Chichester, West Sussex, UK : Wiley-Blackwell, 2010 xix, 192 p. : ill. ; 25 cm. Includes index "This book focuses on worked examples and keeps associated theoretical aspects to a minimum, furnishing the reader with the knowledge to carry out the necessary checks to electrical cable sizing software programmes. The book covers cross-sectional areas of circuit live conductors, voltage drop under normal load conditions, and earth fault loop impendances. It also has chapters on protective conductor cross-sectional areas and 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. This fourth edition includes important changes that take into account the 2008 updates to the BSI wiring regulations. It will be the first book on electrical installation calculations specifically, to incorporate these modifications. Fully revised to reflect the changes in the 17th edition of the wiring regulations (published June 2008), including updated information on 230 volt references. Includes new sections on buried cables that take into account soil thermal conductivity, trenches and grouping, allowing readers to carry out accurate cables sizing. Supplies information and examples of steel wired armour cables, also new to this edition."-- Provided by publisher.
