that it cannot with proper care be left in partial contact.
This applies to each pole of double-pole or multipole
switches or circuit-breakers. Every switch intended to be
used for breaking a circuit, and every circuit-breaker, shall
be so constructed that an arc cannot accidentally be maintained.

65. Every fuse and every automatic circuit-breaker used
    instead thereof shall be so constructed and arranged as
    effectively to interrupt the current before it so exceeds the
    working-rate as to involve danger. It shall be of such
    construction or be so guarded or placed as to prevent
    danger from overheating, or from arcing, or the scattering-
    ing of hot metal or other substance when it comes into
    operation. Every fuse shall be either of such construction
    or so protected by a switch that the fusible metal
    may be readily renewed without danger.

66. Every electrical joint and connection shall be of
    proper construction as regards conductivity, insulation,
    mechanical strength, and protection.

67. Efficient means suitably located shall be provided
    for cutting off all pressure and for protecting from excess
    of current every part of a system, as may be necessary to
    prevent danger.

68. Every motor converter and transformer shall be
    protected by efficient means suitably placed, and so connected
    that all pressure may thereby be cut off from the
    motor converter or transformer, as the case may be, and
    from all apparatus in connection therewith.

69. Every motor shall be controlled by an efficient switch
    for starting and stopping, so placed as to be easily worked
    by the person in charge of the motor. In every place in
    which machines are being driven by any electric motor
    there shall be means at hand for either switching off the
    motor or stopping the machines if necessary to prevent
    danger.

70. If in any place portable apparatus should be used
    at a pressure exceeding low pressure, the portable apparatus
    and its flexible wire shall be controlled by efficient
    means suitably located and capable of cutting off the
    pressure, and the metal-work of the portable apparatus
    shall be efficiently earthed independently of any flexible
    metallic cover of the conductors, and any such flexible
    covering shall itself be independently earthed. The earthing
    as prescribed shall not be imperative in respect of
    testing-instruments being used by Corporation employees.

71. The general arrangement of switchboards shall, so
    far as reasonably practicable, be such that all parts which
    have to be adjusted or handled are readily accessible,
    and the course of every conductor may, when necessary,
    be readily traced. There should be sufficient space near
    them to enable them to be operated without danger, and
    the floor should be firm and even. Three-phase and direct-
    current connections, if on the same switchboard, shall be
    kept well apart, and the conductors arranged so that they
    can be readily distinguished.

72. All apparatus appertaining to a switchboard and
    requiring handling shall be so placed or arranged as to be
    safely operated. Measuring-instruments and indicators
    connected therewith shall be so placed as to be suitably
    observed, adequate precautions being taken to prevent
    danger.

73. In every switchboard for high-pressure—
    (a.) Every high-pressure conductor shall be so placed
    or protected as adequately to prevent danger.
    (b.) The metal cases of all instruments working at high
    pressure shall be either earthed or completely
    enclosed with insulating-covers. Where the instruments
    are controlled by an insulating transformer the earthing
    of one side of the secondary of the transformer and its core
    shall be efficiently made.
    (c.) All metal handles of high-pressure switches, and,
    where necessary to prevent danger, all metal gear
    for working the switches, shall be earthed.
    (d.) Any switchboard carrying high pressure shall be so
    arranged that work may be carried out on it
    without danger. If necessary the switchboard
    shall be made dead. If the switchboard is so
    arranged that it can be divided into sections, only
    that section on which work is to be done need be
    made dead, provided there is no danger to the
    workmen from the live wires of the adjoining
    sections.

74. All parts of motors or other apparatus at high
    pressure and within reach from any position in which any
    person employed or other persons may require to be shall
    be, as far as may be reasonably practicable, so protected
    as to prevent danger.

75. Where necessary to prevent danger, adequate precautions
    shall be taken either by earthing or by other suitable
    means to prevent any metal other than the conductor
    from becoming electrically charged.

THE NEW ZEALAND GAZETTE. [No. 89

76. Adequate precautions shall be taken to prevent any
    conductor or apparatus from being accidentally or inadvertently
    electrically charged when persons are working
    thereon.

77. Where necessary adequately to prevent danger, insulating
    stands or screens shall be provided and kept
    permanently in position, and shall be maintained in sound
    condition.

78. Portable insulating stands, screens, boots, gloves, or
    other suitable means shall be provided and used when
    necessary adequately to prevent danger, and shall be periodically
    examined by an authorized person.

79. Adequate working-space and means of access free
    from danger shall be provided for all medium- and high-
    pressure apparatus that has to be worked or attended to
    by any person.

80. All those parts of premises in which apparatus is
    placed shall be adequately lighted to prevent danger.

81. Only competent persons shall be permitted to perform
    any work where technical knowledge or experience
    is required in order adequately to avoid danger.

82. Instructions as to the treatment of persons suffering
    from electric shock shall be affixed in all premises where
    electrical energy is used above low pressure.

83. A notice shall be fixed in a conspicuous place at every
    motor and switchboard above low pressure, forbidding
    unauthorized persons to touch the motors or apparatus.

84. The Dunedin Corporation shall be responsible for the
    whole of the overhead lines and wires, and for all transformers
    in connection therewith, throughout the area of
    supply being erected and maintained in conformity with
    the requirements of these regulations.

85. The Corporation shall be responsible for all electric
    lines, fittings, and apparatus belonging to them, or
    under their control, which may be upon a consumer's
    premises being maintained in a safe condition, and in all
    respects fit for supplying energy, and in delivering the
    energy to a consumer's terminals the Corporation shall
    exercise all due precautions so as to avoid risk of causing
    fire on the premises.

86. The Corporation shall not connect the wires and
    fittings on a consumer's premises with its mains, or, in
    the case of premises already connected, continue the supply
    from its mains, unless it is reasonably satisfied that the
    wiring and fittings are suitable for the voltage at which
    supply is being given, that the installation generally is
    in accordance with the requirements of good practice, 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.

87. If the Corporation 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 Corporation
    or for which it is held responsible, or that any other requirements
    of good practice are not complied with, then and in such
    case any officer of the Corporation duly authorized by it in
    writing, or, if the Corporation so requires, on application by
    it to the Board of Control, any officer of that body (hereinafter
    referred to as "an Electric Inspector") instructed to so act,
    may, for the purposes of discovering 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 good practice 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. In any case where
    the Corporation requires the services of an Electric Inspector
    under this section it shall pay the cost of such inspection.

If on such testing and inspection the officer or the Electric
Inspector discovers a leakage from the consumer's wires exceeding
one ten-thousandth part of the maximum current to the
premises, or that the requirements of good practice are not
properly conformed to, or if the consumer does not give all
due facilities for inspection and testing, the Corporation shall
either not commence the supply or shall forthwith discontinue
the supply of energy to the premises in question, giving immediate
notice to the consumer of its reasons for not commencing
or for discontinuing the supply, and in either case supply
shall not be given until it is reasonably satisfied that the installation
is in conformity with the requirements of good practice.

88. If any consumer is dissatisfied with the action of the
    Corporation in refusing to give, or in discontinuing, or in
    not recommencing, the supply of energy to his premises, the
    wires and fittings of that consumer may, on his ap-
