Wiring Systems and Fault Finding for Installation Electricians by Brian Scaddan
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 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 system and, finally, to the methodical approach to fault finding.
