Low-voltage switchgear and controlgear assemblies - Part 4: Particular requirements for assemblies for construction sites (ACS)
Defines the specific requirements of assemblies for construction sites (ACS) as follows: assemblies for which the rated voltage does not exceed 1 000 V in case of a.c. or 1 500 V in case of d.c.; assemblies where the nominal primary voltage and the nominal secondary voltage of transformers incorporated in ACS are within the limits specified above; assemblies intended for use on construction sites, both indoors and outdoors; transportable (semi-fixed) or mobile assemblies with enclosure. The manufacture and/or assembly may be carried out other than by the original manufacturer. It is to be read in conjunction with AS/NZS 61439.1:2016. Adopted with national modifications from IEC 61439-4, Ed. 1.0 (2012).
