Electrical Installation Calculations: Basic 9th Edition by Christopher Kitcher.
Mathematics forms the essential foundation of electrical installation work. Without applying mathematical functions we would be unable to work out the size of a room which needs lighting or heating, the size and/or the number of the lights or heaters themselves, the number and/or the strength of the fixings required, or the size of the cables supplying them. We would be unable to accurately establish the rating of the fuse or circuit breaker needed to protect the circuits, or predict the necessary test results when testing the installation. Lik it or not you will need to be able to carry out mathematics if you want to be an efficient and skilled electrician. This book will show you how to perform the maths you will need to be a proficient electrician. It concentrates on the electronic calculator methods you would use in class and in the workplace.
The book does not require you to have a deep understanding of how the mathematical calculations are performed – you are taken through each topic step by step, then you are given the opportunity yourself to carry out exercises at the end of each chapter. Throughout the book useful references are made to the 17th edition of BS 7671:2008 Electrical Wiring Regulations and the 17th Edition IEE On-Site Guide. Simple cable selection methods are covered comprehensively in this volume so as to make it a useful tool for tradesmen involved in Part P of the building regulations, with more advanced calculations being added in the companion volume, Electrical Installation Calculations: Advanced Electrical Installation Calculations: Basic originally written by A.J.Watkins and R.K. Parton has been the preferred book for students looking to gain an understanding of electrical theory and calculations for many years. This edition has been updated so that the calculations and explanations comply with the 17th edition wiring regulations. Also included in this new edition are a number of questions and exercises, along with answers to assist students who are intending to study for the City & Guilds 2330 Gola exams. Chris Kitcher
