Hi Sir,
For Earthing Grid installation, NFPA 780 requires minimum of 460mm burial below grade. If the top surface of the massive pile cap concrete, 1200mm thick, is 600mm below grade level, is the installation of lateral earth grid conductor directly above the pile cap concrete allowed?. What Standards can I refer to?
Regards and hope to hear from you on my query.
