I would characterize this book by saying that rather address is for beginners or professionals in electricity CAP students, rather than amateurs. All the problems of electricity of the building are addressed. All wiring diagrams are there. This is a very good investment for the services it renders you. Perfect for the electrician who has already seen some basics in progress. It is an ideal complement to the electrical courses for those who want to work within the standards.
This book does not deal with industrial electricity.
