This popular guide clarifies the requirements for inspection and testing, explaining in clear language those parts of the IET 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 content suitable for both City & Guilds and EAL Inspection and Testing courses and containing a sample MCQ paper and answers, it is also an ideal revision guide.
