Preface 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 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 IEE Wiring Regulations.

Description Of Each Chapter:
CHAPTER 1 Diagrams:
This is an area often overlooked or even ignored. The IEE Wiring Regulations require that ‘diagrams, charts, tables or equivalent forms of information are made available ’ to the installer and inspector and tester.
CHAPTER 2 Wiring Systems:
In this chapter we will investigate a selection of the many wiring systems employed in modern installations. Some of these systems are simple to understand and require little explanation. Others of a more complex nature should now, in the light of the reader’s newfound knowledge of diagrams, etc., present only minor problems of interpretation.
CHAPTER 3 Testing and Test Instruments:
Whilst this section deals with testing, it should be remembered that such action should always be preceded by inspection as this may reveal faults, damage, deterioration, etc., that cannot be detected by testing alone.
CHAPTER 4 Fault Finding:
Starting this chapter has been as difficult as finding a fault on a complex system. The old adage of ‘start at the beginning and finish at the end ’ is all right for storytellers or authors of technical books, but is not always sensible for fault finders! Perhaps it would be wise to begin by determining what exactly a fault is.
A fault is probably best defined as a disturbance in an electrical system of such magnitude as to cause a malfunction of that system. It must be remembered, of course, that such disturbances may be the secondary effects of mechanical damage or equipment failure.
Actual electrical faults, or should one say faults that are caused by ‘electricity ’, are rare and are confined in the main to bad design and/or installation or deterioration and ageing. However, all of this still does little to indicate where to begin looking for a fault. Only experience will allow one to pinpoint the exact seat of a breakdown, but a logical approach to fault finding will save a great deal of time and frustration.
