This is the best-selling definitive guide to the wiring regulations -- BS7671. Now updated and in its sixth edition, the book takes into account all the latest regulations, providing working tables and examples for practising engineers and electricians. First published over 16 years ago, this book has been used by many colleges and teachers of BTEC, City and Guilds and NVQ electrical courses.
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
For more than 30 years, students and practising electricians have relied on John Whitfield to guide them through the complexities of the Wiring Regulations. Unlike other publications, it does not assume that readers are fully conversant with electrical theory. It assumes just a basic knowledge and introduces technical matter with brief easy-to-understand explanations. His Guide is a recognised brand, has consistently been a bestseller and regarded as THE guide to the Wiring Regulations. This 4th Edition covers Amendment 3:2015, regarded as ‘potentially life-saving’, which comes into effect July 2015. As in earlier editions, all useful relevant details derived from other IET publications such as Guidance Notes, Wiring Matters, which might otherwise be overlooked by electricians, are included. Importantly the Guide also benefits from the most up-to-date, hands-on expertise provided by the co-author, Andrew Hay-Ellis, whose credentials are second-to-none. He is an established author of vocational electrical books and, amongst other functions, is a Chief Examiner at City & Guilds.
The book provides step-by-step guidance on the design of electrical installations, from domestic installation final circuit design to fault level calculations for LV systems. Updated to include the new requirements in Amendment 3 to BS 7671:2008, the Electrical Installation Design Guide reflects important changes to: Definitions throughout the Regulations Earth fault loop impedances for all protective devices Amendment 3 published on 5 January 2015 and comes into effect on 1 July 2015. All new installations from this point must comply with Amendment 3 to BS 7671:2008.
Handbook of Electrical Installation Practice covers all key aspects of industrial, commercial and domestic installations and draws on the expertise of a wide range of industrial experts. Chapters are devoted to topics such as wiring cables, mains and submains cables and distribution in buildings, as well as power supplies, transformers, switchgear, and electricity on construction sites. Standards and codes of practice, as well as safety, are also included. Since the Third Edition was published, there have been many developments in technology and standards. The revolution in electronic microtechnology has made it possible to introduce more complex technologies in protective equipment and control systems, and these have been addressed in the new edition. Developments in lighting design continue, and extra-low voltage luminaries for display and feature illumination are now dealt with, as is the important subject of security lighting. All chapters have been amended to take account of revisions to British and other standards, following the trend to harmonised European and international standards, and they also take account of the latest edition of the Wiring Regulations. This new edition will provide an invaluable reference for consulting engineers, electrical contractors and factory plant engineers.
