Introduction
The requirements of this part of IEC 60364 modify or replace certain of the general requirements of
IEC 60364.
The clause numbering of part 7-711 follows the pattern and corresponding references of IEC 60364.
The numbers following the particular number of part 7-711 are those of the corresponding parts or clauses
of IEC 60364.
The absence of reference to a part or a clause means that the general requirements of IEC 60364 are
applicable.
Numbering in parentheses corresponds to the numbering of the “non restructured” IEC 60364 dated
before 2002.

711 Exhibitions, shows and stands
711.1 Scope, object and fundamental principles
711.1.1 Scope
The particular requirements of this part of IEC 60364, in association with IEC 60364, parts 1 to 6, apply to
the temporary electrical installations in exhibitions, shows and stands (including mobile and portable
displays and equipment) to protect users.
Unless specifically stated, this part does not apply to exhibits for which requirements are given in the
relevant standards.
This part does not apply to the fixed electrical installation of the building, if any, in which the exhibition,
shows or stands may take place.

See Annex ZA.
711.2 Definitions
For the purpose of this part of IEC 60364, the following definitions apply.
711.2.1
exhibition
event intended for the purpose of displaying and/or selling products etc., which can take place in any
suitable location, either a room, building or temporary structure
711.2.2
show
display or performance in any suitable location, either a room, building or temporary structure
711.2.3
stand
area or temporary structure used for display, marketing, sales, entertainment etc.

a unit or a part of a unit including mobile portable units, situated indoors or outdoors, designed and
intended to be assembled and dismantled
711.2.5

711.3 (711.30) Assessment of general characteristics
711.313 Supplies
The nominal supply voltage of temporary electrical installations in exhibitions, shows and stands shall not
exceed 230/400 a.c. or 500 V d.c.
711.32 (711.5.512.2) Classification of external influences
The external influence conditions of the particular location where temporary electrical installations are
erected, e.g. presence of water, mechanical stresses, shall be taken into account.
711.4 Protection for safety
711.41 Protection against electric shock
711.413 Protection against indirect contact
711.413.1 Protection by automatic disconnection of supply
711.413.1.3 TN system
Where the type of system earthing is TN, the installation shall be TN-S.
[subclause 711.413.1.3.4 deleted]
711.413.1.6 Supplementary equipotential bonding
[subclause 711.413.1.6.1 deleted]
711.413.1.6.2 The extraneous-conductive-parts of a vehicle, wagon, caravan or container shall be
bonded to the protective conductor of the installation in more than one place if the type of construction
does not ensure continuity. The nominal cross-sectional area of conductors used for this purpose shall be
not less than 4 mm² copper.
If the vehicle, wagon, caravan or container is made substantially of insulating material, these requirements
do not apply to metal parts which are unlikely to become live in the event of a fault.
711.42 Protection against thermal effects
711.42.01
NOTE Attention is drawn to the increased risk of fire and burns in these locations and the need to comply with the requirements of
IEC 60364-4-42.
711.42.02 Where SELV or PELV is used, the protection of conductors shall be provided by insulation
capable of withstanding a test voltage of 500 V a.c. for 1 min, or by barriers or enclosures affording a
degree of protection of at least IP4X or IPXXD.

711.462.5 (711.5.536.2.3) Every separate temporary structure, such as a vehicle, a stand or a unit,
intended to be occupied by one specific user and each distribution circuit supplying outdoor installations
shall be provided with their own readily accessible and properly identifiable means of isolation. The means
of isolation shall be selected and erected in accordance with IEC 60364-5-537, clause 537.2. Switches,
circuit-breakers, residual current devices etc. considered suitable for isolation by the relevant IEC
standards may be used.
711.47 Application of protective measures for safety
711.471 Measures of protection against electric shock
711.471.1 (711.4.410.3.2.1) Protection against electric shock in normal service

and by placing out of reach (see IEC 60364-4-41, clause 412.4) shall not be used.
711.471.2 (711.4.410.3.3) Protection against electric shock in case of a fault
Protective measures against indirect contact by non-conducting location (see IEC 60364-4-41,
clause 413.3) and by earth-free equipotential bonding (see IEC 60364-4-41, clause 413.4) shall not be
used.
711.48 Choice of protective measures as a function of external influences
711.481.3.1.3 (711.4.410.3.4.3)
 Cables intended to supply temporary structures should be protected at
their origin by residual current devices whose rated residual operating current does not exceed 300 mA.
These devices shall provide a delay by using a device in accordance with IEC 60947-2, or be of the
S-type in accordance with IEC 61008-1 or IEC 61009-1 for discrimination with RCDs protecting final
circuits.
NOTE The recommendation for additional protection relates to the increased risk damage to cables in temporary locations.
