About twenty times each year, I am consulted on accidents involving our electric power delivery system. Most of them are accidents involving property damage.
One of our primary responsibilities in the electrical trade is to select electrical conductors, and one of the primary responsibilities of electrical inspectors is to judge those selection decisions properly.
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.”
Electrical inspection processes and techniques differ and often are dictated by construction conditions. Using the NEC Electrical Toolkit is a guide to help out.
Renovating those older systems adds flexibility through modern wiring practice and increases safety.
