239 Low voltage conductors supported along the façade of a building or structure

(1) A low voltage conductor (other than a low voltage insulated conductor) must not, at any time, be supported along—

(a) the façade of a building or structure; or

(b) any part of a building or structure that adjoins a public way or space.

(2) A low voltage insulated conductor supported along the façade of a building or structure or any part of a building or structure adjoining a public way or space, must not, at any time, be closer to a part of a building or structure or the ground set out in Column 1 of Table 239 than the relevant minimum distance specified in Column 2 of that Table that corresponds to that part of the building or structure or the ground.

(3) For the purposes of this regulation, a low voltage conductor is supported along a building or structure if the conductor is supported by the building or structure at a distance of no more than 300 millimetres from the building or structure.

The illustrations below show the locations where façade mounted low voltage insulated conductors are permitted. The following is an explanation of the letters in the illustrations:

A is the minimum distance of 2500 mm to a low voltage insulated conductor vertically from the ground of a building or structure.

B is the minimum distance of 300 mm to a low voltage insulated conductor above a window or door of a building or structure.

C is the minimum distance of 500 mm to a low voltage insulated conductor from each side of and below a window of a building or structure.

D is the minimum distance of 1000 mm to a low voltage insulator conductor from each side of a door or balcony of a building or structure.
