Grounding systems are used to transfer unwanted or fault currents away from anything that could possibly be damaged by a sudden surge of power. They are not designed to carry or supply normal electricity through your home or building.
The National Electric Code (NEC) requires every home in the United States to be equipped with a grounding system. If lightning strikes, grounding systems carry the voltage to the cold water main and send it into the earth. A proper grounding system must include a clamping device and bonding strap. The bonding strap must be connected back to the conduit on the electrical grounding system; without this the electrical current can run back into the house.
The second most popular electrical grounding system found throughout the United States is called a driven ground rod. A driven ground rod is just what it sounds like – a copper-coated rod that is driven into the ground outside the building. It serves the same purpose as the in-home grounding system described above, but is only used under very high voltage situations such as a severe lightning strike.
To protect against ground faults, electricians will assess the building to determine which type of grounding system would be most appropriate. Different types of buildings and operations require different grounding systems. Each type of grounding system has a different set of advantages and disadvantages, so it is utterly important that you have these installed by a licensed technician who understands all the aspects of the grounding systems.
