Electrical Arc Flash Hazard Analysis

Changes to the 2005 National Electric Code (NEC) require Arc Flash Warning Labels to be installed on certain electrical equipment in industrial facilities. NFPA 70E "Standard for Electrical Safety in the Workplace" - 2009 edition and IEEE 1584 provide guidelines for conducting hazard/risk assessments to determine Arc Flash levels at each panel in the distribution system.

We have successfully performed many Arc Flash Hazard Analyses and Power Distribution System Studies at large Fortune 500 industrial facilities throughout the United States. As part of our standard services we always make recommendations to reduce Arc Flash levels where possible.  In most cases, by changing out fuses or circuit breaker trip units, or by modifying trip settings, we are able to reduce the Arc Flash Hazard levels at Motor Control Centers or Panels from HRC #3 down to HRC #0 or HRC #1.

We utilize computer modeling software ESA, Inc. EasyPower and SKM Analysis Power Tools to model the power distribution system. We base our calculations on NFPA 70E and IEEE 1584 standards to determine Incident Energy Levels (cal/cm2), Flash Boundaries and Personal Protective Equipment (PPE) Ratings. In addition, we print custom high quality Brady polyester warning labels and aluminum signs.
