| Wiring Systems and Fault Finding for Installation Electricians |
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 color 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.
