The Electricity Supply Regulations 1988

Position, insulation and protection of electric lines

14.—(1) For the purposes of this regulation an electric line placed above ground which is connected to any source of voltage shall be considered to be ordinarily accessible if and so long as it may be reached by hand from any scaffolding, ladder or other construction erected or placed on, in, against or near to a building or structure, but shall not be considered to be so accessible during such reasonable period during and after the erection or placing as may be necessary to arrange for the protection of that line if that was the purpose, or part of the purpose, of the erection or placing.

(2) Any part of an electric line placed above ground which is not connected with earth and which is not ordinarily accessible shall be insulated.

(3) Any part of an electric line placed above ground which is not connected with earth and which is ordinarily accessible shall be—

(a)made dead; or

(b)so insulated that it is protected, so far as is reasonably practicable, against mechanical damage or interference; or

(c)adequately protected to prevent danger.

(4) Any bare low voltage electric line placed above ground which is not connected with earth shall be situated, throughout its length, vertically above a bare electric line which is connected with earth.

(5) Nothing in this regulation shall require the supplier to insulate or protect any part of any electric line placed above ground which, but for the provisions of paragraph (1), would not be required to be insulated or protected unless—

(a)he has been given reasonable notice of the erection of the building or structure which would cause that line to become accessible; and

(b)unless otherwise agreed, the person responsible for the erection of that building or Structure which would cause that line to become accessible Shall have paid, or undertaken to pay, the reasonable cost of the insulation of the line.

(6) Nothing in this regulation shall be taken to allow the application of temporary insulation to any electric line other than a low voltage line.
