Book description
Because this is a book for engineers the practical coverage is reinforced by use of the latest interanational standards, in particular BICSI standards (USA and international) and EU requirements. This will make the book ideal for the large number of industry-based training courses. Coverage has also been matched to the requirements of the revised City & Guilds 3466-04 course.*Covers the real-world issues of selection, design, installation, testing, safety, legislation... neglected by university texts
*An easy-to-read introduction that assumes no prior knowledge beyond basic concepts of voltage and current - ideal for non-specialists as well as practitioners
*Covers new BICSI (US / international) regulations and EU framework
