Rules & regulations

• The installation of electrical power onto stands and other temporary structures and facilities, must be undertaken by the venue appointed electrical contractor. The nominated contractor will liaise with the exhibitor or contractor to ensure that the installation is verified as safe prior to it being connected
• Details of the power supply available at the venue and the detailed requirements for each stand type are listed in the power supply section of this event manual. This information includes the voltages and the number of socket outlets which will normally be provided. The venue and stands power supplies will be protected by 30mA residual current and over current protection. In these circumstances, should the supply be overloaded or have dangerously faulty equipment, the local circuit breakers will cut the power to the stand automatically
• Exhibitors requiring a larger power supply may arrange this with the venue at an additional cost, up to a maximum rating as specified in the Electrical Rules. Because of the obvious fire and electrical danger, the rating of the supply must not be exceeded
• Contractors working at the venue must ensure that all power tools in use are suitable for use with the local supply
• Exhibitors and contractors are required to provide their own extension leads or adaptors and are responsible for them being properly wired and electrically tested. All electrical equipment and extension leads used must have been subject to combined inspection and test by a qualified electrician, including insulation and earth bonding tests, and must not be overloaded
• 'Daisy Chaining', the joining together of two or more multi-way extensions or plug-in adaptors, is strictly not allowed. This practice overloads circuits and can be a source of fire. Any ‘daisy chained’ units will be disconnected; removed and electrical power to the stand will be disconnected until the electrical contractor is satisfied that the installation is safe. The use of a multi-way plug-in adaptors and extension leads is restricted to one unit per fixed socket outlet
• Inspected equipment must be clearly labelled with inspection labels and a certificate of inspection must be available on the stand
• Any electrical equipment on the stand must be in good condition with live conductors enclosed and inaccessible, and cables properly protected against damage. Where an electrical installation is being wired or installed on site by the exhibitor, such work must be undertaken by a qualified electrician in accordance with the electrical safety rules and local wiring codes. As detailed in the rules, the electrical installation of each stand will have to be tested and certified before the stand is energised and will be disconnected if it is not properly installed and safe
• Any portable handheld electrical equipment used outdoors by contractors must be of double insulated standard and supplied from a circuit protected by a 30mA RCD
• Exhibitors and contractors are not permitted to carry out work on the venue’s electrical installation without written permission by the venue
• Electrical supplies to the stands must be isolated prior to dismantling
• The Organiser, the venue and their agents reserve the right to remove or disconnect any electrical equipment which either appears defective or has inadequate evidence of electrical inspection
• Exhibitors and contractors are advised follow the current Regulation of Low Voltage (Reglamento Electrotécnico de Baja Tensión) published in the Royal Decree 842/2002 (Real Decreto 842/2002). Only Spanish regulation will be accepted
• All clients' own fittings including displays and light boxes must be complete with all connectors fully enclosed and having an earth connection at every fitting
• Flexible leads for static appliances must not exceed 2m
• Stand switch-fuses must be always accessible
• Appliances must have been tested by competent persons before energising. The person bringing the equipment into the hall is responsible for the test being carried out
• Bare conductor catenary low voltage systems are not permitted
• Electrical installations that do not comply with the Regulations will not be energised
• The Organiser reserves the right to disconnect the electrical supply to any installation that in its opinion, the opinion of the electrical contractor or the venue, is dangerous or likely to cause annoyance to visitors or other exhibitors

• Isolation levels:
• Power supply main cable - The type of cable used in this segment shall be 0,6/1 kV isolation type
• Stand Installation - Conductors to be used in the stand installation must be 0.6/1kV isolation level
• Conductors of 450/750 V isolation level can be used with a rubber isolation (Type H07RN-F). For other isolations, please check tables 1 and 2 in electrical rules
• Colour code to identify the phase conductors is: black, brown or grey. Blue is identified for neutral conductor and the green / yellow for ground conductor
• Minimum section of the conductors depending on the protection installed

The ground conductor must be of the same section as the phase – neutral conductors until 16 mm2. From 16 mm2 on, it can be reduced by half

Metal structures, receptors and, in general, everything that has metal parts and that could become live if a fault occurred, shall be connected to the ground distribution

All lighting circuits and outlets of less than 32A shall be protected with 30 mA residual current circuit breaker (RCCB). All electrical equipment that is accessible to the public must be also protected with 30 mA RCCB.

All circuits must be protected against overcurrents with omnipolar cut off (phase-neutral) in its origin.

The venue has the following electrical specifications:

• Working voltages: 230 V single-phase, 400X three-phase
• Frequency: 50Hz
• Maximum single-phase supply: 6.6 kW (32A). Electrical connections with a power greater than 6kW must be carried out the form of three-phase installations
• Power factor for calculation: 0.85

Each service chest contains: communications, electricity, data, water supply and waste, TV and FM. The technical details of each chest are as follows:

• III 400 V (CEE plug)
• From 16 to 63amp supply
• 2 Connections of compressed air per service chest, 1000 l/ min. 6.5 bar
• 2 water supply connections per chest, half an inch, 4 bar, 32mm drainpipe
