    Domestic Find electrician to trace earth leakage

    OK, so this is a follow-on to my thread about unsatisfactory EICR. There is a big inconsistency in that the EICR reports all the L-E IR as >100 Megs, but the inspector also comments about earth leakage in two ring mans and one lighting circuit. This seems to be stopping me from replacing the...
