Harnessing the Power of Wind

Posted by mwearley Employee Nov 24, 2015


Harnessing the power of wind is an intriguing idea, but far from new. Wind power was used to propel ships to the new world in 1492. With conventional fossil fueled generators, after you buy the generator, you have to buy the fuel. The constant need to buy fuel doesn’t end until the machine is finally taken out of service.

Individual wind turbines and larger wind farms are springing up in a lot of places. Unlike their fossil fueled counterpart, there is no fuel to purchase. What a great concept, no fuel bill! No pollution! It isn’t quite that simple. There are a lot of factors that must be considered when evaluating the viability of a new wind project. Here are a couple of interesting documents posted online that provide some interesting insights on what must be considered for a wind project:

Wild Life considerations

The American Electrical Manufacturers Association formed on August 16, 1905 consisting of just (12) New York area electrical manufacturers.  The organization changed its name to the Electrical Manufacturers Club (EMC) in October 1905.  The EMC exists to this very day.



On June 3, 1908 a group of electric motor manufacturers formed the American Association of Electric Motor Manufacturers to promote motor design standards.  The organization expanded its membership to include generator manufacturers and reorganized as the Electric Power Club (EPC) on November 2, 1910. 



The Associated Manufacturers of Electrical Supplies (AMES) formed on May 9, 1915 with a goal of developing uniform performance standards and cost accounting in manufacturing and distribution.



Recognizing a common mission, the AMES, EMC, and EPC came together in 1922 to form the Electrical Manufacturers Council with each organization remaining a separate entity. 



On September 1, 1926 the AMES & EPC agreed to consolidate their memberships into a single organization, the National Electrical Manufacturers Association (NEMA).  Today, NEMA represents over 400 member companies that employ 400,000 American workers at over 7,000 American facilities.  Domestic production exceeds $117 billion dollars a year.



NEMA publishes over 550 product standards.  This includes 228 NEMA standards, 40 ANSI standards, 229 American National Standards, and 81 CANENA/IEC Harmonized Product Safety Standards.  NEMA participates on over 2,500 meetings per year.

The Passing of a Legend – John D Minick | NEMA Currents



The electrical industry is mourning the death of former NEMA Field Representative John Minick who passed away on October 8, 2015.  He was 72 years-old.  John was a nationally recognized electrical code expert and a consummate advocate of the electrical industry.  Many generations of electrical professionals have been guided and mentored by John’s immense knowledge of the electrical code and electrical code history.



My relationship with John was series of remarkable coincidences.  The first seminar I attended as a member of the IAEI was a code workshop instructed by John Minick and Mark Ode.  What an amazing experience.  Not only was John’s total recall of the NEC incredibly impressive, but his ability to explain the code in a manner both technical and understandable made learning from John effortless.  John knew everyone in attendance on a first name basis and once he met you for the first time, he never forgot who you were, who you worked for, and where you first met.  It was this personal touch that endeared him to so many in the electrical industry.  As I sat there in class, I clearly remember thinking that I wanted to be like these guys one day.  I wanted to know the code and be able to present the code at this level of expertise.  I was deeply inspired.



Several years after this first meeting, I had the opportunity to attend my first IAEI Southern Section Meeting.  It was during this event where the second coincidence occurred.  On the night of the banquet, John was inducted into the prestigious IAEI Golden Roadrunners Club.  I felt so fortunate to be in attendance to witness this great moment in John’s career.  Experiencing this event reaffirmed my commitment to the electrical industry and my desire to be an educator and advocate.



On May 19th 2014, I found myself on the 9th floor of Arlington Tower in Rosslyn, Virginia beginning my first day as the new NEMA Southern Region Field Representative.  I could hardly believe it.  It was a dream come true.  It has been an honor and privilege for me to continue the legacy established by John Minick and the other NEMA Field Representatives.  Everywhere I go and every event I attend, at least one person shares with me a John Minick story.  They are usually funny or emotional, and clearly had an impact on the person telling me the story.  What a gift.



