    Question regarding to GFCI
        A GFCI protection is connected to the primary side of the isolation transformer. My question:  does GFCI sense and will trip, if the leakage is on the secondary side of the isolation transformer?

    The secondary side of a transformer will not trip the gfci.  Are you dealing with pool transformers?

    Agree with Dennis, the GFCI will not operate for leakage current on the secondary side.
