Electrical Installation Work


Electrical Installation Work 

Electrical Installation Work

This book is intended for the trainee electrician who is working towards NVQs, gaining competences in
various aspects of installation work.
It covers both installation theory and practice in compliance with the 18th edition of the IET Wiring
Regulations, and also deals with the electrical contracting industry, the environmental effects of electricity
and basic electronics.

The material in this book has been arranged to cater for student-centred learning programmes. Self-
assessment questions and answers are provided at the end of chapters.

Since January 1995, the United Kingdom distribution declared voltages at consumer supply terminals have
changed from 415V/240V +6%/–6% to 400V/230V +10%/–6%. As there has been no physical change
to the system, it is likely that measurement of voltages will reveal little or no difference to those before,
nor will they do so for some considerable time to come. However, I have used only the new values in the
examples in this book.
