2. The trolley-wires shall not be less than No. 2/0 S.W.G. hard-drawn solid copper or cadmium-copper wires, firmly attached to approved insulators, and erected on supports placed not more than 130 ft. apart.

Trolley-wire feeder-cables, if carried overhead, shall be covered with weatherproof triple braiding: Provided that, where circumstances permit, the Minister may approve of bare conductors being used; and provided that where electric feeder-cables intersect the Post and Telegraph Department’s lead-covered cables, vulcanized indiarubber insulation of not less than 600 megohm grade shall be substituted for weatherproof triple braiding.

Double insulation shall be provided between the positive and negative trolley-wires and between the positive trolley-wire and earth. Single insulation shall be provided between the negative trolley-wire and earth on all span wires and pull-offs.

The maximum difference of potential between the positive and negative trolley-wires, and between trolley-wire feeders and the ground shall not exceed 650 volts.

The best means available shall be adopted for preventing the occurrence of undue sparking at the rubber or rolling contacts in any place.

3. The conductors shall be carried on substantial and durable supports, which shall be designed to have a factor of safety of four in the case of steel, iron, or ferro-concrete, and five in the case of wood, calculated upon the ultimate strength of the material, assuming the wind-pressure to be 30 lb. per square foot upon a plane surface and 18 lb. per square foot upon a diametral plane upon a cylindrical surface.

4. The trolley-wire shall not in any part thereof be at a less height than 18 ft. from the surface of the ground.

5. (1) Where telegraph, telephone, or electric-fire-alarm wires (hereinafter referred to as “the first-mentioned wires”), are carried along either overhead or underground on one side of the road to be used by the trackless electric car, the said electric lines (either overhead or underground) of the trackless electric-car system shall be carried along on the other side thereof unless otherwise approved by the Minister of Telegraphs.

(2) At all points where it is necessary for the said electric lines to be carried across the first-mentioned wires, they shall be carried across and under the same at right angles if possible, and the first-mentioned wires shall be carefully insulated at the expense of the licensee over a sufficient length to prevent any contact in the event of accident to either line, and proper guard-wires effectively earthed shall be provided where necessary, at the like expense, to prevent the first-mentioned wires, or any other overhead wires, from getting into contact with the said electric lines. Where the first-mentioned wires run parallel to and higher than the said electric lines, and the poles supporting the pull-off or span wires are on the same side of the road as those supporting the first-mentioned wires, and wherever it is considered that by reason of accident or otherwise there is a danger of the first-mentioned wires falling across the said electric lines or their supports, guard-hooks and approved insulators, or other approved protective devices, shall be provided and erected by and at the expense of the licensee to the satisfaction of the Minister.

(3) Where poles are erected on both sides of the road those on the one side of the road must comply with the requirements of the Minister of Telegraphs in order to provide reasonable facilities for their joint use.

6. The design of all poles, posts, standards, brackets, and other attachments used in connection with the said electric lines shall be subject to the approval of the Minister, and they shall be constructed in accordance with such approved design, and erected in such manner, as is approved in writing by the Minister.

7. The licensee shall take all reasonable precautions in constructing, placing, and maintaining the said electric lines and other works of all descriptions, and also in working the undertaking so as not to injuriously affect by fusion or electrolytic action any gas or water pipes, sewers, drains, or conduits, or other pipes, structures, or substances, or to injuriously interfere with the working of any telegraph, telephone, electric-lighting, or electric-fire-alarm lines or apparatus.

8. This license shall, unless sooner determined in accordance with the provisions hereinafter expressed, continue in force for a period of ten years from the date hereof. Upon expiry of the said term, or upon sooner determination of this license by revocation or otherwise, all rights hereby granted to the licensee shall cease and determine; but such expiration or determination shall not relieve the licensee of any liability theretofore incurred under this license.
