I think you did not understand my question.If I provide overcurrent protection at nutral in TNS system than it will give protection from overcurrent condition for phase to ground fault. Same way if we apply overcurrent protection in neutral of TNC it will protect the system from phase to ground as well as from phase to equipment body fault.Then why it is mentioned (only mentioned not explained) in all documents whose details you have mentioned that O.C. Protection device is not permitted at neutral of TNC earthing system? I raised any query in this foram when I didnt get a suitable explaination anywhere.
