5. Every low pressure and medium pressure main, after having been placed in position, and before it is used for the purposes of supply, shall withstand a pressure equal to the maximum which it is intended to be subjected in use, and in any case at least 200 volts, and further, before being used as aforesaid, it shall be tested for insulation, and the company shall duly record the results of the tests of each main or section of a main.
6. A high pressure circuit shall not be brought into use unless the insulation of every part thereof has withstood the continuous application, during one hour, in the case of every electric line, of a pressure equal to the full working pressure to which it is intended to be subjected in use, and, in the case of every machine, device, or apparatus, of a pressure equal to the full working pressure to which it is intended to be subjected.
The company shall duly record the results of each test.
7. There shall be maintained by the company at each station or sub-station as may be necessary a leakage indicator of approved pattern and so arranged that the leakage on each main feeder can be readily ascertained at any time and a weekly test recorded. If at any time the leakage is in the opinion of the Director of Public Works excessive, he shall require the company to remedy the same and it shall forthwith be remedied.
Provided that where any part of any electric circuit is connected with earth, either in accordance with these regulations or with the approval of the Director of Public Works, the provisions of this regulation shall not apply to that part of that circuit so long as the connection with earth exists.
8. Every high pressure main, conductor, or other apparatus shall be protected by a suitable fuse or automatic circuit-breaker.
Provided that it shall not be incumbent upon the company to provide such a fuse or circuit-breaker for the outer conductor of a concentric main which is, in accordance with these regulations or with the approval of the Director of Public Works, efficiently connected with earth.
9. In every case where a high pressure supply is transformed for the purpose of supply to one or more consumers, some suitable automatic and quick-acting means shall be provided to protect the consumer's wires from any accidental contact with or leakage from the high pressure circuit, either within or without the transforming apparatus.
10. The metallic portion of every high pressure transformer, with the exception of the conductors thereof, shall be efficiently connected with earth except in respect of transformers supported on poles at such a height as to be inaccessible except by the use of a ladder or other special appliance: Provided that in such cases such poles shall be efficiently connected with earth.
11. Where any portion of any electric line or any support for any electric line is exposed in such a position as to be liable to cause from lightning.
