Electrical Installation Calculations
For Compliance with BS 7671:2008
von Mark Coates und B. D. JenkinsManual calculations are still extensively used and in particularare necessary for checking and verifying various softwarecalculation design packages. It is highly recommended that users ofsuch software familiarise themselves with the rudiments of thesecalculations prior to using the software packages.
This essential book fills the gap between software and manualcalculations. It provides the reader with all the necessary toolsto enable accurate calculations of circuit designs. Rather thancomplex equations, this book uses extensive worked examples to makeunderstanding the calculations simpler. The focus on workedexamples furnishes the reader with the knowledge to carry out thenecessary checks to electrical cable sizing softwareprogrammes.
Other key features include:
* Updated information on 230 volt references and voltage dropunder normal load conditions
* New sections on buried cables that take into account soilthermal conductivity, trenches and grouping, allowing readers tocarry out accurate cables sizing
* Information and examples of steel wired armour cables, new tothis edition. This includes sufficiency during short circuits and, for cables with externally run CPCs, gives unique faultconditions.
* Covers calculations of cross-sectional areas of circuit liveconductors
* Earth fault loop impedances
* Protective conductor cross-sectional areas and short circuitconditions
* Short circuit protection.
The last chapter combines all of the calculations of theprevious chapters to enable the reader to complete an accuratedesign of an installation circuit under all conditions.
A unique tool for detailed electrical installation trade, Electrical Installation Calculations, Fourth Edition isinvaluable to electricians, electrical designers, installers, technicians, contractors, and plant engineers. Senior electricalengineering students and technical colleges, junior engineers, andcontracts managers will also find this text useful.
