BS6396

Standard for electrical installations in office and educational furniture connected to the supply by means of a 13A BS1363 plug – Standard UK square pin plug BS6396 applies to electrical installations in office and educational furniture connected to the supply by a 13A plug complying with BS1363 – the Standard UK square pin plug. Installations complying with BS6396 may also be specified in locations where UK electrical practice and sockets are also used such as the Eire, UAE, Singapore and Hong Kong. Furniture installations connected by other means such as underfloor track tap-offs, Industrial connectors or hard wiring should be installed in accordance with BS7671 Requirements for Electrical Installations. Recently updated to include furniture for use in educational establishments – Schools – Colleges – Libraries – Universities The latest review of BS6396 published in November 2008 widened the Scope of the Standard to include Educational furniture. Effectively bringing electrical installations in educational furniture connected by means of a 13A plug under the same rules as commercial office desks and workstations. This change was requested by the British Standard Committee with responsibility for Educational furniture to ensure that students in schools, colleges, universities and training establishments enjoy the same levels of safety as staff in commercial premises. Installations in these establishments connected by other means will need to comply with BS7671. Restricts the number of sockets connected from a single 13A plug to a maximum of 6 BS6396 restricts the maximum number of sockets fed from a single 13A plug supply to 6 when they are individually fused at 3.15A. These restrictions should not be exceeded as it may lead to overload or excessive earth leakage currents back to the supply. The sockets on BS6396 compliant installations are for use with equipment with a maximum current rating of 5A. The furniture mounted sockets must not be used for high current appliances such as kettles, vacuum cleaners, and heaters. If equipment exceeding this rating is to be used on the furniture this must be connected directly to its own 13A supply socket. The cable may be routed through the furniture. All sockets must be individually fused – 5A for a maximum of 4 sockets – 3.15A for a maximum of 6 sockets. OE Electrics power modules are fitted with ceramic anti-surge HRC fuses as standard. Replacements must be of the same type and rating and comply with the restrictions as previously indicated. Under no circumstances should glass fuses be used as replacements even though the rating may be the same. Furniture to be provided with facilities for cabling and sockets For compliance with BS6396 the furniture into which the electrical accessories and cabling are to be installed must comply with relevant structural strength and stability Standards. Facilities for mounting sockets in accessible locations, routes for cables and cable clamps should be provided. Modules available for both earthed and unearthed installations. For guidance please contact our Wakefield office. All OE Electrics modules are supplied with a facility for earthing the module to furniture. Some modules, such as POWERUNIT, POWERBOX, come complete with a 250mm long 1.5mm 2 earth bond cable terminated with M5 ring terminal as standard.

BS7671

BS7671- Installations complying with IEE Wiring Regulations including regulation 543.7 (formally Section 607) Electrical installations which are connected to the supply by any other means than a 13A plug (BS6396 installations) must comply with BS7671. In most instances within the modern office environment, this electrical installation is likely to be an underfloor track. Where the connection is supplying :

more than one work station (i.e. via a Power distribution unit ), or… multiple computers, for example on trading desks then the requirements of regulation 543.7 of BS7671 – Earthing for High Protective Conductor currents will need to be followed.

OE Electrics can provide bespoke solutions in these situations to ensure the operational requirements, as well as those of safety, standards and statutory regulations, are simply and cost-effectively achieved. Power distribution units can be supplied with:

sockets to feed directly to the desktop equipment or, with Wieland connectors to act as a central connection point on clusters of desks; feeding from this  point to power modules on individual desks. All of these units can be fitted with suitable circuit protection to meet regulations and ensure the safety of the installation.

OE Electrics have developed solutions to ease installation and allow the fit out of offices to proceed smoothly without conflict between trades working to deadlines. Where additional earth bonding is required, earthing kits can be developed, manufactured and packaged to meet the needs of the particular requirements. OE Electrics can provide:

  • Technical support – Designs to meet specification and tender requirements
  • Product ranges to meet most requirements simply and effectively
  • Fast turnaround with direct deliveries to site for large projects