I believe we have all been inspired by John and will continue to be inspired by the knowledge and education he has left us with.



Rest in peace John Minick.  You will be missed but never forgotten.


New NEC Article

Posted by mcloutier Employee Aug 18, 2015

Please join the Electrical Section for this panel discussion on Wednesday at 11:00-12:30 in Room 502 ab. The panel will consist of 13 presenters who will present a variety of industry perspectives on how a broad spectrum of constituents have worked together for 118 years to develop electrical safety requirements. This fast-paced presentation will demonstrate how important it is that industry work together to identify hazards and to update the requirements so that the code is able to address the ever changing electrical industry. The presentation will point out how important it is that jurisdictions adopt the latest edition of the code.

John discussed UL standards for safety evaluation of PV equipment. He also reported on recent research performed by UL, including hazards that first responders may face. He also addressed current requirements for rapid shutdown. His PowerPoint presentation is packed with useful information. It will be available through the NFPA Conference & Expo mobile app.

John Kovacik chaired the NEC DC task group. For the current cycle, the task group developed three proposed new articles for consideration by CMP 13. The new articles are:

  • Article 706-Energy Storage
  • Article 710-Microgrids
  • Article 712-DC Microgrids

CMP 13 created first revisions based on proposed new Articles 706 and 712. CMP 13 resolved the public input for Article 710. However, CMP 4 developed a first revision for Article 705 that would capture many of the requirements for stand-alone and intentionally islanded systems.


John's power point presentation is packed with useful information on the task group's work and the panels' disposition of the work. His presentation is now available in the mobile app for the 2015 Conference and Expo.

Later to day, come to session T55 on Tuesday at 2:00-3:00 to review current NFPA 70E requirements and hear about the research findings related to electrical injuries.  Room S502ab.

NFPA 3 & 4 Office Hours

Posted by jwilmot Employee Jun 20, 2015

Check out this edition of Office Hours which provides an overview of the concepts of Commissioning an Integrated System Testing in accordance with NFPA 3 and 4.

A requirement mandating receptacle outlets be installed in meeting rooms may be included in the 2017 NEC. Code Making Panel 2 has developed a first revision that would require a minimum number of receptacle outlets to be installed in meeting rooms intended for the
gathering of seated occupants for such purposes as conferences, deliberations, or similar purposes, where portable electronic equipment such as computers, projectors, or similar equipment is likely to be used.
The addition of this new section addresses safety concerns relating to inadequate access to electrical power in meeting rooms.

A tightening torque requirement may be included in the 2017 NEC. Code Making Panel 1 has developed a first revision that would require a calibrated torque tool to be used to achieve the indicated torque value, indicated as a numeric value on equipment or in the installation instructions provided by the manufacturer, unless the equipment manufacturer has provided installation instructions for an alternative method of achieving the required torque. Use of proper torque tools is essential to verify that terminations are properly made and the equipment will function properly
throughout its life cycle. Testing has shown that installers use the wrong torque values in up to 75% of installations unless a torque measuring tool is used.

Most conversations I have regarding electrical safety in the workplace relate to Personal Protective Equipment (PPE). And I usually begin my side of the conversation with two questions: Is the energized work justified? Have you preformed a risk assessment?  The purpose of NFPA 70E is to provide a practical, safe workplace for employees, relative to the hazards arising from the use of electricity. By the use of the hierarchy of safety controls, as explained in NFPA 70E, Informative Annex P, the risks associated with the use of electricity in the workplace can be reduce to an acceptable level. The first control is “Elimination”. Creating an electrically safe work condition, as identified and defined in NFPA 70E, Article 120, is a form of elimination. By creating an electrically safe work condition the risks are reduced to an acceptable level and the potential inherent electrical hazards have been effectively eliminated. It is important to keep in mind that the use of PPE is considered the least effective of the safety controls and the last line of defense before an event happens. NFPA 70E is all about practical, accomplishable electrical safety and about the worker going home safe at the end of the day to his or her family. For more information on the Hierarchy of Safety Controls, See Informative Annex P.


Be Safe!
