[No. 49

which may be upon a consumer’s premises, being maintained
in a safe condition and in all respects fit for supplying energy.

49. In delivering the energy to a consumer’s terminals the
    licensee shall exercise all due precautions so as to avoid risk
    of causing fire on the premises.

50. The maximum working-current in any conductor shall
    not exceed 1,000 amperes per square inch of section.

51. All electric lines and apparatus on a consumer’s pre-
    mises, excepting such parts as are required to be connected to
    earth, shall be highly insulated, and be suitable for the volt-
    age at which supply is being given. They shall be thoroughly
    protected against injury to the insulation and against the
    access of moisture, and any metal forming part of the electric
    circuit shall not, unless efficiently connected with earth, be
    exposed so that it can be touched. All electric lines shall be
    so fixed and protected as to prevent the possibility of elec-
    trical discharge to any adjacent metallic substance.

52. The licensee shall fix, where the service mains terminate
    on any premises, double-pole well-protected fuses of at least
    2 in. clear break. The consumer shall also place, as near to
    the entrance-fuses as may be practicable, double-pole main
    switches of ample carrying-capacity, well insulated, with
    quick break of sufficient clearance to prevent arcing.

53. The wiring shall be done from distributing-boards,
    which shall be of incombustible material. Suitable fuses on
    each pole fitted to engage in spring clips shall be placed on
    these boards, so that it shall be possible to disconnect any
    or all circuits from the supply. If double-pole switches are
    used on the distributing-board circuits, fuses need not then
    be of the type to engage in spring clips.

54. The covers of fuses, switches, and plugs should be of
    efficient porcelain or other incombustible non-conducting ma-
    terial, or of rigid metal lined with vitreous enamel or such-
    like substance. All metal parts liable to be touched must be
    effectively insulated from the electrical circuit.

55. There must be an approved porcelain bridge or other
    efficient insulation between the terminals of lamp-holders,
    and where lamp-holders are liable to be handled by persons
    making good earth contact they shall be provided with non-
    conducting covers. Not more than three amperes shall be
    controlled by each sub-switch.

56. The insulation of conductors used for interior wiring
    shall be of vulcanized rubber of not less than 600-megohms-
    per-mile grade, or of other approved material suitably pro-
    tected. Concentric conductors may be used, and their insu-
    lation resistance shall not be less than that required for
    separate conductors.

57. All arc lamps shall be so guarded as to prevent pieces
    of ignited carbon or broken glass falling from them, and shall
    not be used in situations where there is any danger of the
    presence of explosive dust or gas.

58. Arc lamps used in any street for public lighting shall
    be so fixed as not to be in any part at a less height than
    10 ft. from the ground.

59. Arc lamps used in any street for private lighting shall
    be so fixed as not to be in any part at a less height than
    8 ft. from the ground, and shall be so screened as to prevent
    risk of contact with persons.

60. Arc lamps must be insulated from earth and be fixed
    so that they cannot swing into contact with any substance,
    metallic or otherwise, that might connect them to earth.
    Resistances for the regulation of arc lamps, if exterior to the
    lamp, shall be mounted on incombustible bases, shall be so
    placed that they cannot by conduction or radiation set fire
    to any contiguous materials, and shall be of ample size to
    safely carry the maximum current that will normally flow
    through them. Each arc-lamp circuit shall be provided with
    a fuse on each pole. Interior arc lamps shall also be pro-
    vided with a switch on each circuit.

61. The frame of all motors shall be connected to an efficient
    earth by a copper conductor, which shall not be less than 0·023
    square inches in sectional area. All metal casings of switches,
    resistances, fuses, cables, and wires shall be efficiently earthed
    in a similar manner.

62. Every motor must be controlled by an efficient double-
    pole quick-break switch, suitable to prevent arcing, and con-
    veniently placed so that the person in charge of the motor
    can cut off wholly the supply from the motor, and all devices
    in connection therewith.

63. Efficient fuses or other automatic cut-out must be pro-
    vided to efficiently protect the conductors on each pole from
    excess of current.

64. Every precaution shall be taken in choosing positions
    for and in the wiring and setting-up of motors, and the neces-
    sary devices in connection therewith, so that there shall be
    no danger of fire being caused by their normal or abnormal
    action, or of shock being sustained in the ordinary handling
    thereof.

