This book has for many years been the standard guide to the practical aspects of domestic electrical wiring. It explains step-by-step what needs to be done so that work can be carried out safely and correctly first time. The thirteenth edition has been fully updated in line with the 17th Edition Wiring Regulations and latest best practice. It is essential reading for anyone obtaining a Domestic Installer Scheme Qualification which relates to Part P of the Building Regulations. The handy format and clear, straightforward text have also made this book popular as a quick guide to best practice for electricians. Although it is not intended as a DIY manual, non-qualified persons will also find the book useful before calling in qualified operatives.
