     1        RCDs.  If it carried on working and it carried on working,
     2        you would make a check of the grills; you would make sure
     3        that they actually reached the appropriate temperature and
     4        then carry on cooking.
     5
     6   MR. JUSTICE BELL:  What was the situation that occurred then?
     7        Was it that you reset the RCD?  Was that just putting down
     8        the switch?
     9        A.  It is literally, you walk up to the (indecipherable),
    10        and you would see which light was flashing and you would
    11        press the reset button.  After unplugging the equipment
    12        downstairs, you would then plug the equipment back in piece
    13        by piece.  If there was a problem with a piece of
    14        equipment, it would make the RCD trip out again.
    15
    16   Q.   So you unplug the equipment on that circuit?
    17        A.  That is right, you would then reset -----
    18
    19   Q.   Let me just make a note of this.  Press the reset button?
    20        A.  You would then go back downstairs and plug in one piece
    21        of equipment at a time.
    22
    23   Q.   If it tripped again, that would ---
    24        A.  Indicate.
    25
    26   Q.   -- be an indication that there was a fault in that set of
    27        equipment?
    28        A.  That is right, and you would then take the appropriate
    29        action, either removing that piece of equipment or calling
    30        the appropriate service engineer.
    31
    32   MR. JUSTICE BELL:  I think -- either you do it or I will -- you
    33        want to ask about the situation, do you, when the RCD
    34        system was bypassed?
    35
    36   MR. MORRIS:  Yes.  (To the witness):  You have said in your
    37        statement that the Managers would authorise the trip switch
    38        to be removed temporarily?
    39        A.  That is right.  You would follow the procedure I have
    40        detailed and then, if it became obvious that there was no
    41        problem with a piece of equipment, i.e. you plugged all the
    42        equipment back in and the RCD has not tripped again, the
    43        first few times it has happened we phoned the service
    44        engineers anyway.  Then Clayton Construction informed us
    45        that after following those checks, as long as the equipment
    46        worked properly, that it was the RCD, we had to make a log
    47        of the RCD fault and then trip it out and then remove the
    48        circuit and rely on the individual fuses on each piece of
    49        equipment to work.
    50 
    51   MR. MORRIS:  So you would not have to consult with Clayton 
    52        Construction each time it tripped out?  It was just at the 
    53        beginning of that process?
    54        A.  No, but we would consult them on a weekly basis and
    55        they would want to know on a weekly basis how many times it
    56        had tripped out, and when it had tripped out, and if there
    57        are any times when we had to completely remove the RCD
    58        cover, then we had to phone them immediately and they had
    59        to come in and they would place the part that I think was,
    60        effectively, a fuse inside.
