The legal requirements for regular testing of all electrical equipment in work environments and public places have made testing a major growth area for electricians over recent years. Many staff without electrical training, such as maintenance staff and caretakers, are also being nominated by their employers to carry out electrical safety testing.This book is ideal for electricians administering PAT, and non-specialists following a City and Guilds course. It has been written specifically to meet the demands of the City and Guilds 2377 exam, and is the only available text for this course. The book contains an appendix providing the electrical fundamentals needed by non-specialists, but it is also an essential reference guide for anyone – technician or manager – with responsibility for PAT.
