ABB Electrical installation handbook 6th edition 2010

The scope of this electrical installation handbook is to provide the designer and
user of electrical plants with a quick reference, immediate-use working tool. This
is not intended to be a theoretical document, nor a technical catalogue, but, in
addition to the latter, aims to be of help in the correct definition of equipment,
in numerous practical installation situations.
The dimensioning of an electrical plant requires knowledge of different factors
relating to, for example, installation utilities, the electrical conductors and other
components; this knowledge leads the design engineer to consult numerous
documents and technical catalogues. This electrical installation handbook, however, aims to supply, in a single document, tables for the quick definition of the
main parameters of the components of an electrical plant and for the selection
of the protection devices for a wide range of installations. Some application
examples are included to aid comprehension of the selection tables.
