Introduction to Electrical Installation Work follows the unit structure of the City & Guilds 2330 Level 2 Certificate in Electrotechnical Technology (installation route), covering the three core units of the scheme, along with the Occupational Unit 4 'Installation (Buildings &Structures)'. But this book will prove a vital purchase for any student on first year electrical courses as well as for those in related trades in the construction industry. Formerly Senior Lecturer at Blackpool & Fylde College, as well as Head of the NVQ Assessment Centre, Trevor Linsley is a best-selling author in electrical installation.
