    Earthing with solid rock below surface - burying tape for lightning earth

    A quick search for earth tape didn't come up with much, though this thread was of interest. I'll start by mentioning that I've led a sheltered life and only ever dealt with PME (TN-C-S) so never had to deal with earth rods. At our church, we've had an inspection of the lightning protection...
