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.

711.1.1 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.
711.1.2 Normative references
See Annex ZA.
711.2 Definitions

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

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 (711.5.536.2) Isolation
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.

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

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.
711.481.3.1.4 (711.4.410.3.4.3) All circuits for socket-outlets rated up to 32 A and all final circuits other
than for emergency lighting shall be protected by an RCD with a rated residual operating current not
exceeding 30 mA.
711.482 (711.4.422) Protection against fire
711.482.2.8 (711.4.422.3.8) A motor which is automatically or remotely controlled and which is not
continually supervised shall be fitted with a manual reset protective device against excess temperature.
711.482.3.2 (711.4.422.4.2) Heat generation
Lighting equipment such as incandescent lamps, spotlights and small projectors, and other equipment or
appliances with high temperature surfaces shall be suitably guarded, and installed and located in
accordance with the relevant standard. All such equipment shall be arranged well away from combustible
material to prevent contact.
Showcases and signs shall be constructed of material having an adequate heat resistance, mechanical
strength, electrical insulation and ventilation, taking into account the combustibility of exhibits in relation to
the heat generation.
Stand installations containing a concentration of electrical apparatus, lighting fittings or lamps liable to
generate excessive heat shall not be installed unless adequate ventilation provisions are made, e.g. well-
ventilated ceiling constructed of incombustible material.
In all cases, the manufacturers’ instructions shall be followed.
711.5 Selection and erection of electrical equipment
711.51 Common rules
Control and protective switchgear shall be placed in closed cabinets which can only be opened by the use
of a key or a tool, except for those parts designed and intended to be operated by ordinary persons (BA1)
as defined in IEC 60364-3, clause 322.1.
[clause 711.514 deleted]
711.52 Wiring systems
Armoured cables or cables protected against mechanical damage shall be used wherever there is a risk of
mechanical damage.
Wiring cables shall be copper and have a minimum cross-sectional area of 1.5 mm², and they shall
comply with IEC 60227 or IEC 60245 as appropriate.
Flexible cords shall not be laid in areas accessible to the public unless they are protected against
mechanical damages.
711.521 Types of wiring systems
Where no fire alarm system is installed in a building used for exhibitions etc. cable systems shall be either
- flame retardant to IEC 60332-1 or IEC 60332-3, and low smoke to IEC 61034
or
-
single or multicore unarmoured cables enclosed in metallic or non-metallic conduit or trunking,
providing fire protection
