Electrical Supply Regulations




Aug. 3.] THE NEW ZEALAND GAZETTE. 2443

any part of any building or erection other than a support
for the line, except where brought into a building for the
purpose of supply. Where the wires cross the railway-
line the minimum height of all shall be 18 ft., unless the
Railway Department requires a greater height, and the
permission of that Department shall be obtained by the
Corporation for every such crossing.

  1. Service lines from aerial lines shall be led as directly
    as possible to insulators firmly attached to some portion
    of the consumer’s premises which is not accessible to any
    person without the use of a ladder or any other special
    appliance. Every portion of any service line which is out-
    side a building, and is within 7 ft. from any part of the
    building, shall be rubber-insulated.

  2. Where an aerial line crosses a street, the angle
    between the line and the direction of the street at the
    place of crossing shall not be less than 60 degrees, and the
    spans shall be as short as possible.

  3. Where an aerial line crosses or is in proximity to any
    metallic substance, precautions shall be taken against the
    possibility of the line coming into contact with the metal-
    lic substance, or of the metallic substance coming into
    contact with the line by breakage or otherwise.

  4. Efficient guard-wires shall be erected in a manner
    to meet with the approval of the Minister of Telegraphs
    at all crossings and places where the electric-light wires
    intersect telegraph or other wires, as may be required by
    the Minister to be so protected. The Corporation shall
    bear the expense of such guard-wires in all cases where
    an electric-light wire intersects a telegraph or other wire
    previously existing.

  5. Every aerial line, including its supports, its con-
    ductors, and their insulating covering, and all the struc-
    tural parts and electrical appliances and devices belonging
    to or connected with the line, shall be duly and efficiently
    supervised and maintained as regards both electrical and
    mechanical conditions.

  6. An aerial line shall not be permitted to remain
    erected after it has ceased to be used for the supply of
    energy, unless the Corporation intends within a reasonable
    time again to take it into use.

  7. The electric-light wires may be placed wholly under-
    ground or partly underground and partly overhead.

  8. All conduits, pipes, casings, and street boxes used
    as receptacles for electric lines shall be constructed of
    durable material, and shall be of ample strength to pre-
    vent damage from heavy traffic, and reasonable means
    shall be taken to prevent the accumulation of gas in such
    receptacles.

  9. Where any underground line crosses or is in proximity
    to any metallic substance, special precautions shall be taken
    against the possibility of any electrical charging of the
    metallic substance from the line, or from any metallic
    conduit pipe or casing enclosing the line.

  10. All underground metal conduits, pipes, or casings
    containing an electric line shall be efficiently earthed, and
    shall be so jointed and connected across all street boxes
    and other openings as to make good electrical contact
    throughout their whole length.

  11. The covers of street boxes shall be so secured that
    they cannot be opened except by means of a special ap-
    pliance. Street boxes shall be inspected from time to time
    for the presence of gas, and suitable action shall be taken
    to check its influx and accumulation.

  12. The Corporation shall be responsible for all electric
    lines or wires, fittings, and apparatus belonging to it, or
    under its control, which may be upon a consumer’s pre-
    mises, being maintained in a safe condition and in all
    respects fit for supplying energy.

  13. 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.

  14. Where any portion of any electric line or any support
    for an electric line is exposed in such a position as to be
    liable to cause injury from lightning, it shall be efficiently
    protected against such liability.

  15. A suitable safety-fuse or other automatic circuit-
    breaker shall be inserted in each service line within a
    consumer’s premises as close as possible to the point of
    entry, and contained within a suitable locked or sealed
    receptacle of fireproof construction.

  16. All electric wires placed on a consumer’s premises
    shall be highly insulated, and shall be thoroughly protected
    against injury to the insulation or access of moisture. All
    electric wires shall be so fixed and protected as to prevent
    the possibility of electrical discharge to any adjacent
    metallic substance.

  17. 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
    requirements of this license are complied with, that the
    wirings 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.

For the purpose of satisfying itself that the requirements
of this license are being observed, the Corporation may
require that notice be served upon it of the intention to
install wires, fittings, lamps, motors, or other apparatus on
any premises, and may inspect the same during any reason-
able hours while the installation of such is in progress.

  1. 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 that any other require-
    ments of this license are not being complied with, then
    and in such case any officer of the Corporation, duly autho-
    rized by it in writing, or, if the Corporation so requires,
    on application by it to the Minister of Telegraphs, any
    officer of the Post and Telegraph Department (hereinafter
    referred to as “an Electric Inspector”) instructed to so
    act, may, for the purpose of discovering whether the leak-
    age exists at any part of a circuit within or upon any con-
    sumer’s premises, or whether the wiring is suitable and
    the general requirements of the 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 to 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 services.

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
supply current to the premises, or that the requirements
of this license 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 dis-
continuing the supply, and in either case supply shall not
be given until it is reasonably satisfied that the installa-
tion is in conformity with the requirements of this license.

  1. If any consumer is dissatisfied with the action of the
    Corporation 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 applica-
    tion to the Minister of Telegraphs, and on payment of the
    cost, be inspected and be tested for the existence of leakage
    by an Electric Inspector.

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

  1. From and after the time when the Corporation com-
    mences to supply energy it shall maintain continuously
    sufficient power for the use of all the consumers for the
    time being entitled to be supplied: Provided that, for
    any purposes connected with the efficient working of the
    undertaking, the Minister of Telegraphs may give per-
    mission to the Corporation to discontinue the supply at
    such intervals of time and for such periods as he may
    think expedient. When the supply is so discontinued,
    public notice shall be given, when practicable, of such
    discontinuance, and of the probable duration thereof.

  2. The Minister of Telegraphs may at any time order
    an inspection to be made of the works, lines, and wires of
    the Corporation used for electric lighting and power pur-
    poses. When a defect or defects are found to exist they
    must be remedied forthwith, and should they be serious
    in the opinion of the officer or person inspecting, the
    Minister of Telegraphs may, on receipt of the report,
    direct the Corporation to at once cease transmitting energy
    either over the whole of the Corporation lines and wires,
    or over any part thereof, as to him may seem fit, until
    such defect or defects are repaired or remedied. The cost
    of such inspection shall be borne by the Corporation.

  3. After the supply of energy has begun, particulars
    shall be given to the local Postmaster of each further pro-
    posed extension or alteration of lines or wires.

  4. If the Corporation makes default in complying with
    any of the provisions of this license it shall be liable to
    a penalty not exceeding £20 for every such default; but
    it shall not be held to have committed default for any
    failure to maintain power continuously if such failure be
    due to the breakdown of machinery or other accident, un-
    less such breakdown or accident shall be proved to be due
    to negligence on the part of the Corporation.

The recovery of a penalty under this license shall not
affect the liability, if any, of the Corporation to make
compensation in respect of any damage or injury which
may be caused by reason of the default.

As witness my hand, this twenty-fourth day of July,
one thousand nine hundred and eleven.

THOS. MACKENZIE,
Acting Minister of Telegraphs.
