through; but when permitted to be taken through, the
crossing shall be made at a pole in a manner to be approved
by the Minister of Telegraphs.

Where the electric lines intersect telegraph lines, the latter
shall be suitably insulated if deemed necessary; and when
the crossing is above and near a pole, the spans on each side
of the pole may be insulated. This insulation shall be effected
at the expense of the licensee in cases where the telegraph
lines existed previously to the erection of the electric lines.

Where high-pressure electric lines intersect telegraph lines
the former shall be insulated with not less than 300-megohms
grade of vulcanized rubber, and the low-pressure wires with
weather-proofed insulation as prescribed in section 29.

Where deemed necessary efficient guard-wires shall be
erected in a manner to meet with the approval of the Minister
of Telegraphs at all crossings or places where electric lines
intersect telegraph lines, or at any place where such protection
may be considered necessary.

The licensee shall bear the expense of such guard-wires in
all cases where an electric line intersects any telegraph line
previously existing.

Where electric lines are on one side of the road and electric
telegraph lines on the other, and service is required to be given
from either to the other side of the road, the licensee and the
Minister of Telegraphs shall give to each other reasonable
facilities as far as possible to effect supply.

In running the lines authorized by this license through or
along any road where no telegraph line exists the licensee
shall keep to one side of the road, and in running wires to the
opposite side of the road the licensee shall arrange so as to
interfere as little as possible with the route of any future
telegraph lines.

32. Where electric lines are permitted to be supported on
    telegraph poles all details of the supports and of the insulation
    of the adjacent spans shall be approved by the Minister of
    Telegraphs, who may, on giving to the licensee reasonable
    notice in that behalf, require the licensee to remove such
    electric lines at any time from such telegraph poles, and
    without payment of any compensation to the licensee.

Where overhead electric lines at extra high pressure cross
telegraph lines, the electric lines shall be subject to such
special conditions as may be required by the Minister of Tele-
graphs in each case of such crossing.

The cost of all necessary guard-wires and special provisions
required to comply with this clause shall be borne by the
licensee.

33. Service lines shall be taken direct from line-insulators
    to insulators supported and firmly attached to some portion
    of the consumer’s premises which is not accessible to any
    person without the use of a ladder or other special appliance.
    Every portion of any service line other than a neutral wire
    which is outside a building and accessible therefrom shall be
    rubber insulated.

34. Every aerial line, including its supports, its con-
    ductors, and their insulating covering, and all structural
    parts and electric appliances and devices belonging to or
    connected with the line, shall be duly and efficiently main-
    tained as regards both electrical and mechanical conditions.

35. Where high-pressure transformers are attached to
    poles they shall be placed so as to be inaccessible except by
    the use of a ladder or other special appliance. Where high-
    pressure transformers are placed in sub-stations, all high-
    tension conductors shall be thoroughly insulated or protected
    from accidental contact; and the sub-station shall be entirely
    inaccessible to unauthorized persons. Where high-tension
    transformers are placed on consumers’ premises, the whole
    of the apparatus shall be enclosed or rendered inaccessible
    except to authorized persons. The cases of all transformers
    shall be earthed by means of a copper conductor at least
    0·022 square inch in section.

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

37. Underground conductors shall be thoroughly insulated,
    and shall be protected from mechanical damage by steel
    armouring or by wooden boxing or earthenware, stoneware,
    concrete, iron, or fibre conduits or pipes. They shall be
    laid wherever possible under the footpaths and with a cover
    of at least 12 in. from the surface of the pavement. Where
    laid under any other part of the road such cover shall be
    increased to 2 ft.

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

Where any underground line crosses or is in proximity
to any metallic substance, special precaution 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.

38. All underground metallic 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.

The covers of street cable-boxes shall be so secured that
they cannot be opened except by means of a special appliance.
Street boxes shall be either filled solid with cable compound
or oil, or if not so filled shall be inspected from time to time
for the presence of gas, and suitable action shall be taken
to check its influx and accumulation.

39. Every main, either overhead or underground, shall be
    tested for insulation after having been placed in position
    and before it is used for the purposes of supply, the testing
    pressures being at least 500 volts, and the licensee shall
    duly record the results of the tests of each main or section
    of a main, and forthwith forward a report thereon to the
    Resident Engineer of the Public Works Department at
    Whangarei.

The insulation of every complete circuit used for the supply
of energy, including all machinery, apparatus, and devices
forming part of or in connection with such circuit, shall be
so maintained that the leakage current shall not under any
conditions exceed one-thousandth part of the maximum
supply current. Every leakage shall be remedied without
delay. Every such circuit shall be tested for insulation at
least once in every month, and the licensee shall duly record
the results of the tests.

40. The licensee 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 premises, being
    maintained in a safe condition and in all respects fit for
    supplying energy.

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.

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 con-
tained within a suitable locked or sealed receptacle or fireproof
construction.

All electric wires and apparatus on a consumer’s premises,
except such parts as require to be earthed, shall be highly
insulated and suitable for the voltage at which the supply
is given. They 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.

41. The licensee 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 wiring and fittings
    are suitable for the voltage at which supply is given, that the
    installation is generally in accordance with the requirements
    of good practice, and that the connection or continuance
    of supply would not cause a leakage from those wires dangerous
    to life or property or deleterious to the rendering of good
    service.

For the purposes of satisfying itself that the requirements
of this license are being observed, in so far as they apply to
wires on a consumer’s premises, the licensee may require that
notice must be served upon it of the intention to instal wires,
fittings, lamps, motors, or other apparatus on any such
premises, and may inspect and test the same during any
reasonable hours while the installation of such is in progress.

42. If the licensee is reasonably satisfied, after making all
    proper examination on the completion of the installation,
    by testing or otherwise, that the wiring and fittings are not
    suitable for the voltage being employed, or 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 are not being complied with,
    then and in such case any officer of the licensee, duly autho-
    rized by it in writing, may, for the purpose 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 the license are com-
    plied with, by notice require the consumer, at some reason-
    able time after the service of a notice, to permit him to
    inspect and to test the wires and fittings belonging to the
    consumer forming part of the circuit.

If on such testing and inspection the officer discovers a
leakage from the consumer’s wires exceeding one-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
