Summary:

Brian Scaddan's Electrical Installation Work explains in detail how and why electrical installations are designed, installed and tested.You will be guided in a logical, topic by topic progression through all the areas required to complete the City and Guilds 2357 Diploma in Electrotechnical Technology. Rather than following the order of the syllabus, this approach will make it easy to quickly find and learn all you need to know about individual topics and will make it an invaluable resource after you've completed your course.With a wealth of colour pictures, clear layout, an
