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.
During your career as an electrical inspector, have you ever received a shock while inspecting? Have you ever accidentally faulted a circuit between phases or to ground?
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.”
