES Tutoring Team...

The need is great… We have a large number of students in need of the one-on-one support that comes from in-person attention to their individual learning needs.

Won’t you please consider joining our 2022-23 RES Tutoring Team… Else please consider joining our RES Tutors for the 2023-24 School Year?

Technical Corner - Electrical Engineering Focus

This month’s article focuses on ampacity adjustment of conductors within a dwelling.

Basically, copper and aluminum wires do not like heat. When there is current flow within a wire then they begin to generate heat. Other sources of heat within a wire are from the ambient temperature of the air or the heat generated by other conductors within the same conduit to name a few. So, during design this will need to be recognized and compensated for.

Diversity of the load a cable segment feeds is also another factor that comes into play with dwellings. Diversity is looking at how much electrical load is drawing current at the same time. Turns out with dwelling units the diversity is quite significant. So, NEC 2023 section 310.12 recognizes this and allows a derating factor to be used on the service-entrance conductors, which feed the entire load of the dwelling

The concept here is that the more devices connected to the service the more chance that all of them will not be operating at the same time, so you are able to apply an 83% adjustment factor for the cabling segments shown in this illustration.

Please note the segment feeding another panelboard from Apartment 2 does not apply to this adjustment factor rule and must be sized using the typical 310.16 ampacity tables.

Example: What size aluminum wire will you need to run from Apartment 2 to a 100-amp sub-panel shown in the illustration?

(Typical sub-panel installation)

Cable Type: SE Cable with 90-degree XHHW-2 conductors within (see photo)

What is interesting here is that this sub-panel does not feed the entire load of the dwelling so you would refer to table 310.16 and find that #1 AWG would be sufficient using the 75 degree column. (Refer to NEC Article 338 (illustrated version)-wire larger than #10 so use 75 degree column not the 60 degree column)

If this was the segment of wire ahead of the panel, or service, you could use table 310.12(A) which indicates one size smaller which is #2 AWG. This is allowed due to the 83% rule mentioned above. The amperage of the panel is 100A and if we take 83% of this, we would need a wire segment sized for 83 amps minimum.

When you round up you would get a #2AWG aluminum rated for 90amps.

Hopefully this article finds you well and can be used as a reference for your project needs. If anyone would like to contribute to the RES magazine and add an article or would like to request information on a specific topic (not limited to Electrical) just email me, beliasz@bergmannpc.com. As always, any comments are appreciated…! Thank you for reading.

Professional Highlight

Bill founded Optimation to provide engineering services for industrial and manufacturing applications during a time when most engineering firms were focused on roads, bridges, building and infrastructure. Optimation expanded to industrial design and fabrication services when they purchased the construction division from Kodak in 2006. More recently Bill helped to transition the ownership of Optimation to Re:Build Manufacturing. Re:Build has the business plan to restore manufacturing to the United States. Optimation is happy to be part of a much larger and growing organization with a shared vision. In addition to historic clients in chemical, food, pharmaceutical, glass, oil and gas and more established industries, Optimation is now focused heavily in industries related to the green energy revolution. Major projects include hydrogen, carbon capture, lithium batteries, wind and solar. Optimation has built millions of dollars in systems to generate green hydrogen, test fuel cell, convert methane to methanol, and assemble lithium batteries. The theme of the Olympics in Japan for 2020 (which didn't happen) was Sustainability and they wanted to have a jet fly-over with jets fueled by farm waste. OTI was commissioned to create a distillation system to convert farm waste into jet fuel. In partnership with GE, OTI built the world’s largest 3D printer. The unit was designed to print a concrete tower 65 feet tall to position the windmill higher and increase the power generated. There is a rush to invest and build green infrastructure and Re:Build Optimation is a part of it.

Interests & Hobbies

Running - Bill has always enjoyed running. He started running in marathons when he was 64. He’s run 16 marathons including running the Boston Marathon 8 times.

Bill and his wife live in an underground house he designed and built himself (with the help of all of his friends). It includes all the energy savings technology available when he built it 40 years ago.

Bill is converting a 1951 Dodge Pickup to an EV. He’s watched hundreds of youtube videos and searched dozens of websites for the parts and pieces he needs on the project.

Selecting and implementing business applications is an important part of the successful operation of any modern organization. When planned and selected well, new applications can streamline processes, improve productivity, increase profitability, and enable organizations to adapt to changing opportunities. Selecting and implementing business applications can be a complex and challenging process.

Here are some things to keep in mind when selecting and implementing business applications:

When considering new business applications, a critical step is understanding and agreeing to the requirements and objectives, this documents the value the application provides to the organization and defines the expected results of using it.

It is valuable to ensure there is representation of different roles that will use or support the application, including employees, managers, and IT leadership. Involving these stakeholders early in the decision-making process can help ensure that all requirements and opinions are considered, prioritized, and that the application is a good fit for the organization. You likely have multiple individuals on the team with valuable insight.

• Speaking of value to the organization, what are the available funds to cover licensing, implementation, training, data migration, data integration and ongoing support?

• Does self-hosting make the most sense or is a mobile or software as a service (SaaS) solution a better fit based on the use case?

At a minimum IT’s responsibility is to ensure applications being considered will be functional and supportable in your organization. Looking to compatibility with end user devices, compliance, policies, infrastructure and that they can support the solution. Depending what data the application processes, IT will look to ensure it is appropriately secured, and that the quality of the data is being managed to ensure integrity and reliability. IT should have an overall plan identifying what systems will be used as the source of critical data and how that data will be managed, where data will be stored, how it will be validated, and identify the compliance and retention requirements.

With goals, functional requirements and technology needs have been identified, the next step is to assess the available applications that align well with your defined needs. Be on the lookout for solutions that offer a complete pivot from your current process and see if they provide new perspective or capabilities you never considered, or they may just not be a good fit at this time.

With a short list of applications, it’s time to setup demonstrations and vendors evaluations. Again, IT should be involved with assessing the vendor provided systems are sufficiently secure and reliable, unfortunately this is often not considered until there are issues or breaches.

Once the best vendor and application solution has been selected through demonstrations and reference checks, the next step is to plan for implementation. This involves developing a plan with the vendor for installing and configuring the application, migrating data, integrating with other systems, and training employees on how to use it. It is important to involve IT staff in the implementation process to ensure that the application is properly configured and integrated with existing systems and properly monitored. Before rolling out the application to all users, it is important to test it thoroughly to ensure that it is functioning as expected. This involves testing all features and processes and integration points with other systems.

It is important to keep stakeholders informed of the progress of the implementation and to address any concerns or issues that arise. This can help ensure a smooth transition and increase buy-in from employees. We typically build and follow a formal communication plan to ensure status and challenges are well communicated.

Once implemented and running, it is valuable to measure the effectiveness of the application, did it meet the original objectives. This can help identify areas for improvement and can help ensure that the application is providing a positive return on investment.

Wrapping up, by following proven processes and engaging the right resources to assist or lead the effort, organizations of all sizes can benefit from a periodic review and refresh of applications to ensure they are effective and provide the organization the intended value.
