Improving Electrical Safety With Short Circuit Protection

  • New incident energy equations in the 2018 edition of IEEE 1584 may provide different results than existing arc flash studies. Learn what “electrode configuration” means for the data collection step of your next analysis. Learn the new technique available to take advantage of the current limiting ability of modern day fuses.
  • Learn why NFPA70E dropped the 240V exception for arc flash analysis and what the change to IEEE1584-2018 will require.
  • Gain insight into what is meant by “exposed to the arc flash hazard” and who may be affected.
  • Do some of your circuits have incident energies greater than 1.2 cal/cm2 even when protected by dual element Class RK1 or J fuses? Or Class L. Learn why and what options you have to lower energies to “Category 0” Level.
  • Review a simple primary fuse change that can help lower energies to below “Category 3” PPE levels at substations that have incident energies much greater than 40 cal/cm2.
  • New information will be presented on coordination between fuses and upstream circuit breakers in the ‘short circuit’ region to address issues that can arise as settings of upstream devices are lowered to reduce arc energies.
  • Are your control panels compliant with NEC 110.10? NEC 409.22? Review some choices that ensure adequate ratings throughout the life of the panel.
  • Can your storeroom enhance your electrical safety program? Review a simple “5S” program to ensure safe fuse replacements.
