W104 | Low Voltage MCCs

April 29, 2021 @ 11:00 am - 12:00 pm EDT


This course will discuss how to protect your workers that can be exposed to Arc Flash hazards and current protection objectives for working with MCCS. An ‘Arc Resistant’ low voltage MCC will be introduced with a focus on how a ‘Device Limited’ Arc Resistant LV MCC can provide maximum safety benefits to the operators.

Register for this Course Today!

  1. When you sign up for this W104 class you will also be registered for W101 and W120.
  2. Attending all three is not mandatory, but each class builds from the previous one.
  3. If you have previously attended the W101 course you may attend to refresh yourself on the material for the next courses, but it is not required to attend again.
  4. For further questions contact Brian Logan at 804-915-4704 or Brian.Logan@eeco-net.com

Hear From The Best In The Business

Speaker - Mike Lang, Principal Field Engineer at Mersen

Mike has participated in over 1,000 arc flash tests in Mersen’s high power test lab as leader of the Mersen arc flash team. He has co-authored several prize-winning IEEE papers on arc flash including papers at the 2006 PCIC Conference, the 2008 PPIC Conference, and the 2016 PPIC Conference. He was also awarded the 2011 I&CPS Ralph H. Lee Department Prize Paper Award for his work on 208V arc flash research. He recently received the 2018 Technical Award for Excellence in Prevention Through Design by the Electrical Safety Committee of the IEEE Industrial Application Society.

Mike is currently co-chairman of the IEEE/NFPA Collaboration on Arc Flash Research effort and has served as a member of the Research, Test and Planning Committee and on the Technical Advisory Committee as part of Mersen’s Platinum sponsorship of the Collaborations research. Mike is an active member of the IEEE 1584 Working Group.
