the old copper strip is attached to the wall of the sump with a small screw or nut some one or two inches below the attachment of all wires of the bonding. Does this screw serve for fastening only or does it also provide an electrical connection to a hidden part of the bonding system?
My idea is to fix the new stronger copper strip higher to get more distance between max. sump water level and junction point of wiring and copper strip.
