Electrical installation calculations: for compliance with BS 7671:2008

This book focuses on worked examples and keeps associated theoretical aspectsto 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 includesimportant 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. The revision also includes information and examples of steel wired armour cables. This includes sufficiency during short circuits and, for cables with externally run CPCs, gives uniqueformulae for calculating more accurate impedance of the armour and external CPC cable during fault conditions.
