A good book for anyone studying for City & Guilds 2391, 2392, 2330 level 3 or just wanting to know more about testing.
The book is written with the practicing electrician in mind. Some of the tips given in this book are unique to this author and demonstrate that he knows his subject. Advice for passing the inspection and testing exams is spot on.
All though the book does contain some minor errors, and some of the references have not been fully updated to reflect changes in the 17th Edition of the Wiring Regulations, the postive points far outway the negative and you would have to go a long way to find a book on inspection and testing that comes anywhere near this book.
