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.

    I have it in mind that Uoc  is 240 volts despite the declared voltage being 230 volts.


    20 ohms would actually be high for RB and the lower it is the lower RE can be.
