Section 51, The Machinery (Safe Working Citation

(I) ~n every overhead line all conductor.s shall be :::.headefficiently msulated and secured, and every precautiOn shall be taken to prevent such conductors from falling away from their supports. (2) Adequate means shall be provided to render any such live conductor dead in the event of its falling, due to breakage or otherwise. (3) In the design of such overhead lines the minimum factors of safety shall apply to each support and shall refer to the breaking load of the structure. Such minimum factors of safety shall be subject to the approval, in writing, of the Chief Inspector of Machinery. (4) Such overhead lines may be erected along or across thoroughfares, roads, railways, tramways or buildings subject to the prior approval, in writing, of an Inspector who may impose thereon such conditions as he may consider necessary.

(6) The minimum vertical height of electrical conductors and other wires from the ground, except in the case of electric trolley wires and service lines for lighting domestic use and telephone lines, shall be sixteen feet. (7) No overhead lines shall be erected nearer than 300 feet to any explosive magazine, except with the previous approval, in writing, of the· Chief Inspector of Machinery. (8) All supports shall be of substantial construction and shall be placed at intervals of not more than 200 feet apart when the direction of the line is straight, and of not more than 150 feet apart when the line is not straight, provided that such intervals may be varied with the approval, in writing, of the Chief Inspector of Machinery. 1858 Cap. 218] Machinery (Safe Working &; Inspection) Underground cables. Insulation or earthing of certain parts of electrical apparatus. (9) Service lines shall be connected to line conductors at a point of support only and shall be efficiently insulated. {10} All systems of overhead lines shall be suitably protected against the effects of atmospheric electricity. (11} No telephone lines shall be placed on the same support as other overhead lines except for the purpose of direct communication between power houses and sub-stations and then only with the prior approval of the Chief Inspector of Machinery. (12) Every overhead line, including its supports and all structural parts and all electrical appliances and devices belonging to or connected with the line, shall be regularly inspected and efficiently supervised and maintained as regards electrical and mechanical conditions.
