Rule TOC
28 · Accidental charging: (1) The owners of all circuits and apparatus shall so arrange them that there shall be no danger of any part thereof becoming accidentally charged to any voltage beyond the limits of voltage for which they are intended_ (2) Where alternating current and direct current circuits are installed on the same box o support, they shall be so arranged and protected that they shall not come into contact with each other_ 29. Provisions applicable to protective equipment 1) Fire buckets filled with clean dry sand and ready for immediate use for extinguishing fires, in addition to fire extinguishers suitable for dealing with fires, shall be conspicuously marked and kept in all generating stations, enclosed substations and enclosed switching-stations in convenient location.
35 · Precautions against leakage before connection (1) The supplier shall not connect its works with the apparatus in the premises of any applicant seeking supply unless the supplier is satisfied that at the time of making the connection cause leakage from that installation or apparatus of magnitude detrimental to safety which shall be checked by measuring the installation'$ O apparatus insulation resistance as stipulated in the relevant standards_
8 · Failures of any 220 kV and above voltage level transformer; reactor and transmission line towers shall be reported by the owner of electrical installation, within forty eight hours of the occurrence of the failure, to the Authority and the reasons for failure and measures to be taken to avoid recurrence of failure shall be sent to the Authority within one month of the occurrence in the forms provided in Schedule VII: Provided that in case of mines and oil-fields, the failure of 10 MVA or above transformers shall be reported to Electrical Inspector of mines 49_ Precautions to be taken against excess leakage in case of metal sheathed electric supply lines. The following precautions shall be taken in case of electric supply lines other than overhead lines, for use at voltage exceeding 650 V, namely the conductors of the cable except the cable with thermoplastic or cross linked polyethylene, insulation without any metallic screen or armour shall be enclosed in metal sheathing which shall be electrically continuous and connected with earth_ and the conductivity of the metal sheathing shall be maintained and reasonable
58 · Joints: (1) No conductor or earthwire of an overhead line shall have more than one joint in a span: Provided that there shall be no joints in the conductor or earthwire in a span of crossing over the highways, expressways and railway lines (2) The joint between conductors O earthwires of overhead lines shall be mechanically and electrically secured
