Many working in the electrical industry are concerned with and dedicated to safe electrical system design, installation, and use.
Electrical hazards, such as arc-flash hazards, can be extremely damaging to equipment and, more importantly, to people.
To insure that electric supply facilities comply with the rules of the National Electrical Safety Code (NESC), Rule 214A 2 states, "Lines and equipment shall be inspected at such intervals as experience has shown to be necessary.”
An arc flash is a potentially very hazardous event, in which the heat energy alone can cause ignition of clothing and extensive severe burns.
