This highly successful book is now updated in line with the Amendment 2-2022 of 18th Edition of the Wiring Regulations. It provides a topic-by-topic progression through the areas of electrical installations, including how and why electrical installations are designed, installed and tested. This tenth edition contains new material on batteries, LED and ELV lighting, data cabling and renewable electricity generation and distribution, with some focus on medical locations, and a glossary of terms. The guidance on tools used and safety legislation has also been brought up to date.

Brian Scaddan's subject-led approach makes this a valuable resource for professionals and students on both City & Guilds and EAL courses. This approach also makes it easy for those who are learning the topic from scratch to get to grips with it independently of any particular course.

The book is widely used in education and training across the UK and has been published for almost 40 years.
