6. Installation

6.1 During the course of the installation of the conduit system, procedures for working and dressing the installation as recommended shall be employed.

6.2 All bends and sets shall be in accordance with regulation and specifications formed with

the aid of a helical spring fitted internally, with if necessary, the conduit warmed sufficiently for it to move without avoidable wall thinning of the out side of the bend.

6.3 Joints between PVC conduit + fittings shall be made with suitable adhesive, but

expansion couplings shall be installed where any length of conduit , inclusive of draw in boxes etc, exceeds five meters in length.

6.4 Conduits in floors shall be routed and installed so as to avoid the fixings of floor

standing equipment to be installed on the floor.

6.5 The conduits shall be adequately fixed to prevent excessive movement and damage during the pouring and setting of concrete and shall be protected from mechanical damage. Check there is no damage before screed / concrete is poured. Unless otherwise indicated to cast in conduits shall not be less than 30mm.cores to plastered over conduits shall not be less than 5mm.

6.6 Where conduits are left "open ended" prior to wiring they shall be protected by caps or

plugs to prevent the ingress of building material.

6.7 All conduits runs must be designed to permit wiring to be readily installed after the complete erection of the conduits through the available draw-in, accessory and luminary suspension boxes.

6.8 Where surface mounted equipment (other than luminaries) is specified, all concealed

conduits shall be terminated and an adaptable box installed recessed into the wall at every surface mounted equipment position.

6.9 Where conduits pass through an external wall/roof the conduit box shall be fitted on the

side and after wiring filled with an inert, permanently plastic compound having a high insulation value.

6.11 Make provision in conduit and trunking, installation where building expansion joints are

crossed or settlement is likely.

6.12 Ensure conduits are not concealed until works has been inspected and approved. Ensure that conduit and fittings buried in concrete or behind plaster are protected against corrosion or electrolytic action prior to rendering.
