SEPT. 17.] THE NEW ZEALAND GAZETTE. 3557
Where the transmission-line runs parallel and adjacent to
the telegraph line, suitable and approved transpositions of
the electric power lines shall be effected if so required by the
Minister of Telegraphs, the expense of such transpositions to
be borne by the Council.
The cost of all necessary guard-wires or other devices and
special provisions required to comply with this clause shall be
borne by the Council, when the telegraph lines are erected
before the electric lines. In other cases the Council,
on receipt of notice from the local officer of the Telegraph
Department that it is proposed to run a telegraph line
along the route, shall forthwith make the necessary changes
required to comply with this clause at any point at which
electric lines already cross such routes.
Earth-wires.
27. Earth-wires, where led down poles, shall be protected
by a casing for a distance of 8 ft. from the ground. A test
shall be made every three months, and oftener if required,
of all earths, to ensure that the earth-wire is intact and that
the earth is effective.
Railway Crossings.
28. No work of any nature shall be erected or constructed
in pursuance of this license upon, over, or under any part of
the Government railways until the Council has obtained the
consent of the Minister of Railways thereto, as required by
section 4 of the Government Railways Amendment Act, 1910
(No. 2).
Service Connections.
29. Service connections from aerial lines shall be taken
direct from insulators, and shall not be tapped off between
insulators. They shall be led as directly as possible to insu-
lators 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 aerial line which is outside a building,
and is within 7 ft. from any part of the building, shall be
rubber-insulated.
Where an aerial line crosses or is in proximity to any
metallic substance precautions shall be taken by the Council
against the possibility of the line coming into contact with
the metallic substance by breakage or otherwise.
Facilities for Service Connections.
30. Where electric lines are on one side of the street
and telegraph lines on the other, and service is required
to be given from either to the other side of the street, the
Council and the Minister of Telegraphs shall give to each other
reasonable facilities as far as possible to effect supply.
Arc Lamps.
31. 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.
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.
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.
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.
They may be run in series, and at any available voltage up
to 400 volts. 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 provided with a switch on each circuit.
Maintenance.
32. Every aerial line, including its supports, its conductors,
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 maintained by the
Council as regards both electrical and mechanical conditions.
High-pressure Transformers.
33. 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 con-
ductors shall be thoroughly insulated or protected from
accidental contact, and the sub-station shall be entirely
inaccessible to unauthorized persons. Where high-pressure
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.
Where cables are led to and from transformer enclosures
they shall be protected on the poles by being run in iron
pipes, which shall be effectively earthed.
Lightning-arresters.
34. 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.
Underground Conductors.
35. 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 this cover shall be increased
to 2 ft.
All conduits, pipes, casings, and street boxes used as
receptacles 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.
Earthing Conduits.
36. All 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.
Street Boxes.
37. 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.
Insulation of Electric Mains.
38. 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
pressure being at least 500 volts, and the Council shall duly
record the results of the tests of each main or section of a
main and forthwith forward a report thereon to the Public
Works Engineer at present stationed at Stratford.
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 by the
Council without delay. Every such circuit shall be tested for
insulation at least once in every month, and the Council shall
duly record the results of the tests and forward a report
thereof at the end of each month to the Public Works
Engineer at present stationed at Stratford.
Continuity of Supply.
39. From and after the time when the Council commences
to supply energy in pursuance of this license it shall maintain
continuously sufficient power for the use of all the consumers
for the time being entitled to be supplied; provided also that,
for any purposes connected with the efficient working of the
undertaking, the Minister may give permission to the Council
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.
Supply to Consumers.
40. The owner or occupier of any premises within the area
of supply included in the license shall be entitled to a supply
of electrical energy on the following conditions :-
(a.) If within 60 ft. of an electric line belonging to the
Council service shall be made free of cost.
(b.) If more than 60 ft. distant to any electric line belong-
ing to the Council, the Council shall run the necessary lines
