This is the first of three volumes dealing with electrical installation calculations. Designed as a guide for trainee electricians, it contains worked examples of the calculations needed for the City and Guilds course. The new editions have been fully revised and updated to fit the syllabus.

'Electrical Installation Calculations' is the essential 3 volume guide for trainee electricians, containing worked examples of the calculations needed for City & Guilds courses (2380, 2391, 2400 & 2351) in electrical installation. Each new edition takes full account of the second amendment made in 1997 to British Sandards BS7671:1992; changes to C&G 236 Parts 1 & 2 syllabus; and changes to the national standard voltages (415/240V to 400/230V). The installation calculations have been updated and the exercises rewritten to incorporate the changes in the voltages. The text now covers all electrical installation courses (C7G 2380, 2391 and 2400) and the material has been reorganised to better fit the syllabus topic areas.
