Understanding Electrical Grounding.
The electrical grounding system is a backup path for electric current to flow back to the power source in case of a fault. Nature Of Electric Current Flow. Electric Current flows from a power source through live wires to a load. The current then returns back to the power source through the neutral wire. The same is true for AC and DC power sources. current always returns to the power source. It is important to know that electric current always tends to flow through the path of lowest resistance. Power sources include 1) Batteries - electrons flow from negative to load returns through positive. 2) Transformers - current flows from phase to load returns through neutral. 3) Alternators - current flows from phase to load returns through neutral. Short Circuit A complete and healthy circuit loop is formed when electric current flows from the source, to the load and back to the source through the neutral. This is the normal path in which electricity is expected to
