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 working in a non-supervisory capacity, as well as newcomers to the industry, all of whom are involved in inspecting and testing electrical installations, and need to ensure their work complies with the latest version of the Wiring Regulations. This text is a practical guide to the current inspection and testing requirements in electrical installation, and is written specifically for the City & Guilds 2391 vocational award — the next step for anyone with a 2381 qualification, advancing technical knowledge without the supervisory emphasis of the 2400. The new edition is updated throughout to match the 2004 version of BS 7671:2001 (incorporating Amendments 1:2002 & 2:2004), and is supported by a sample test paper, complete with model answers and mark scheme. The fifth edition also provides essential information on the completion of electrical installation certificates, with a step-by-step guide on the entries that need to be made and where to source data.
