So this is the resistance between the neutral incomer to a EV feeder pillar from the TNCS intake and the disconnected end of the TT earth electrode also at the pillar. 28.5 ohms on the low resistance ohmmeter scale.
Just a thought as I always avoid doing resistance/continuity on non-isolated conductors - might the voltage difference between the N/PEN conductor and the electrode be influencing the reading? (The N potentially being affected by v.d. on the N from any loads connected to the same transformer)
