13. Mineral insulated cables and their terminations with a rated voltage not exceeding 750V to BS EN 60702-I
14. Rigid and flexible cables of rated voltages UO/U up to and including 450/750 V a.c., used in power
installations and with domestic and industrial appliances and equipment to BS EN 50525
Cables shall be drawn in to conduits direct from the reels and cable which has become kinked, twisted or
damaged in any way shall be rejected. The installation shall be wired in the loop in system. That is, wiring shall
terminate at definite points and no intermediate connections shall be permitted.
The Contractor shall provide all the nesessary trays, conduits, supports and cable trunking, glands, end boxes,
clamps, compounds, specialist tools, etc., necessary to install, terminate and connect the cables in accordance
with good engineering practice. All cable shall be of copper conductor type.
The Contactor shall be responsible for the off loading and handling of the cables on site and shall ensure that
cables are new and delivered to site on new drum and properly protected against mechanical damage and loss
with manufacturer's seal still intact. Partly used drums of cable which has already been used elsewhere shall not
be acceptable unless special approval is given by the Engineer in writing. The type of the cable (PVC/PVC-Cu,
XPLE/PVC-Cu or PVC-Cu) shall be strictly as per the type mentioned in the drawings.
The current carrying capacity of each cable shall be in accordance with I.E.E Regulations and latest amendments
and shall be limited to the specified voltage drop. Colour of the cables shall follow the new colour code according
to latest IEE Wiring Regulations.
