Description

This authoritative, best-selling guide has been extensively updated with the new technical requirements of the IET Wiring Regulations (BS 7671: 2008) Amendment No. 1:2011, also known as the IET Wiring Regulations 17th Edition. With clear description, it provides a practical interpretation of the amended regulations – effective January 2012 – offers real solutions to the problems that can occur in practice.

This revised edition features:

  • new material on hot topics such as electromagnetic compatibility (EMC), harmonics, surge protective devices, and new special locations including medical locations, and operative or maintenance gangways;
  • highlights the changes that have been made in this latest Amendment and their impact in practice;
  • examples of how to comply with the Wiring Regulations;
  • fully-integrated colour including sixty brand new colour illustrations, twenty tables and new high-quality photographs.

This essential guide retains its handy format, ideal for practicing electricians, trainee electricians and apprentices to carry with them for quick reference. It is a valuable resource for all users of BS 7671 who want to understand the background to the Regulations; electrical engineers and technicians, installation and design engineers, consulting and building services engineers, also dedicated inspectors and testers.
