✦ Synopsis

• Fully up-to-date with the latest amendments to the 17th Edition of the IET Wiring Regulations
• Simplifies the advice found in the Wiring Regulations, explaining how they apply to working practice for inspection, testing and certification
• Expert advice from an engineering training consultant, supported with colour diagrams, examples and key data

This popular guide clarifies the requirements for inspection and testing, explaining in clear language those parts of the Wiring Regulations that most need simplifying. In addition to the descriptive and diagrammatic test methods that are required, explanations of the theory and reasoning behind test procedures are given, together with useful tables for the comparison of test results. The book 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.

With the coverage carefully matched to the syllabus of the City & Guilds Certificates in Inspection, Testing and Certification of Electrical Installations (2394 and 2395) and Fundamental Inspection, Testing and Initial Verification (2392-10), and containing sample papers and suggested solutions, it is also an ideal revision guide.
