What is an arc flash?

An Arc Flash is the result of a quick release of energy due to an arcing fault between a phase bus bar and another phase bus bar, neutral or a ground.

During an arc fault the air acts as the conductor. Arc faults are generally limited to systems where the bus voltage is in excess of 120 volts. Lower voltage levels usually will not sustain an arc. An arc fault is similar to the arc obtained during electric welding and the fault has to be manually started by something creating the path of conduction or a failure such as a breakdown in insulation.

why should arc flash concern me?

The primary reason to be concerned with arc flash is for the safety of the personnel. Short circuits and arc faults are very dangerous and may be potentially fatal to personnel. Exposure to an arc flash frequently results in a variety of serious injuries such as severe burns, damaged eyesight, ruptured eardrums, collapsed lungs, psychological trauma and in some cases - death. Arc flash hazard analysis is required to determine the risk to personnel, to warn them about hazards, and to instruct them as to what kind of personal protective equipment they must wear.

What is included in an Arc Flash Study?

-Updated One-Line Drawings
-Labels for all switchgear, panels, and disconnects
-Arc flash Risk Assessment report containing:

  • Risk Assessment Report
  • Coordination Study
  • Database Report (List of all Equipment)
  • Recommendations
