Part 7 of the BSI 7671; 1992-Requirements for Electrical Installations (The IEE Wiring Regulations) covers inspection and testing and Chapter 71 contains the requirements for initial verification. Here, the author describes how initial verification requires that an installation be inspected and tested as the work proceeds, ie during erection and before being put into service, in order to verify that the design of the installation, the selection of materials and the equipment as well as the methods of installation, all conform to the relevant Regulations. Testing and inspection are also covered in detail.
