Multiple Earthed Neutral (MEN) System
Interconnection and earthing of exposed conductive parts and the neutral are mandatory Interruption for the first fault using overcurrent protection (circuit-breakers or fuses) Operating technique: interruption for the first insulation fault... Equipment earthing is a connection done through a metal link between the body of any electrical appliance, or neutral point, as the case may be, to the deeper ground soil. The metal link is normally of MS flat, CI flat, GI wire which should be penetrated to the ground earth grid.

- It has to be kept away from other earthing pits such as electrical power earthing and lightning protection earthing. Other Important Points to Clean Earthing or Grounding System. Clean earth grounding system shall not be connected to any other earthing or grounding system. Clean earth grounding cables shall not be run parallel with other grounding cables or power cables. Clean earth …
- Earthing in electrical network. The main reason for doing earthing in electrical network is for the safety. When all metallic parts in electrical equipment are grounded then if the insulation inside the equipment fails there are no dangerous voltages present in the equipment case.
- System not connected with the earth (highimpedance earth or isolated earth), all exposedconductive part connect to earth• Neutral is totally isolated• Infinity earth fault loop impedance• Deemed less chance of electric shock• Many disadvantages: phase current equal to livevoltage (because of floating Neutral); no zeroreference, may cause arcing when earth fault occurs;to small of earth
