Book Description
Manual calculations are still extensively used and in particular are necessary for checking and verifying various software calculation design packages. It is highly recommended that users of such software familiarise themselves with the rudiments of these calculations prior to using the software packages. This essential book fills the gap between software and manual calculations. It provides the reader with all the necessary tools to enable accurate calculations of circuit designs. Rather than complex equations, this book uses extensive worked examples to make understanding the calculations simpler. The focus on worked examples furnishes the reader with the knowledge to carry out the necessary checks to electrical cable sizing software programmes. Other key features include: Updated information on 230 volt references and voltage drop under normal load conditions New sections on buried cables that take into account soil thermal conductivity, trenches and grouping, allowing readers to carry out accurate cables sizing Information and examples of steel wired armour cables, new to this edition. This includes sufficiency during short circuits and, for cables with externally run CPCs, gives unique fault conditions. Covers calculations of cross-sectional areas of circuit live conductors Earth fault loop impedances Protective conductor cross-sectional areas and short circuit conditions Short circuit protection. The last chapter combines all of the calculations of the previous chapters to enable the reader to complete an accurate design of an installation circuit under all conditions. A unique tool for detailed electrical installation trade, Electrical Installation Calculations, Fourth Edition is invaluable to electricians, electrical designers, installers, technicians, contractors, and plant engineers. Senior electrical engineering students and technical colleges, junior engineers, and contracts managers will also find this text useful.

Book Description
This book provides guidance on how to carry out the calculations required for circuit designs in compliance with the Wiring Regulations. It has been updated to take account of changes introduced by BS 7671 : 2001 and Amendment 1 to the standard which included a new table of current-carrying capacities. The book makes extensive use of worked examples with the minimum discussion of theory. Chapters cover: ? cross-sectional areas of circuit live conductors ? voltage drop under normal load conditions ? earth fault loop impedances ? protective conductor cross-sectional areas ? short circuit conditions The final chapter combines all the calculations of the previous chapters, to enable the reader to achieve the complete design of a circuit. Published on behalf of the Electrical Contractors' Association, the book filled a significant gap when it was first published. It will continue to be invaluable for all electrical contractors, as well as for plant engineers and students.

Book Description
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

Pages : 275

Book Description
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.
