Metallic casings, pipes and conduits must be grounded, and when
fitted with joints these must be mechanically and electrically
grounded.
Cable connections
All cable connections are shown on the applicable cable plan and
interconnection diagrams.
Where the cable plan shows cable connections outside an
equipment box outline, the connections are to be made to a plug or
socket which suits the plug or socket on that particular item of
equipment.
Where two cables are connected in series via a junction box or
terminal block, the screens of both cables must be connected
together but not grounded.
Cable terminations
Care must be taken to ensure that the correct terminations are used
for all cable conductors, especially those that are to be connected
to terminal blocks. In this case, crimped sleeve-terminations must
be fitted to prevent the conductor core from fraying and making a
bad connection with the terminal block. It is also of the utmost
importance that where crimped terminations are used, the correct
size of crimp and crimping tool are used. In addition, each cable
conductor must have a minimum of 15 cm slack (service loop) left
before its termination is fitted.
Cable identification
Cable identification codes corresponding to the cable number
shown in the cable plan must be attached to each of the external
cables. These identification codes should be positioned on the
cable in such a way that they are readily visible after all panels have
been fitted. In addition, each cable conductor should be marked
with the terminal board number or socket to which it is connected.
