What is difference between system grounding and equipment grounding? System grounding is done by connecting a conductor of a circuit to  the earth to keep the voltage stabilized. Equipment grounding is  when all metal frames of the equipment â¦and conductors are grounded  by a permanent connection.
A chassis ground is a connection to the main chassis of a piece of electronic or electrical equipment. In older appliances and in desktop computers, this is a metal plate, usually copper or aluminum. In some modern equipment, it is a foil run on the main printed circuit board, usually running around the periphery.n earth ground usually consists of a ground rod (or a set of ground rods) driven into the soil. At sea, the salt water forms a good earth ground if a corrosion-resistant metal plate having large surface area (such as the hull or keel) is placed in contact with it.
