    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

    EICR code - potential load on lighting circuit more than MCB rating

    I'm writing up an EICR. On one of the lighting circuits the potential load is theoretically about 1300W on a 5A BS3871 breaker.
