Wiring Systems and Fault Finding - For Installation Electricians

Brian Scaddan

ISBN 0750659238
Pages 128

Description
Wiring Systems and Fault Finding for Installation Electricians is a handy reference guide that deals with an area of practice which many students and technicians find particularly challenging. The readership of this book includes installation and plumbing contractors, heating engineers, and anyone who needs to be able to trace faults in circuits, whether they be in domestic, commercial or industrial systems. Coverage includes the interpretation of circuit diagrams, wiring systems, and the principles and practice of testing and fault diagnosis. Applications focused on include heating systems and intruder alarms.

The third edition of this popular guide has updated and expanded coverage of testing and fault-finding techniques. New sections cover shock risk, safe isolation, and basic electrical theory. It has also been brought into line with the latest revisions to the IEE Wiring Regulations (BS7671:2001).

Brian Scaddan is a Chief Examiner and Honorary Member of City and Guilds. He has over 30 years' experience in Further Education, and is now Director of Brian Scaddan Associates, Engineering Training Consultants. He is a leading author of books on electrical installation, inspection and testing, including IEE Wiring Regulations: Explained and Illustrated and Electrical Installation Work.
