LV neutral grounding in IEC standards
LV neutral grounding in IEC standards
(OP)
Hello,
In large plants we usually design the LV neutral grounding as TN-S, but do not distribute the "protection cable" with the phases and neutral cables to some loads. We do join does loads through a cable that we extract from the ground mesh.
I was wondering if in IEC standards, there is any "must have" for the distribution of the "protection cable".
Thanks.

I do not think there is a Standard that shows as mandatory using 5 wire cables(or 3 wire in case of 1phase loads).
You can use 3p+N cables, and connect PE from grounding system of building, with steel band.
