ABB - Electrical Installation Handbook PART II
ABB – Electrical Installation Handbook PART II

Scope and objectives

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.


Selection of the cable

The international reference Standard ruling the installation and calculation of the current carrying capacity of cables in residential and industrial buildings is IEC 60364-5-52 “Electrical installations of buildings – Part 5-52 Selection and Erection of Electrical Equipment- Wiring systems”.

The following parameters are used to select the cable type:

Conductive material (copper or aluminium):

The choice depends on cost, dimension and weight requirements, resistance to corrosive environments (chemical reagents or oxidizing elements).

In general, the carrying capacity of a copper conductor is about 30% greater than the carrying capacity of an aluminium conductor of the same cross section. An aluminium conductor of the same cross section has an electrical resistance about 60% higher and a weight half to one third lower than a copper conductor.

Insulation material (none, PVC, XLPE-EPR):

The insulation material affects the maximum temperature under normal and short-circuit conditions and therefore the exploitation of the conductor cross section (see Chapter 2.4 “Protection against short-circuit”).

Type of conductor:

The type of conductor (bare conductor, single-core cable without sheath, singlecore cable with sheath, multi-core cable) is selected according to mechanical resistance, degree of insulation and difficulty of installation (bends, joints along the route, barriers…) required by the method of  installation.
