ELECTRICITY SUPPLY.

No. 18 of 1911.

1939

(4) Where the supply is for any special purpose other than those above mentioned, or where the pressure of the supply exceeds the limits of medium pressure, it shall be subject to such other regulations as the Governor in Council may prescribe.

three-wire

3. When the pressure between the outer conductors of a three-wire system exceeds 250 volts and the three wires of the system or two pairs of wires are brought into a consumer's premises, the supply shall be given to two pairs of terminals arranged in such a manner that there shall be no danger of any shock, and the wiring from those terminals shall be kept distinct.

system into consumer's premises.

4. The sectional area of the conductor in any electric line other than low tension laid or erected in any street after the date of these regulations shall not be less than that of a strand of seven wires, each of which is of No. 22 standard wire gauge, and the sectional area of every wire in a strand forming any such conductor shall not be less than that gauge, and where such stranded conductor is erected it shall be suspended from a suitable bearer wire or shall be protected by a suitable cradle fixed underneath. In the case of low tension conductors in any electric line the sectional area shall not be less than that of a single wire of No. 16 standard wire gauge efficiently insulated.

This regulation shall not apply in the case of an electric line placed in a lamp post.

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 pressure to 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.

medium pressure mains.

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.

of high pressure circuit.

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 connexion with earth exists.
