ABSTRACT
This chapter helps the readers to understand the procedures for the in-service inspection and testing of electrical equipment. The learning outcome is specifically designed to test our knowledge of the various laws and documents relating to electrical equipment maintenance. There are a number of areas within the IET Code of Practice to provide information relating to the learning outcome. The IET Code of Practice lists and gives some information on the key statutory documents relating to portable appliance testing and expands on areas such as scope, responsibility and maintenance. The chapter provides assessment criteria for portable appliance testing: to identify the types of in-service inspection and testing, state the factors which determine the initial frequency of inspecting and testing and to identify the initial frequencies of inspection and testing of equipment. The criteria relates to the types of in-service inspection and testing, which essentially break down into three areas: user check, formal visual inspection and combined inspection and test.
