715 BUNCHING AND SEGREGATION OF CONDUCTORS

715-1 Where conductors or bunches of conductors are protected by metallic sheathing, installed in metalic
conduits. trunking or ducts, the conductors of all phases and neutral, associated with any one circuit, shall be
included in the same sheath, conduit, trunking or duct.

715-2 Where conductors pass through the metallic case of any switch fuse, distribution board or other apparatus,
or through any structural steel of any building, etc., all phase conductors and the neutral associated with any
circuit shall pass through the same hole or aperture.

715-3 The dividing of the conductors of any circuit in such a manner that they induce magnetic fluxes or
electrical currents in their sheathing or adjacent or surrounding metal of any sort shall not be permitted.


715-4 Where 240 volt loads a re fed from a three phase and neutral distribution board no multi -gang s witch or
socket outlet box shall contain the wiring fed from more than one phase.

715-5 Not more than three lighting circuit or two socket circuits shall be bunched in the same conduit.

715-6 Where circuits are bunched proceeding from the distribution board and have separated they shall n ot be
brought back again into any common conduit.

715-7 Circuits fed from distinct sources of supply from different distribution boards or through separate isolators
shall not be bunched in one conduit.
