Preface

The 8th Edition of Basic Electrical Installation Work has been completely rewritten in five chapters to closely match the five units of the City and Guilds Level 2 Diploma in Electrical Installations (Building and Structures) (236502).

This book of electrical installation theory and practice will be of value to the electrical trainee working towards:

The City and Guilds 236502 Level 2 Diploma in Electrical Installations (Buildings, and Structures).

The City and Guilds 2365 Level 3 Diploma in Electrical Installations (Building and Structures) (236503).

The EAL Level 3 Diploma in Electrotechnical Services.

The SCOTVEC and BTEC Electrical Utilisation Units at Levels I and II.

Those taking Engineering and Modern Apprenticeship courses.

Basic Electrical Installation Work provides a sound basic knowledge of electrical theory and practice which other trades in the construction industry will find of value, particularly those involved in multi-skilling activities.

The book incorporates the requirements of the latest regulations, particularly:

17th Edition IET Wiring Regulations (Incorporating Amendment 3: 2015);

British Standards BS 7671: 2008 (Incorporating Amendment 3: 2015);

Part P of the Building Regulations, Electrical Safety in Dwellings 2006;

Hazardous Waste Regulations 2005;

Work at Height Regulations 2005.
