LOW-VOLTAGE SWITCHGEAR AND
CONTROLGEAR ASSEMBLIES –

Part 4: Particular requirements for assemblies
for construction sites (ACS)

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61439-4 has been prepared by subcommittee 17D: Low-voltage
switchgear and controlgear assemblies, of IEC technical committee 17: Switchgear and
controlgear.
This first edition of IEC 61439-4 cancels and replaces the second edition of IEC 60439-4
(2004), and constitutes a technical revision.
This edition includes the following significant technical changes with respect to the last edition
of IEC 60439-4:
• modification of the title as “Part 4: Particular requirements for assemblies for construction
sites (ACS)”
• alignment on IEC 61439-1 regarding the structure and technical content, as applicable;
• to allow comparison with tested ACS.

LOW-VOLTAGE SWITCHGEAR AND
CONTROLGEAR ASSEMBLIES –

Part 4: Particular requirements for assemblies
for construction sites (ACS)



1 Scope
NOTE Throughout this standard, the abbreviation ACS (ASSEMBLY for construction site, see 3.1.101) is used for
a low-voltage switchgear and controlgear assembly intended for use on construction and similar sites.
This part of 61439 defines the specific requirements of 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, 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;
– transportable (semi-fixed) or mobile ASSEMBLIES with enclosure.
The manufacture and/or assembly may be carried out other than by the original manufacturer.
This standard does not apply to individual devices and self-contained components, such as
motor starters, fuse switches, electronic equipment, etc. which will comply with the relevant
product standards.
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.).
Requirements for electrical protection provided by equipment manufactured according to this
International Standard are given in IEC 60364-7-704.
