Handbook on the Wiring Regulations: The IEE Wiring Regulations BS 7671, 3rd Edition

This well established handbook, written and sponsored by the Electrical Contractors' Association and Select (formerly the Electrical Contractors' Association of Scotland), provides a detailed, authoritative guide to the Wiring Regulations, BS 7671: Requirements for Electrical Installations.

As the regulations are not drafted by topic, the handbook will be particularly useful in guiding designers, installers, inspectors and testers round the various requirements. It gives practical guidance on how to approach new installations, extensions to existing installations, and the more extensive testing and inspection which are required.

The handbook has been revised to take account of amendments introduced by BS 7671:2001 effective from 1 January 2002. The most significant changes are:

· chapter 13 rewritten to include three sections on protection for safety, design and selection of electrical equipment

· a new chapter 44 on overvoltage protection

· a new chapter 48 on high fire risk situations

· revisions to the requirements on rooms containing a bath or shower

· new earthing requirements for the installation of equipment with high protective conductor outlets
