Example text

Wiring systems shall be installed so that the general building structural performance and fire safety are not reduced. 2 Cables complying with, at least, the requirements of IEC 60332-1 and products having the necessary fire resistance specified in IEC 60614 and in other IEC standards for wiring systems may be installed without special precautions. 3 NOTE In installations where particular risk is identified, cables complying with the more onerous tests for bunched cables described in IEC 60332-3-24 may be necessary.

4 Where an electrical service is located in close proximity to non-electrical services, both the following conditions shall be met: wiring systems shall be suitably protected against the hazards likely to arise from the presence of the other services in normal use; and protection against indirect contact shall be afforded in accordance with the requirements of clause 41 3 of IEC 60364-4-41, non-electrical metallic services being considered as extraneous conductive parts. 529 Selection and erection of wiring systems in relation to maintainability, including cleaning The knowledge and experience of the person or persons likely to carry out the maintenance shall be taken into account in the selection and erection of the wiring system.

7) Les parcours des canalisations qui sont rigidement fixées et encastrées dans les parois doivent être horizontaux ou verticaux ou parallèles aux arêtes des parois. Les canalisations noyées dans les plafonds, les parois ou les planchers et non fixées peuvent suivre le parcours pratique le plus court. 8) Les câbles souples doivent être installés de manière à éviter des efforts excessifs de traction sur les conducteurs et les connexions. 1 Lorsque les conditions connues ou prévues présentent un risque (AK2), les canalisations doivent être choisies en conséquence ou des mesures spéciales de protection doivent être prises.
