concentric cable) within a consumer’s premises, in an accessible position as
close as possible to the point of entry. Such cut-out shall be contained within
an adequately enclosed fire-proof receptacle:
Provided that where more than one consumer is supplied through a common
service-line, each such consumer who so requires shall be provided with an
independent cut-out at the point of junction to the common service.
41. Accessibility of bare conductors. Where bare conductors are used in a building the owners
of such conductors shall ensure that they are inaccessible without the aid of a
ladder or other special appliance and shall provide switches for rendering them
dead whenever necessary.
42. Handling of apparatus. Before any conductor or
apparatus is handled, adequate precautions shall be taken, by earthing or other
suitable means, to discharge electrically such conductor or apparatus, and any
adjacent conductor or apparatus if there is danger therefrom, and to prevent
any conductor or apparatus from being accidentally or inadvertently
electrically charged when persons are working thereon:
Provided that this Sub-rule shall not apply to the cleaning of commutators and
sliprings working at low or medium pressures,
43. Repairs to apparatus. No repair of any part of
any apparatus shall be effected while the part is live, except by an authorised
