The latest revision (2023) introduced several updates:
While the specific resistance target depends on the nature of the installation (LV vs. HV), a common rule of thumb for standard low-voltage consumer installations is to achieve an earth electrode resistance of for substations, and generally under 10 Ohms for standard commercial distribution, though lower is always preferred to ensure rapid protective device operation.
