Purpose of initial verification and periodic inspection, reasons for inspection and testing, comparing the two processes, the documents issued (EIC, MEIWC, EICR and their schedules), statutory and non-statutory documents, the information needed to agree extent, limitations and sampling, signatory responsibilities, and recording and retention (13 of the 60 questions)

Health and safety requirements when inspecting and testing, the relevant requirements of the Electricity at Work Regulations 1989, the safe isolation procedure to HSE guidance, why safe isolation is carried out and the implications of omitting it (3 of the 60 questions)
