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, unless 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.

THOS. MACKENZIE,
Acting Minister of Telegraphs.

Wellington Gas Company (Limited) authorized to erect an Electric Line in Miramar Avenue, Miramar.

IN exercise of the power and authority conferred upon me by the Post and Telegraph Act, 1908, I, Thomas Mackenzie, the Acting Minister of Telegraphs, appointed under the said Act, do hereby authorize and license the Wellington Gas Company (Limited) to erect, construct, lay down, and maintain an electric line for lighting and power purposes, being an undertaking not of a public nature, through the street within the Borough of Miramar known as Miramar Avenue, and shown on the plan marked “A” deposited in the office of the Secretary of the Post and Telegraph Department, and on which plan the electric line is indicated by a yellow line, and which is signed by me as such Minister as aforesaid, subject to the following conditions, viz. :

DEFINITIONS.

IN the following regulations “pressure” means the difference of electrical potential between any two conductors through which a supply of energy is given, or between any part of either conductor and the earth.

As the conditions of supply are such that the pressure does not exceed 250 volts, the supply shall be deemed a low-pressure supply.

Any metallic body to be “efficiently connected with the earth” shall be connected with the general mass of the earth in such manner as will insure at all times an immediate and safe discharge of electrical energy.

1. The supply of electrical energy shall be given by the continuous-current two-wire system, and shall be supplied at a pressure of 220 to 230 volts.

2. The conductors shall be of hard drawn copper, insulated throughout their entire length with not less than 300-megohms-per-mile grade of vulcanized rubber, and shall be laid underground in 1¼-inch galvanized-iron pipes with watertight joints. The minimum depth below the formation level of the road shall be 15 in.

3. The sectional area of the conductors employed shall be such as to occasion no rise of temperature in the conductor, or any part thereof, to such an extent as to materially alter the physical condition or specific resistance of the insulating covering, or in any case to raise such temperature to a greater extent than 30° Fahr. The cross-sectional area and the conductivity at joints must be sufficient to avoid local heating, and the joints must be carefully made, and must be protected against corrosion.

4. 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 prevent damage from heavy traffic, and reasonable means shall be taken to prevent the accumulation of gas in such receptacles.

5. 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.

6. 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.

7. The covers of street boxes shall be so secured that they cannot be opened except by means of a special appliance. 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.

8. The mains used for the supply of electrical energy shall be tested for insulation after having been placed in position and before they are used for the purpose of supply, the test pressure being at least 220 volts, and the result of the testing shall be duly recorded.

9. The insulation of the mains and all machinery, apparatus, and devices forming part of or in connection with the 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 result of these tests shall be duly recorded.

10. All material used for insulating electric lines or apparatus shall be of the best quality, and thoroughly durable and efficient, having regard to the conditions of its use. Suitable provision shall be made for the protection of the insulating material against injury or removal.

11. The service mains shall be so led into the building and so protected as not to be accessible to any person without the use of a ladder or other special appliance.

12. The line, including its supports, its conductors and their insulating covering, and all the structural 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.

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

14. A suitable safety-fuse or other automatic circuit-breaker shall be inserted in the service mains, as close as possible to the point of entry, and contained within a suitable locked or sealed receptacle of fireproof construction.

15. All electric lines at the receiving station 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. The installation generally shall be in accordance with the requirements of good practice, and maintained so that the wires and fittings at the receiving station shall not permit of a leakage exceeding one ten-thousandth part of the maximum supply current to the premises.

16. The Minister of Telegraphs may at any time order an inspection to be made of the works, lines, and wires of the company. 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 company to at once cease transmitting energy over the mains until such defect or defects are repaired or remedied. The cost of such inspection shall be borne by the company.

17. If the company 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. The recovery of a penalty under this license shall not affect the liability, if any, of the company 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.

The Corporation of the Borough of Akaroa authorized to erect Electric Lines within the Borough of Akaroa.

IN exercise of the power and authority conferred upon me by the Post and Telegraph Act, 1908, I, Thomas Mackenzie, the Acting Minister of Telegraphs, appointed under the said Act, do hereby authorize and license the Mayor, Councillors, and Burgesses of the Borough of Akaroa (hereinafter referred to as “the Corporation”) to erect, construct, lay down, and maintain electric lines for lighting and power purposes through those streets within the borough in which the electric lines are shown on the plan marked “A” deposited in the office of the Secretary of the Post and Telegraph Department, and on which plan the electric lines are indicated by red lines, and which is signed by me as such Minister as aforesaid, subject to the following conditions, viz. :

DEFINITIONS.

IN the following regulations “consumer’s wires” means any electric lines on a consumer’s premises which are connected to the service lines of the Corporation at the consumer’s terminals.

“Pressure” means the difference of electrical potential between any two conductors through which a supply of energy is given, or between any part of either conductor and the earth.
