### sec.195 Earthing electrodes The electrical engineering manager for an underground mine must ensure earthing electrodes installed for the underground electrical distribution system’s connection to earth are located at the surface of the mine. If the mine has more than 1 electrical distribution system, the mine’s safety and health management system must provide for the prospective touch voltage at the mine to be limited to a level necessary to achieve an acceptable level of risk. The electrical engineering manager must ensure the ohmic resistance of an earthing electrode assembly for the underground electrical distribution system is kept as low as practicable and does not exceed 1 ohm.
