Electrical Safety & Electrical Equipment

There are important venue rules and regulations governing electrics on stands which must be adhered to at all times. Installation of power onto stands can only be undertaken by the RAI Amsterdam appointed electrical contractor Mansveld Expotech. 

  • It is the practice at the RAI Amsterdam to provide a 3-phase plus neutral supply of nominally 400 V, 50 Hz (3 x 230 V phase to neutral) to those stands that require a connection of more than 3 kW. The exhibitor is required to arrange that their total electrical load be balanced across the phases.
  • Fused switch boxes are not supplied unless ordered. Exhibitors are advised to bring their own if they want to be able to isolate their stand from the mains supply.
  • Stands that require no more than 3kW (power are provided with a single-phase supply (230 V 50 Hz), which is distributed from a nearby switch box installed by Mansveld Expotech.
  • Lighting and power units with a capacity larger than 3kW should be equally distributed over three phases. Electrical lines should be installed at a sufficient distance from steam, water or gas lines. Lines that are exposed to damage should be well protected. Motors should have a thermal safety switch. Motors with a power capacity larger than 3kW should also have a starter for which the starting current should not exceed 3 times the nominal current up to a maximum of 180 Amp.
  • All sockets, where supplied will be of the continental Schuko type.
  • If an exhibitor pre-wires a stand or has a prefabricated distribution system, then this will be subject to an inspection and test procedure before connection to the mains is permitted.
  • Technical crews should pay particular attention to power installations. Attention to detail is important, such as power cable diameter, power cable tidiness, proper earthing/fusing and addition of filtering to ensure harmonics (e.g. from lighting dimmers and switch-mode power supplies) are not returned to the power source. In addition, special attention to earthing is required where a transformer is used to deliver a 115 V feed.
  • Stand installation should incorporate cable with a minimum core diameter of 2.5 mm2 or equivalent. Power supply lines for lighting should have a minimum of 1.5mm core diameter, provided the needed power is no more than 2 kW (10 Amp fuse).
  • The use of thinner wires for power supply lines to wall sockets is strictly forbidden. Cables under floors should be a minimum of 2.5 mm2 and not interrupted. The installation should be distributed over sufficient groups and each group should have the necessary fuses. The maximum load per group is 3kw (13 Amp).
  • Welded joints should be made with wire connectors or terminal clamps. The hiding of welded joints behind walls, under floors or in ceilings is not permitted. All metal parts should be well earthed. Lines should be sufficiently secured. The electrical stand installation should be designed such that interference resulting from higher harmonics has no influence on the installation of the RAI Amsterdam distribution network.
  • 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 and 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 installation and earth bonding tests and must not be overloaded.
  • 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 sound condition with the 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 regulations on the electrical supply order form and local wiring codes.
  • When planning a Space Only stand, avoid the use of incandescent (theatre style) lighting, which generates heat. Use 'cold' lighting where possible. This produces less heat, which helps the exhibition hall air-cooling system.
  • RAI Amsterdam is equipped with 230Volt power supplies. If you require 115Volt, please contact RAI Exhibitor Services so they can assist you with a suitable converter. 

See Permissible Stand Building Materials for regulations governing lighting fixtures including the use of fluorescent tubes, neon appliances and ornamental fittings. 

IMPORTANT: Electrical installation can only be carried out by authorised electricians. The certification of the installation is a standard procedure carried out by Mansveld Expotech. If the stand installation does not meet the relevant regulations of Laagspanningsrichtlijnen, NEN 1010, NEN-EN50110-1, NEN 3140, the Fire Brigade and insurers, it cannot be connected to the power mains. Mansveld Expotech will charge re-certification of the installations as a result of not meeting the conditions and regulations, separately to the client. IBC, the RAI Amsterdam and their agents reserve the right to remove or disconnect any electrical equipment, which either appears defective or has inadequate evidence of electrical inspection.
