Understanding NEC 240.67 2017, Arc Energy Reduction for Fuses

Understanding how to apply, model, and evaluate various arc flash reduction strategies is an important skill.  Proper modeling and evaluation of the results are key components to selecting appropriate arc flash reduction techniques and selecting the setting(s) to optimize application method(s). This session, presented by Ryan Bergeron at GE, will provide you with an understanding of how to model two of the methods cited in the new NEC 2017 Article 240.67 for Fuses 1200A or higher – (B) 0.07 seconds or less at the available arcing current and (B)(2) Maintenance Switching – for a low voltage system using EasyPower® analysis software.
