Perhaps you can shed some light on this condition for TNCS systems in the Irish Rules. I can only see that as RE decreases RB becomes more onerous but to be honest I am not really getting the essence.
What we call the DNO earth is referred to as the DSO earth in figure 8.
So in for a penny, in for a pound!
If the DSO earth is 20 ohms the maximum consumer installation earth rod impedance is on the face of it is 5.26 ohms, but it is actually referring to the extraneous-parts, not the rod.
