705--1 No size smaller than 16/0.20mm (0.50 mm²) shall be used. Size of flexible cords and cables shall be such
that the current normally carried by them shall not exceed the values shown in the appropriate table in Section 15.
705--2 Where apparatus requires to be earthed, flexible with earth core shall be used.
23
705--3 Flexible cords and cables shall be so connected to plugs or ceiling roses, etc., that the Brown or Black
sheathed conductor is connected to the phase, the Blue sheathed conductor to the neutral and the Green/Yellow
conductor to the earth .
705--4 Flexible cables and cords shall be so connected to portable or fixed apparatus, standard lamps, etc., that
the green/yellow conductor is connected to the frame of the apparatus and any single pole sw itches are so connected
that they break the phase conductor to the apparatus.
705--5 In all situations where flexible cables and cords are exposed to the risk of mechanical damage, they shall
as a minimum be of a type sheathed with rubber or PVC and where necessary shall also be armoured.
705--6 Where flexible cables and cords are normally exposed to the risk of damage due to high
temperatures, they shall be insulated with silicone rubber or other approved insulating materials.
705--7 Connections of flexible cords and cables to terminals of apparatus and accessories shall be made in a similar
manner to those of cables.
705--8 The current carrying capacities of flexible cables and cords and the maximum weight that they may carry
shall not exceed the values given in the appropriate table in Section 12.
705--9 All flexible cables and cords shall have the following identifications:
(a) Two core Brown Phase
Blue Neutral
(b) Three core
(c) Four or Five core
Brown or Black Phase
Blue Neutral
Green/Yellow Earth
Brown or Black Phase
Blue Neutral
Green/Yellow Earth
705--10 Flexible cables and cords shall be used only for the following purposes:
(a) as pendants
(b) as wiring of fixtures
(c) as connection of portable lamps or apparatus
(d) as lift travelling cables.
NOTE - In other special situations flexible cables may be employed after the prior approval of the M. E. W .
705--11 Flexible cables and cords shall not be used as a substitute for the fixed wiring.