65. Terminals of motors supplied must be so guarded that
    they cannot be accidentally touched or short-circuited.

66. The insulation resistance of each motor-circuit, includ-
    ing all devices necessary for the working of the motor, shall
    be not less than 1 megohm to earth when all metal parts
    that are required to be connected to earth are so connected.

67. A printed notice shall be fixed in a conspicuous posi-
    tion at every motor and switchboard forbidding unauthorized
    persons to touch the motors or apparatus.

68. The licensee shall not connect the wires and fittings on
    a consumer’s premises with its mains, or, in the case of pre-
    mises already connected, continue the supply from its mains,
    unless it is reasonably satisfied that the requirements of this
    license, so far as applicable, are being complied with, that
    the wiring and fittings are suitable for the voltage at which
    supply is being given, and that the connection or continuance
    of supply would not cause a leakage from those wires and
    fittings exceeding one ten-thousandth part of the maximum
    supply current to the premises; and where the licensee de-
    clines to make such connection or to continue supply it shall
    serve upon the consumer a notice stating its reasons for so
    declining.

69. If the licensee is reasonably satisfied, after making all
    proper examination by testing or otherwise, that the wiring
    and fittings are not suitable for the voltage being employed,
    that a leakage exists at some part of a circuit of such extent
    as to be a source of danger, and that such leakage does not
    exist at any part of the circuit belonging to the licensee, or
    that any other requirements of this license, so far as they
    apply to the consumer’s premises, are not being complied
    with, then and in such case any officer of the licensee duly
    authorized by him in writing may, for the purpose of dis-
    covering whether the leakage exists at any part of a circuit
    within or upon any consumer’s premises, or whether the wiring
    is suitable and the general requirements of this license are
    complied with, by notice require the consumer, at some
    reasonable time after the service of the notice, to permit him
    to inspect and test the wires and fittings belonging to the
    consumer and forming part of the circuit.

If on such testing and inspection the officer discovers a
leakage from the consumer’s wires exceeding one ten-thou-
sandth part of the maximum supply current to the premises,
or that the requirements of this license are not properly con-
formed to, or if the consumer does not give all due facilities
for inspection and testing, the licensee shall forthwith dis-
continue the supply of energy to the premises in question,
giving immediate notice of the discontinuance to the con-
sumer, and shall not recommence the supply until he is
reasonably satisfied that the cause of leakage has been
remedied and that the installation is in conformity with these
conditions.

70. If any consumer is dissatisfied with the action of the
    licensee in refusing to give, or in discontinuing, or in not
    recommending the supply of energy to his premises, the
    wires and fittings of that consumer may, on his application
    to the Minister, and on payment of the cost of such inspec-
    tion, be inspected and be tested for the existence of leakage
    by the Inspecting Engineer.

This provision shall be indorsed on every notice given
under the provisions of either of the two last preceding clauses
hereof.

71. From the time when the licensee commences to supply
    energy through any distributing-main, and during the con-
    tinuance of this license, he shall maintain during such portion
    of each day as he from time to time determines, sufficient
    power for the use of all the consumers for the time being
    entitled to be supplied from such main; provided that, for
    any purposes connected with the efficient working of the
    undertaking, the Minister may give permission to the licensee
    to discontinue the supply at such intervals and for such
    periods as he thinks expedient. When the supply is so dis-
    continued, public notice shall be given, when practicable, of
    such discontinuance, and of the probable duration thereof.

72. The variation of pressure at any consumer’s terminals
    shall not under any conditions exceed 4 per cent. above or
    below the normal pressure at which he is being supplied.

73. The licensee shall not use the said electric lines, or
    permit the same to be used, for any purpose until the Minister
    has given him notice in writing that he has received from
    the Inspecting Engineer a certificate that the works hereby
    authorized have been satisfactorily carried out.

74. The Minister may at any time order an inspection to
    be made of the lines and wires of the licensee. If any defect
    is found to exist it must be remedied forthwith; and if
    serious in the opinion of the Inspecting Engineer the Minis-
    ter may, on receipt of the report, direct the licensee to at
    once cease transmitting energy either over the whole of the
    lines and wires, or over any part thereof, as to him may seem
    fit, until such defect is repaired or remedied. The cost of
    such inspections shall be borne by the licensee.

75. After the supply of energy has begun, not less than
    fourteen days’ notice in writing shall be given to the Resi-
