     1        A.  Yes, they are on a different circuit to the grills but
     2        they are -- they do have RCD cover.
     3
     4   Q.   The way you would, in your thing, notice that they had
     5        tripped out would be that there would be a clicking sound?
     6        A.  From the chicken vat.
     7
     8   Q.   From the chicken vat?
     9        A.  You would again get a flashing light on the manager's
    10        panel.  All the displays and banks of lights on the friers
    11        would go off; the shortening of the fat would cease to
    12        bubble and make crackling sounds like it normally does when
    13        it is being heated, and there would be just the large
    14        whoosh of air from the HVAC system, which is a heating and
    15        ventilation system above the extracts, and then there would
    16        be a large clicking sound from the extracts.
    17
    18   Q.   The HVAC system, that was not affected by the RCD system,
    19        was it?
    20        A.  Yes, it was.  It is on the same circuit.  It is on the
    21        extract circuit for the kitchen.  If the kitchen extracts
    22        go down, they are the part of the HVAC which remove all the
    23        fumes from the kitchen; then the grill -- the frier will go
    24        off and similarly, if the frier goes off, it is linked to
    25        the HVAC system so the extracts will go off.
    26
    27   Q.   The RCD system that you had at that time, did different
    28        areas of the kitchen, which is what we are talking about,
    29        sometimes cut out rather than the entire kitchen?
    30        A.  No, but they do now because at the time we just had one
    31        control board for every piece of equipment in the kitchen,
    32        which meant that as soon as it clicked out that is why we
    33        had to go upstairs and start plugging individual pieces of
    34        equipment back in.  We now have an RCD separate circuit for
    35        different areas of the kitchen.
    36
    37   Q.   So every single piece of electrical equipment, including
    38        the HVAC system ---
    39        A.  Would have to be reset.
    40
    41   Q.   -- would have gone out when it tripped out?
    42        A.  Absolutely.
    43
    44   Q.   The RCD?
    45        A.  The HVAC itself would have stayed on -- the air
    46        conditioning part of it would have stayed on in the
    47        restaurant, but the extracts, that is the part that
    48        specifically removes the fumes and the smell from the
    49        kitchen would have gone off.
    50 
    51   Q.   How many items of equipment then, just approximately, in 
    52        total would there be that would be linked up with the RCD 
    53        circuit?
    54        A.  What, in the whole kitchen?
    55
    56   Q.   Yes, just approximately.  Are we talking about 20, 30?
    57        A.  We are probably talking 15 to 20 pieces of equipment,
    58        yes, including the freezers, yes.

    60   MR. JUSTICE BELL:  You dropped your voice at the end of that
