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.
