This popular guide focuses on common misconceptions in the application of the IET Wiring Regulations. It explains in clear language those parts of the regulations that most need simplifying, outlining the correct procedures to follow and those to avoid. Emphasis has been placed on areas where confusion and misinterpretation are common, such as earthing and bonding, circuit design and protection, and in particular the increased use of RCDs.

With the coverage carefully matched to the syllabus of the City & Guilds Certificate in the Requirements for Electrical Installations (2382-12 and 2382-15) and containing sample exam questions and answers, this book is also an ideal revision guide.
