About Of The Book :
The aim of this book is to help the reader to approach the drawing
and interpretation of electrical diagrams with confidence, to understand the principles of testing and to apply this knowledge to fault
finding in electrical circuits.
The abundant colour diagrams with associated comments and explanations lead from the basic symbols and simple circuit and wiring diagrams, through more complex circuitry, to specific types of wiring
systems and, finally, to the methodical approach to fault finding.
The new edition has been brought fully in line with the 17th Edition
IET Wiring Regulations.
