At what distance from the foundation can grounding be done?
At what distance from the foundation of a private house is a ground loop necessary?
Hello! According to PUE 1.7.90 (Chapter 1.7) the distance should be 0.8-1 meters, but these are recommendations for networks with effectively grounded neutral.
In the section on dead-grounded neutral (your case) in section 1.7.100, it was possible to find information that the foundation of the building itself can be used as an earthing switch ...
Therefore, do it at a distance specified in section 1.7.90.
