Description
Summary:Recent discussions between governmental agencies, engineers, and standards/code making panels have raised the question of the appropriate type of grounding system conductor. What type of conductor should be used in grounding connections? What factors affect the life of grounding conductors? How should grounding conductors be sized? How do the current standards requirements affect the quality of the ground system? In many cases, the selection of the construction and material conductor to be used is considered a matter of preference. However, the proper selection of the conductor can enhance or degrade system reliability and performance. This is especially true in critical or high energy applications. The technical factors that go into the selection of a grounding conductor are discussed. Reliable criteria for the selection of the appropriate grounding conductor are developed and presented.
