Textbook of electrical installation work

From my copy. Preface This is the first of a series of books written to cover the "A", "B", and "C" Courses in electrical installation work of the City and Guild of London. It is hoped, however, that they will prove of some value to those who desire to further their knowledge of the electrical installation industry. If the emphasis has been towards the "B" and "C" certificate work, it is because it is felt that the "B" certificate is the minimum requirement the electrician should possess, especially if he wishes to work on three phase supplies. The authors would like to thank all those firms who have so kindly helped with material and illustrations, and due acknowledgement has been made in the appropriate places. Many of the problems worked in the text and also those examples at the end of each chapter for the student to work out for himself have been taken from the various examining bodies, especially the City and Guild, to whom the authors express their grateful thanks. They would also like to express their thanks to those colleagues, and students, who have so kindly given them assstance and advice. R. A. MEE. E. A. REEVES.
