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.
Earth in an electrical installation usually refers to ground. An equipment or electrical appliance has to have a ground wire to protect users from electrocution in case of electrical leakage.ost things on the surface of the earth are at the same electrical potential as the earth itself-if something (or someone) was not, an electrical current would flow to or from it to the earth until tthe potentials were equal. This can sometimes happen if you are insulated from the earth by, say, rubber shoes.
