    Potential circuit faults - RCD/ Megger

    Hi folks, In your opinion, do you think there would ever be a situation where an RCD (presuming it worked) would not pick up a problem that a megger test would? i.e an RCD would trip if there was ever a L-E, N-E or L-N fault

    Rig for demonstrating 'faults'

    Purely for training purposes only, using an isolating tx, could you effectively recreate the three earthing systems sufficiently to be able to trick a Martindale into giving false display for N/E faults?
