Reference EN 60439-4:2004
Title Low-voltage switchgear and controlgear assemblies - Part 4: Particular requirements for assemblies for construction sites (ACS)
Project Number 15631
Abstract/Scope Applies to type-tested ASSEMBLIES (TTA) intended for use on construction sites, i.e. temporary places of work to which the public do not generally have access and where building construction, installation, repairs, alteration or demolition of property (buildings) or civil engineering (public works) or excavation or any other similar operations are carried out. These ASSEMBLIES may be transportable (semi-fixed) or mobile. This standard does not apply to ASSEMBLIES for use in the administrative centres of construction sites (offices, cloakrooms, ASSEMBLY rooms, canteens, restaurants, dormitories, toilets, etc.). The nominal primary voltage and the nominal secondary voltage of transformers incorporated in ACS shall be within the limits specified in EN 60439-1. Requirements for electrical protection provided by equipment manufactured according to this International Standard shall comply with the requirements given in EN 60364-7-704. NOTE: This standard may be used as a guide to partially type-tested ASSEMBLIES (PTTA) constructed according to agreement between manufacturer and user taking into account the nature of supply and/or distribution network and relevant installation requirements. The following major changes with respect to edition 1 (including amendments 1 and 2) have been incorporated: - introduction of the definition for rated current of ACS; - replacement of classification based on the rated current of ACS by classification based on the function as assigned by the manufacturer; - amended requirements for the protection of socket-outlets with reference to the more comprehensive requirements of EN 60364-7-704; - introduction of common requirements for all types of ACS.
