Brian Scaddan's guides to the IEE Wiring Regulations have established themselves as an industry standard. This new edition will be an essential reference for all contractors, technicians and other professionals, as well as newcomers to the industry, who need to ensure their work complies with the latest version of the Wiring Regulations. Used alongside the regulations themselves, this book is the key to safe and efficient electrical installation. The book is also a concise and popular text for the City & Guilds 2381 syllabus. The new edition is updated throughout to match the 2004 version of BS 7671:2001 (incorporating Amendments 1:2002 & 2:2004), and also features extended coverage of Special Locations (such as bathrooms, construction sites and computer / data type installations). There are common misconceptions in the application of the Wiring Regulations in these areas with regard to bonding, voltages, disconnection times and sizes of earthing conductors.
