Designed to provide a step-by-step guide to successful application of the electrical installation calculations required in day-to-day electrical engineering practice, the Electrical Installation Calculations series has proved an invaluable reference for over forty years, for both apprentices and professional electrical installation engineers alike.

Now in its seventh edition, Volume 2 has been fully updated in line with the 17th Edition IEE Wiring Regulations (BS 7671:2008) and references the material covered to the Wiring Regs throughout. The content meets the requirements of the 2330 Level 3 Certificate in Electrotechnical Technology from City & Guilds and will also prove a vital purchase for those undertaking Level 3 NVQs in Electrotechnical Services. Essential calculations which may not necessarily feature as part of the requirements of the syllabus are retained for reference by professional electrical installation engineers based in industry, or for those students wishing to progress to higher levels of study.

The book’s structure and new design make finding the required calculation easy. Key terms are explained in a glossary section and worked examples and exercises are included throughout the text to maximise accessibility of the material for the reader. A complete question and answer section is included at the back of the book to enable readers to check their understanding of the calculations presented.

Also available: Electrical Installation Calculations Volume 1, 8th edn, by Watkins & Kitcher- the basic calculations required for electrical installation work, and Level 2 study and apprenticeships.

* The established series for carrying out correct electrical installation calculations - continuously in print for over 40 years
* New edition fully up-to-date with 17th Edition IEE Wiring Regulations
* Matched to the requirements of the City & Guilds Level 3 Certificate in Electrotechnical Technology (2330)

Arvustused

"A very useful study aid, the book is ideal for those who have become a little rusty with their calculations and need to remind themselves of the basics." Amazon.co.uk customer review
