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.
Figure 1 is the schematic of an appliance without an equipment grounding conductor connected to the metal chassis. The appliance is sitting on a wood table, and therefore isolated from earth ground.The appliance is OFF, but a wire insulation fault has occurred before the switch.urthermore, there is usually considerable resistance between the appliance and earth ground. For example, the appliance may be sitting on a concrete slab. Figure 3 depicts the same appliance with an equipment grounding conductor connected to the metal chassis.
