smoke and corrosive gases when affected by fire to BS 7211

Specification for 300/500V fire resistant electric cables having low emission of smoke and corrosive gases when

affected by fire - Part I - Multi core cables to BS 7629-I

9.  600/I000V annored fire resistant electric cables having thermosetting insulation and low emission of smoke

and corrosive gases when affected by fire BS 7846.

10. Thermosetting insulated, non-armoured cables with a voltage of 600/1 000 V, for fixed installations to BS

7889:2012

11. Flexible cords rated up to 4501750V for use with appliances and equipment intended for industrial and

similar environments to BS 7919

12. 300/500V screened electric cables having low emission of smoke and corrosive gases when affected by fire,

for use in walls, partitions and building voids (Multi core cables) to BS 8436

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.
