ELECTRICITY SUPPLY REGULATIONS - REGULATION 18

Precautions to be taken when bare conductors are used

(1) Where the conductors of electric lines placed in any conduit are not
continuously covered with insulating material, they shall be secured in
position, and no unfixed uninsulated material of a conducting nature shall be
contained in the conduit. No such conductor shall be at a pressure exceeding
300 volts from earth.

(2) Adequate precautions shall be taken to ensure that no accumulation of
water shall take place in any part of the conduit and to prevent any dangerous
access of moisture to the conductors or the insulators.

(3) The insulators of any such electric line shall be so disposed that they
can be readily inspected; but this requirement shall not apply to any such
insulators which before 2 December 1921, were not required by any regulation
then in force to be so capable of ready inspection.
