The International Standards of the IEC 60364 series specifies the rules for the design, erection, and verification of low-voltage electrical installations. The rules are provided for the safety of human beings (persons), livestock and property against dangers and damage which may arise from the intended use of low-voltage electrical installations and for the proper functioning of those installations. Examples: A non-comprehensive list of electrical installations or systems includes: – residential premises; – commercial premises; – public premises; – industrial premises; – agricultural and horticultural premises; – prefabricated buildings; – caravans, caravan sites and similar sites; – construction sites, exhibitions, fairs and other installations for temporary purposes; – marinas; – external lighting and similar installations; – medical locations; – mobile or transportable units; – photovoltaic systems; – stationary secondary batteries; – low-voltage generating sets. NOTE 1 – “Premises” covers the land and all facilities including buildings belonging to it. The IEC 60364 series covers – circuits supplied at nominal voltages up to and including 1000 V AC or 1500 V DC; For AC, the preferred frequencies which are taken into account in this standard are 5 0 Hz and 60 Hz. The use of other frequencies is not excluded. – circuits, other than the internal wiring of apparatus, operating at voltages exceeding 1000 V AC or 1500 V DC and derived from an installation having a nominal voltage not exceeding 1000 V AC or 1500 V DC, for example, discharge lighting, electrostatic precipitators; – wiring systems and cables not specifically covered by the standards for appliances; – fixed wiring for information and communication technology including power supply, signalling, fibre optic, control and the like (excluding internal wiring of apparatus). The IEC 60364 series applies to: – alterations and/or extensions of the installation; – parts of the existing installation affected by modifications, extensions or alterations; – the design of functional aspects, such as energy efficiency, local production and storage of energy (prosuming). The IEC 60364 series applies to any kind of low-voltage electrical installation or system, except: j) electric traction equipment, including rolling stock and signalling equipment; k) electrical circuits and equipment for automotive purposes within motor vehicles; l) electrical installations of ships and of mobile and fixed offshore units; m) electrical installations in aircraft; n) public street-lighting installations which are part of the public electric power network; o) installations in mines and quarries. Electrical equipment is dealt with only in so far as its selection and application in the installation are concerned. The IEC 60364 series does not apply to the selection and erection of the following electrical equipment: p) radio interference suppression equipment, except where it affects the safety of the installation; q) electric fences; r) external lightning protection systems for buildings (LPS); NOTE 2 – Atmospheric phenomena are covered in IEC 60364-1 but only in so far as effects on the electrical installations are concerned (for example, with respect to selection of surge protective devices). s) electrical equipment of machines. The IEC 60364 series is not intended to apply to low-voltage public distribution networks. NOTE 3 – However, countries can use this standard in whole or in part for that purpose. This applies also to assemblies of electrical equipment complying with the relevant sta ndards.
