Cable for use in an electrical installation should be selected to comply with the electrical characteristics of current rating, voltage drop, etc., as required by Parts 4 and 5 of BS 7671 and the physical characteristics required by Chapter 52 Selection and Erection of Wiring Systems.
The correct selection and erection of a complete wiring system is necessary to provide compliance with Chapter 52.
Overspecification of cable performance requirements can result in increased installation costs and it is incumbent on the designer to assess all aspects of the overall performance required by the user.
This unit will discuss these concepts.
