FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60364-7-740 has been prepared by IEC technical committee 64:
Electrical installations and protection against electric shock.
The text of this standard is based on the following documents:
FDIS Report on voting
64/1132/FDIS 64/1161/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
The committee has decided that the contents of this publication will remain unchanged
until 2006. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition; or
• amended.

INTRODUCTION
The requirements of this part of IEC 60364 supplement, modify or replace certain of the
general requirements of IEC 60364.
The clause numbering follows the pattern and corresponding references of IEC 60364.
The numbers following the particular number of part 7-740 are those of the corresponding parts
or clauses of IEC 60364.
The absence of reference to a chapter, a section or a clause means that the corresponding
general requirements of IEC 60364 are applicable.

ELECTRICAL INSTALLATIONS OF BUILDINGS –
Part 7-740: Requirements for special installations or locations –
Temporary electrical installations for structures, amusement devices
and booths at fairgrounds, amusement parks and circuses
740.1 Scope, object and fundamental principles
740.1.1 Scope
This part of IEC 60364 specifies the minimum electrical installation requirements to facilitate
the safe design, installation and operation of mobile, temporarily or permanently installed
electrical machines and structures which incorporate electrical equipment. The machines and
structures are intended to be installed repeatedly, without loss of safety, temporarily or
permanently, at fairgrounds, amusement parks, circuses or any other places.
For non-electrical safety, refer to CEN TC 152.
The object of this part of IEC 60364 is to define the electrical installation requirements for such
structures and machines, both being either integral parts or constituting the total amusement
device.
This part does not apply to the electrical equipment of machines (see IEC 60204-1).
740.1.2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this part of IEC 60364. For dated references, subsequent amendments
to, or revisions of, any of these publications do not apply. However, parties to agreements
based on this part of IEC 60364 are encouraged to investigate the possibility of applying the
most recent editions of the normative documents indicated below. For undated references, the
latest edition of the normative document referred to applies. Members of IEC and ISO maintain
registers of currently valid normative documents.
