At one time, it was acceptable to bond an external (radio) earth to the incoming main earth terminal via suitably rated cable (10mm2 was it?) in a PME installation. Possibly via an earth line choke (several loops through some very large toroids) to isolate RF noise on a dirty mains earth.
Is that still acceptable practice or have the regulations changed again?
