Electrical Installation Calculations: Basic - 10th Edition

Now in its 10th edition, Electrical Installation Calculations: Basic has been up-
dated to include any changes required to bring it in line with the 18th edition
of the IET electrical wiring regulations (BS7671:2018).
Electrical calculations required for exams can prove difficult to master, but for
more than 40 years, this book series has proved very helpful to students and
professional electrical engineers studying for electrical qualifications. It covers
all the calculations required for Level 2 electrical qualifications, along with
other useful calculations that may be used in the electrical industry but may
not feature in the syllabus of some exams.
Although the calculations in this book are referred to as ‘basic’, they form the
foundation of all calculations carried out in the electrical industry, which have
been set out simply with worked examples along with additional questions
and answers. Key terms are explained in a glossary, which can be used to assist
with the reader’s understanding.
Christopher Kitcher has been working in the electrical industry for 60 years,
many of which have been spent working on site. The last 20 years have entailed
teaching and training at various colleges and companies. He is the author of
Electricians' On-Site Companion (Routledge, 2017), Practical Guide to Inspec-
tion, Testing and Certification of Electrical Installations (Routledge, 2018), and
Electrical Installation Calculations: Advanced (Routledge, 2022).
