This well-known textbook is written for all electrical trainees who want to understand not only how, but why electrical installations are designed, installed and tested in particular ways. Brian Scaddan's approach encourages independent learning with end of chapter self-assessment questions provided. The material is arranged into logical topic sections rather than following a particular syllabus. This makes the book a handy reference even after the course. However, the book meets the requirements of both Level 2 and 3 of the City & Guilds 2330 Certificate and the Level 3 2356 NVQ and a mapping grid to the learning outcomes is included. The new edition is fully in line with the 17th IEE Edition Wiring Regulations. In addition, the new full colour page design will help make learning easier for students of all abilities.
