Now in its 10th edition, Electrical Installation Calculations: Basic has been updated 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.
