When we have earthing mesh or underground earthing network
in industrial plants, weather we have NT-S or NT-C-S kind
of earthing system, so eventually weather we must use 4 or
5 wire in 400 volt level (For example 3×150+70 mm2 or 5×150
mm2) in this connection I would like to know exactly the
paragraph of IEC or IEEE number
