Is caisson grounding safe?
Good day. Is this grounding scheme possible and will it work: a corner of 50 by 50 by 2 meters is clogged into the ground from it a 1.5 m bus is welded to the caisson (size 1 m per 1 m and the depth of the caisson 2 m). The caisson was made under the well, the pipe goes to a depth of about 15 m, the well is working.
P.S. Explain whether it will be safe, if not difficult, describe the possible negative consequences.

Hello! Earthing using a caisson is sometimes used by hosts. It is of course better to organize a separate circuit, however, this option is acceptable. The negative consequences are corrosion by currents, as a result of which the well life is reduced.
