The Overview
Many students have benefited from Advanced Electrical Installation Work in order to achieve in City & Guilds electrical installation awards. This book, presently in its fourth edition, received a thorough overhaul in order to provide an exact match to the Installation route criteria of the 2330 Level 3 Certificate in Electrotechnical Technology. It is also a necessary purchase for students pursuing the Level 3 NVQs in Electrotechnical Services (Electrical Installation – Buildings & Structures).
The 2330 Certificate’s core unit as well as occupational units 2 and 3 in Installation (Buildings & Structures) are all comprehensively covered in Trevor Linsley’s resource for the certificate. Electronic Components, a crucial component of electrical installation work, is covered in a separate chapter that serves as a reference.
This wonderfully illustrated booklet’s worked examples and problems with solutions make for a user-friendly student manual that’s perfect for independent study. New sections on health and safety, employment rights and responsibilities, personal protective equipment, and safety regulations have been introduced to match the 2330 Certificate’s emphasis in these specific areas. The material completely complies with the 2004 IEE Wiring Regulations BS 7671:2001 (incorporating Amendments 1:2002 & 2:2004).
The best-selling book in the category of electrical installation was written by Trevor Linsley, a former senior professor at Blackpool & Fylde College and the head of the NVQ Assessment Center.

This bundle provides the necessary collection of teaching resources and photocopyable handouts for the prerequisite units of the 2330 Certificate in Electrotechnical Technology from City & Guilds, with a chapter-by-chapter match to the units of the electrical installation pathway at Levels 2 and 3. It should be used with the students’ textbooks, together with Basic Electrical Installation Work and Advanced Electrical Installation Work. The basic curriculum for the 2330 syllabus, the two occupational units for Level 3, and the occupational unit for the Level 2 pathway in electrical installation are all covered.
The newly revised edition covers the complete 2330 Level 3 Certificate in Electrotechnical Technology’s Installation route and provides additional treatment of Electronic Components, a crucial area of study for electrical installation.
* Covers subjects that were mentioned in the most recent specifications for the scheme: Regulations pertaining to personal protective equipment, health, and safety
* Adopting the most recent IEE Wiring Regulations, BS 7671:2001, in its entirety.
