Base Earthing System is the earthing system which consists of conductors that are installed into base concrete by linking to construction irons. Generally 30x3 galvanized earthing tape is used as it is conductive. Galvanized conductive tape is installed into concrete vertically and is linked to construction irons in certain spans.
To complete the connections of the earthing system, connecting terminals are extracted from certain points to the outside. In addition to this, if there is outside lightning systems in the building, connecting terminals must be left to make the connection to the outside lightning earthing system. After that when the outside lightning system is installed, outside lightning earthing system and base earthing system are connected.
