This book deals with an area of practice that many students and non-electricians find particularly challenging. It explains how to interpret circuit diagrams, wiring systems, and outlines the principles of testing before explaining how to apply this knowledge to fault finding in electrical circuits.

A handy pocket guide for anybody that needs to be able to trace faults in circuits, whether in domestic, commercial or industrial settings, this book will be extremely useful to electricians, plumbers, heating engineers and intruder alarm installers.
