ABSTRACT

All the essential calculations required for advanced electrical installation work

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

  • A step-by-step guide to everyday calculations used on the job
  • An essential aid to the City & Guilds certificates at Levels 2 and 3
  • For apprentices and electrical installation engineers

Now in its eighth edition, this book is in line with the amendments to the 17th Edition IET Wiring Regulations (BS 7671:2008) and references the material covered in the Wiring Regulations throughout. The content also meets the requirements of the latest Level 3 Diploma qualifications from City & Guilds (including the 2365 and 2357). Essential calculations which may not necessarily feature as part of the requirements of the syllabus are retained for electrical installation engineers and students wishing to progress to higher levels of study.

Key terms are explained in a glossary section and worked examples and exercises are included throughout the text. 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.
